The Sennheiser Trio: HD580, HD600, HD650

This all started when I got a HD600 loaner from Jay. I told him I haven’t listened to the HD600 for a while, and asked him if I can borrow his HD600. Being the generous guy that Jay is, the HD600 arrived at my desk without much delay. The HD600 is similar to the HD650, but in a way it’s also different enough as it offers some things that you can’t seem to get with the HD650. I really enjoyed the HD600 that I decided to buy a new-old-stock HD580, which was discontinued a while ago. Now that I have all three members of the Trio in my hand, I decided to write a brief comparison between them.

The Trio apparently started life back in the Spring of 1993, with the release of the HD580 (there was also a wireless digital infra red HDi850 released in August 1993). Thanks to Tyll’s wonderful article at HeadRoom, I can get a sense of what it was like back then to have a HD580. To quote Tyll:

“The dynamic cans available in those days just wouldn’t hold a candle to the speed of the Mylar diaphragms and dedicated electronics of the e-stats. Then Sennheiser introduced the HD 580 and everybody that cared about headphones (there were like twelve of us back then) were stunned.”

“The HD 580 had punch and warmth, most headphones of the day were thinner sounding. There was speed and coherence up top, not the confusion and congestion that characterized the under-engineered “accessories” as they were thought of at the time. Sennheiser had really put some thought into these new cans and it was easy to hear.”

It seemed clear that the HD580 was quite a successful product, and on Sennheiser’s 50th Anniversary in 1995, the HD580 Jubilee Edition was released. The Jubilee is a limited edition version of the HD580 with a glossy carbon fiber look finish, a special box and special certificates. After the limited edition release is finished, Sennheiser continued the Jubilee into a regular production in 1996 as the HD600 (though without the certificate and the carbon fiber finishing). The HD600 supposedly have better acoustics and tighter driver matching than the HD580, although I can’t seem to differentiate the sound between the two (when you’ve changed the grills on the HD580, more on that later below).

In 2003, 10 years after the HD580, Sennheiser released the HD650. It seemed that they went around consulting almost everyone who cares about headphones, from high end audio people, engineers, journalists, and even internet forum members. From the HD650 Press Release:

“In their quest to develop even better dynamic headphones, Sennheiser consulted high-end specialists, sound engineers and trade journalists. They even consulted internet forums to complete the picture. This intensive research revealed an interesting fact: that listening habits have changed. Today, people prefer to “feel” the music rather than to analyze it. The result was the HD 650 – headphones that captivate the listener with the ultimate in lifelike reproduction, while still maintaining absolute precision.”

Indeed the research very accurately captured the kind of sound that people want to hear in a headphone. So accurate in fact, that even today many people still prefer the HD650 over the HD800’s sound. The HD650 become a headphone synonymous with its coloration, albeit a very pleasing coloration. While other headphones come and go, the HD580/600/650 continues to be respected among the enthusiasts circles, even by people who don’t enjoy them. At one point, the HD580, which is essentially a marked down HD600 is available for as low as $120. Never before has reference quality been so affordable. In the midst of the current race of $1,000 flagship headphones, I started to look back to the years when you can get the “best” headphone for merely $300.

HD650 disassembled.

 

Digging up further, I found an article by Wes Phillips that outlined even more of the changes on the HD650:

Sennheiser has actually used a tougher metal mesh for the earcups that shouldn’t dent as easily as the old stuff. (I welcomed this news — my 600s, which have traveled to many a recording session, are quite banged up.) The whole structure of the HD 650 seems far more solid and less resonant than that of its predecessors, possibly as a result of a stronger spring in the headband. Sennheiser states that it has beefed up the 650’s “baffling damper” — a membrane that controls the chamber resonances of and within the earcups themselves — for “tighter acoustic control.” If that means the headphones feel dead-quiet and free from any structural vibration, then: mission accomplished.

But the biggest changes in the HD 650 are the aluminum voice-coils, the new diaphragm material, and a Kevlar-shielded OFC cable that sports a dedicated 1/4″ phono plug (a phono-to-miniplug “cable reducer” is also provided). In addition to being made of a different material, the 650’s diaphragms are constructed differently — it’s a membrane of variable thickness that has been tuned by ear. Not only by ear — Sennheiser has comprehensive test and measurement facilities — but engineer Axel Grell found that when the ‘phones measured flat, they sounded harsh. So he very carefully tuned the response to have notches at 5kHz and 16kHz. These notches, speculates headphone maker-designer Tyll Hertsens, of HeadRoom, mimic the ridge notches of the concha — the largest and deepest concavity of the external ear, or pinna — which help you determine the azimuth and elevation of sounds.

So, from Wes Philips’ article, we learn of some additional differences between the HD650 to the predecessors. The HD650 has a more solid structure — this I can confirm. Not sure about the metal mesh, as I don’t want to damage my headphone to test it out, but that’s also possible. The beefier baffling damper is possible, seeing that the color for the HD650 assembly may indicate slightly different plastic material. All these changes would most probably contribute to a better acoustics, something that is definitely heard on the HD650. Then there is also the aluminum voice-coil, new diaphragm material, and a new cable. Interesting indeed. I won’t talk too much about the cables, but the aluminum voice coil and the new diaphragm with variable thickness may contribute very strongly to the superior HD650 soundstage (as we will discuss more thoroughly later).

 

With the right set up, the HD600 and the HD650 proved to be just as enjoyable to my ears as any of the thousand dollars offerings. Take the HD800 for instance, it has gobs of technicality superiorities over the HD650, and yet it didn’t win as many converts as the HD650 did. At a certain level, any additional technical superiority becomes irrelevant. And even if the HD650 may be inferior to new $1,000 flagships, it has enough technicalities to please just almost everyone outside the Electrostats-addicts. Perhaps the Sennheiser engineers were right when they opted for musicality rather than accuracy in developing the HD650.

    Just curious, when you say adequate amplification for the HD650s to have a good soundstage and be noticeably different from the HD580/600, which of the following from the amps you used were sufficient?
    AMB Beta22 (balanced and single ended), Eddie Current Zana Deux, Grace m902, Matrix M-Stage, Hifiman EF-5, Ibasso PB-1

    I was wondering at what price point does it become “sufficiently good” amplification and any more beyond a certain point requires a lot more money put into the amp to get a noticeable improvement?

    • Reply November 15, 2010

      Mike

      Excellent question, Danny.

      I actually had the same thing in mind when I was writing the article. At what price-point can you start to call an amplifier "sufficient" for the HD650?

      There is no easy way to draw the line of what's sufficient and what's not. I mean, an Ibasso PB-1 can drive them to a deafening volume level, and with a good amount of refinement as well. But is that sufficient? Someone with no prior amplifier experience (i.e HD600 direct on laptop) will call the PB-1 sufficient. But someone more experienced with amps will see the shortcomings of the PB-1.

      It's even harder for me personally, as most of my listening are done on fairly high end amplifiers, and so my ears have adjusted to that level. It's hard for me to listen to a budget amp with the HD600/650 as I can always see where the amplifier fails to produce the level of refinement that the phones are capable of.

      That's probably the best answer I can give for now.

        Thanks for the reply Mike. Just curious since the M-Stage got good reviews from you as well as people on Head-Fi: what (if any) deficiencies using the HD650s on the M-stage as compared to a higher end solid state?

        • Reply November 16, 2010

          Mike

          Oh, the difference is quite big, Danny. I still think that the M-Stage is a great amp, but with the HD650, I can feel that the amp is not that refined, even with OPA627 Class A. It has gobs of power, for sure, and it matches beautifully with the HE-5LE (better than the Beta22). But not with the HD650. Even the Concerto is already more refined than the M-Stage.

    no probs on that.. skimming thru briefly. nice breakout of the components, very informative.

    there is one thing that kinda runs thru my mind tho,

    HD600 is said to perform better with 650 grills and cables. it's already modding part, but since u have the 600 and 650, it probably nice to include some impression. it would also validate the point about acoustic improvement from housing materials. 🙂

    • Reply November 15, 2010

      Mike

      I've tried the swapping the HD600/HD650 cables and ended up going back to stock configuration. This is why:

      The HD650 cable adds low bass quantity, while the HD600 cable is more linear. Using the HD650 cable on the HD600 will add more bass quantity, using the HD600 cable on the HD650 will take off some bass quantity. Theoratically, it should work as some would probably want a tad more low bass on the HD600, and some would want a tad less low bass on the HD650. However, I do find that the bass frequency response is not as linear with the swapped cables. I think there is strong reasons to believe that Sennheiser tuned the drivers, acoustics, together with the cable, and the headphones sound the most coherent on the stock cables.

      About the grills, I'm honestly pretty amazed to see how the two seemingly identical grills is able to alter the sound slightly. I wouldn't call the change an improvement, more like a slight tune to the other direction.

      On the HD600, the HD650 grills boost the midrange presence a little, which I sort of like. But at the expense of a little less control. There is a slight upper-mid bass reverb that comes out from using this grill.

      On the HD650, the HD600 grills reduces the midrange presence a little, while adding a slightly better clarity on the midrange and upper bass. Frequency response sounded a tad recessed and less coherent than with the original grills though.

      Keep in mind that I use the word "slightly", "little", "a tad", and so on..

        Wow, we agree on a lot of things Ive noticed. I thought The hd600 stock cables were better than the hd650 cables on the hd580 and the 600 too. I thought the 650 cable took away from some of the cans coherence and the mids sounded cheaper with the 650 cable. The highs were actually also affected as if the lower highs were more edgy from memory and it made the sound less airy because of that.

        • Reply November 16, 2010

          Mike

          Amazing!

          I honestly didn't notice the changes to the lower highs and airiness, but it may just be my ears.

            donunus

            basically the sound became a little more V-shaped except the bass was a little more pronounced than the treble part making them lose some air on the very top. The mids become a little more recessed because of this little extra brightness in the treble(7-10khz) below the top end air zone. I didn't give my hd650 cables time to burn in though since I instantly hated them compared to the stock ones, so that could be the reason for the extra brightness I heard vs your hd650 cables 🙂

      For now, the Burson at ~$600 would be my strongest recommendation for HD600/HD650. If you don't mind DIY, the TK2050 Tripath amp ($100) would also be wonderful, though not quite to the level of the Burson. I'm writing a review of it soon.

    I’ve been a mastering engineer for some years(i still do some mastering).
    When i had to choose my reference can i asked both to Bob Katz and Steve Hoffman(the most audiophiles audio mastering engineers you can find) which was the headphone they were using for monitoring/mastering purposes.
    They both answered : Sennheiser Hd 600.
    Since 2007 i’ve only used this can with a lot of satisfaction.
    My main rig is totally balanced and it uses constant current drive
    techonolgy.I run my hd 600 balanced with a custom cable made of CryoParts SCSCag Hook Up Wire.I can clearly say that the tonal response is very neutral.I always been intrigued by the hd 650 but its own more colored frequency response and somewhat “slow” response to transients
    puts mu curiosity almost to an end.
    I think that the hd 600 can also sound different by the amplifier you use.
    I had one good sound with my lake people G100 amplifier but now i have
    a really excellent sound with my hpba2-s by qes labs.
    So thumbs up for the hd 600!

      Thanks for the comments Frank. Certainly, using the HD650 would make your mix bass-light.

      The CryoParts SCSCag wire is very popular in our local circle, but it's very stiff to be used as a headphone cable (although one guy uses a SCSCag wire for his portable HD25-1!).

      I'm interested in the Lake People and HPBA2 amp. Perhaps one day I can listen to them.

    Ibasso now sells Sennheiser balanced cables for $39 off their website. The cables are made for the Toucan, as they are terminated in the Hirose connector. Because the Toucan was made to be run balanced, maybe you could do an article about the Toucan and the HD series? It would appeal to many people, as it is semi-budget.

    During my reading through head-fi I have noticed that back in 2003-2005 when the HD650 were fairly new people considered them to be very similar to the HD600. I have even seen few posts saying it's not worth to go for the HD650 since they sound almost identical just like HD580 and HD600. I find it funny that it took about 2 or 3 years for such a big community to realise how different these headphones can be. I actually can imagine someone 'testing' HD650 and HD650 on mediacore AMP and describing it as very similar. I can also imagine how the rest of head-fiers started to repeat this opinion having not tested both. Disadvantages of having big communities I guess. Another funny thing is how the HD600 was loved during ~2000 period and now people say it's 'bad', veiled, dark and dull. Possibly the part of that Beyer DT880/600 'hype' that we have since nearly a year.

    Also one thing – you have recently praised the HD650 quite a lot and you even said you think they are better performers (well not exactly but that could be a general conclusion) than K701 and DT880. Be prepared for a war with Senn-haters!

      Hi Professor,
      Thanks for sharing your thoughts. You know, I started this hobby with the ER-4S, and back then I couldn’t understand what the HD650 were all about. Of course, we were all drooling for the Grado RS1 back then, which sells for almost double the price of the HD650 (on the street). But after some time, nobody in our forum would even consider buying the RS1, while the HD580/600/650 continues to be highly sought. Interesting changes indeed.

    Interesting article, Mike!

    Pretty much agreed on the points covered. Although I must mention that the HD600 is by no means bass-shy as the article seems to suggest. Fresh out of the box the bass can be a tad overwhelming.

    I agree that the pace the 600's carry would pretty much make it happy with most tunes, just avoid loudness war material with it. It behaves exactly as advertised (in the UK, they are classed as music monitors). So if you feed it well-mastered/well-recorded tunes, it will tell you they're fine and vice versa.

    Unlike typical monitors, do note that the music can be very engaging too (down to the pace again?). Kinda reminds me of the sound you'll get in a well-set up producer's studio or theatre.

    Certainly not regretting the purchase. 😀

    @Kelvin – I'm very happy you're enjoying you new headphones! I like my HD580 too.:D

    About the bass – I find it to be exactly as it should. Not too much and not lacking. At least in general because on some recordings the bass can be overwhelming whereas on the others it does not appear at all (just my impression though). Still I think it is good these headphones have some wieght to the music. The bad thing about the HD580 is that it made me wonder how HD650 might sound like and since I really have no option to demo them. But then again – HD650 will have too much wieght in certain cases. I have not heard them but being an owner of the HD580 and listening to very wide range of music I know that specific recordings will not sound good with headphones that have more wieght and bass. I will then buy complimentary cans that will have less weight. And this is the story of how I am going to lose another $$$ during a year, lol. I am not sad though (not now when I think it's worth it).

      Yup, I certainly do. Although I must mention I had to readjust myself a little to suit the headphones, which actually meant it still isn’t the most ideal.

      That brings me on to the bass. I don’t think this simply adds weight to the music per se. Early on (even sometimes now), I’m under the impression I’ve strapped 2 subwoofers to my head and let them POUND the bass notes into my brain. Or it could be that I’m just too used to a more mid-centric presentation.

      For myself, a DAC + Amp combo (or a one-box) will certainly follow when I have budget again. High chance being the CEntrance DACport for now.

      Hmm…complimentary cans. I seriously don’t know if that’s a good idea. If I were you, though, I would probably opt for the 598. It has a very open presentation compared to the 600 and definitely a lot more relaxed with the lower registers. That is not to say it doesn’t punch low, though. Music is still rather weighty on the 598, just not on the same scale as the 600.

        Hd600 has a flatter and more neutral freq response

        compared to the hd 650.i was talking about defoam,silver recable just to remove the bump in the low-mid frequencies

        and to open the sound in the high frequency range.

        Then if you ask audio engineers 7 out of 10 prefer the hd 600 🙂

        By the way if sennheiser is going to discontinue both of them

        i'll buy another hd600 just be sure to have a replacement 😉

    After a clarification email from Sennheiser, I have edited the introduction paragraph with the launch dates. This is direct from Axel Grell at Sennheiser:

    Hi Mike,

    I read your write-up "The Sennheiser Trio" as well as the readers' comments on the launch of the HD 580.

    Then I decided to get in touch with Axel Grell and he told me that the HD 580 was launched in Spring 1993 while the wireless digital infra red version (HDi850) was launched in August 1993.

    The limited edition HD 580 Jubilee (for Sennheiser's 50th anniversary) was launched in 1995. HD 600 was launched in 1996 and HD 650 in 2003.

    As for your DM on the HD 600/650 discontinuation, it's still just a rumour 🙂

    call me crazy or what but i'm not an audiophile.I tend to evaluate thing from a pro point of view.
    Tonight i've just tried a mod on my spare pair of hd 600(bought 2 years ago and well burnt-in).
    I've just removed the foam on the outside of bothy drivers(the small ones).
    There's clearly a change!!!
    The upper registry opens a bit.The sound of bass seems to me less congested and has a more natural sound.A little more speed on transients.
    Before removing the foams on the outside of the drivers i've listened 2 times to a song i'm extreme familiar with.And i've done the comparison listening to the same song
    after the mod:there's clearly a change.I'ts not snake oil.Try for yourself.
    I'm not an audiophile.I've been using the hd 600 since 2008 and i deeply know its own sound signature.i really like the improvement.

      Youre talking about the small foam behind the drivers right?
      As far as the foam in front, I don't like the ringyness that happens when taking out the foam. It also makes the bass thinner. Maybe the ringyness without the front foam has something to do with reverberations in there not being tamed enough.

      Thanks, Frank. That's something I've never tried before. I don't think you're being delusional, as little things Sennheiser planted in the assembly seems to work together to fine tune the overall sound.

      I've tried removing the foam in front, and like donunus, I didn't like the result as well (although it did make the sound a little brighter, which some people may like).

      Now, which little foam outside of the drivers did you exactly remove again??

        the foam here :

        i think you can clearly see it in the picture and how to remove it 😉

        the problem is that once you've done it it will be pretty difficult to put the little foam
        back on the original position.But the sound improves for sure! so it's worth doing it 😉

          Ah, I’ve read that document a long time ago but I’ve forgotten about it!

          So, it’s sort of a gambling… take it off and I may not like the end result. Because my experience is when you mod something, you gain one area and you lose the other. Surely the engineers at Sennheiser have their considerations for putting that foam there.

    Thanks a lot for the reviews, Mike. After reading both your comparisons, I think I was right in thinking about a HD600.

    I was postponing the purchase primarily because searching through head-fi confused me more than clarify about the strengths and weaknesses of the contenders – AKG K701/2, DT880/600 and HD600 (I was not considering HD650 due to the colored signature).

    I already have a HRT MS2 for DAC and Maverick TubeMagic D1 as a Headphone Amp. I’m thinking of later upgrading to Burson HA160 as a headphone amp and may be HRT MS2+ for DAC. Do you think the setup I have and plan to have are good enough for HD600? Any other options I should think of (cheaper the better, of course ;))?

      Hi Eswar, I think the HRT MS2+ and Burson would be more than adequate for the HD600. You can even stick with the MS2 DAC, and I'd still think that'll be a great set up.

    Allright, I have to write something…

    First: wonderful site. I enjoy reading your articles tremendously.

    Second: this article is immensely true… I don´t know the moment anymore when I bought my 600 but I still knew that I replaced my 580 with them. And until the 580 I used the more expensive, closed Sony´s (CD-1000). My first Sennheiser was a revelation, I literally fell for them on the first listen. I believe my 600 are now seven years old and until three years ago I listened to them via my headphone output of my multichannel amplifier. So far, they improved with every step I made regarding amplification. Right now, they are powered by the amp inside the ASUS Xonar Essence ST. Mike, do you think that this is sufficient? I still have a Corda Arietta but it colours the sound a bit.

    I also use the 600 with the 650 cable and I love it. It takes away the slight sibilance that hinders differentiation present with the stock cable. It would be horrible if Sennheiser would discontinue them…

      Hi Marlene, thanks for the kind words, even as we're going through some major changes in the website — fixing glitches and changing design and all…

      Thanks for sharing your impressions. When the HD600 was released, I didn't even know what a good headphone is, so I didn't know what it was like back then.

      Now, I guess you're asking about the amplification. I've never heard how the Xonar sounds (gosh I really need to find one), but as far as I know, they are based on the fairly powerful TPA6120 amplifier chip. I think that should be enough to drive the HD600. Plus, if you feel that the music is good with that set up, then the music is good.

      When I started, I've always wondered that if a more expensive amplifier would improve my music experience. But after going through so many amplifiers, that is not necessarily true. A good amplifier+headphone pairing is a good pairing regardless of the price. And sometimes more expensive unit may not better that, though technically things may improve.

      Having said that, what amplifier do you have in mind to upgrade to? How much budget are you thinking of spending?

        Hey Mike, thanks for your answer!

        I know the feeling, not knowing how a good headphone actually sounds. In hindsight I´ve experienced this for years… you wouldn´t believe the crap with which I started.
        Anyway, I really feel that the music sounds the best (compared to what I was having before) with my current setup. When I´m listening to music that I haven´t heard for years I´m constantly baffled at how much the sound differs from what I was used to listen to many years ago. So I don´t exactly plan to upgrade my amplifier, this has not yet crossed my mind. On the other hand, the 600 grew with every source/amplifiying improvement I´ve made so far. I just wanted to ask a general question if an improvement is possible because I think it COULD be possible.

        But if you say that sometimes things can be overkill (supposing that I understood you correctly) I´m very confident that I have something good for the price I´ve paid. Of course, one always wants to improve the setup, that´s what makes this hobby so darn interesting.

        Furthermore, some of the things you talk about in your articles are fairly hard to get here in Germany, I would have problems obtaining them. Take headphone cables for example, it´s almost impossible to get them here. Many of those can only be ordered via credit card and I won´t get a credit card only for my headphone. I don´t love it that much I suppose 😀

        Anyway, thanks for your reply!

          You're based in Germany? I don't live there, but I think there are a lot of things that you can get, being based in Germany.

          Reading from your comments, I think the Xonar probably does a fairly good job of driving the HD600s, which is easier to drive than the HD650 anyway. There are several upgrade paths that you can take, but it's hard to give a precise recommendation as high end amplifiers tend to have their own characters. It's like Mercedes or BMW, both very good, but people will still have their own preference.

          For instance, the two amps that you can probably get easily is the Lehmann Linear and the CEC HD53N. The Lehmann is more precise, accurate, and uncolored, where the CEC has a warmer tone and a sweeter midrange. Some people would like the Lehmann, and some other would like the CEC. So, it would be good if you can tell us a little bit about your music.

          I can also recommend you to get an upgrade in your source by getting a newer DAC, but since you already have the Xonar, I think an amplifier upgrade is better. 🙂

    even if i've said that elsewhere this is what i've learned doing many tests:

    1)Both hd 600 and hd650 headphones need proper burn in

    2)Hd650 needs a powerful amplifier to drive them.
    Hd600 it's easier to drive.Hd600 is far more neutral compared to hd650.

    3)Both headphones improve a lot their perfomance if you use a balanced configuration with a real balanced amplifier.Since i've bought this one i've never looked back :
    http://www.gearslutz.com/board/mastering-forum/47

    4)Both headphones improve frequency response if you use a silver cable.
    High frequencies are more upfront,bass becomes tighter and you have
    more speed on transients.

    5)Both headphones open their frequency response by removing the little foam on the outside of the drivers.

    just my two cents

    I posted the comment before Shahrose. I now have Nuforce HDP and HD650. It's a decent combo, but I find it a little lacking at lower volumes which I prefer at my listening. The problem seems to be a lack of soundstage or resolution or both. As a beginner I'm not sure about all the hifi words.:D Somehow I don't hear a lot of sounds and instruments as well as with higher volumes.

    Would an good amplifier such as the auditor etc. Solve this problem and increase the soundstage and resolution at lower and at very low volumes.

    Thanks for your earlier reply!

      Will, I'm writing this as I'm listening to a HD650 out of an Ipod/Pico Slim combo. As you know, the Pico Slim doesn't have too much power. At lower volume, the apparent soundstage size decreases, but I think that's expected from any headphone. But at this set up playing at quite a low volume, I don't feel that the resolution has been lowered. Of course it's hard to hear all the details as if I'm listening at a louder volume, but I think the driver still resolves quite a good level of detail.

      I also checked this with the Burson HA-160D and found pretty much the same result.

    • Reply January 15, 2011

      Mike

      I was curious, and so I turned on the 4-ch Beta22 with the HD800 in balanced, and I tried to check the low volume performance of that set-up. This is probably as good as a solid-state set up can get.

      What I find was mostly similar than with the HD650/Burson or HD650/Pico Slim.

      At low volume, the soundstage is smaller, and though I can't hear ambiance cues as well, I don't feel that the resolution of the driver has lessened in playing the instruments that I can still hear quite clearly. I think what happened is that the ambiance cues are washed out in this volume level simply because they have reached a dB level far too low for my ears to capture. As soundstage information is also happening at the high treble frequencies, the soundstage also got smaller because those information has now dropped to a very low dB level and my ears can't hear them anymore.

      Hope this answer will suffice. 😀

    That's actually good news since the increase of low volume performance was pretty much the only reason I was interested about a more expensive amplifier. So if I want to improve the performance the only option is cranking up the volume and having shorter listening sessions then?

    I'm not sure if you're familiar with Audio-GD and their line of amplifiers, but if you are I would really value your opinion. I have the Sparrow Amplifier, and I'm trying to decide between the HD598, HD600, and HD650. Based on your reviews, I think I might like the HD650 the most, but I'm not sure that my amplifier is up to snuff for the job, particularly in terms of the soundstage. Because of this, the 598 seems like a safe choice, but when I had the HD555's, I always found them to be lighter on bass than I would have liked.

      Hi Charlie, the 598 is going to be even lighter on the bass. The HD650 and HD600 both have better bass than the 5** series, and I'd recommend the HD600 as it's generally easier to amplify.

    As of today I own the proud owner of a secondhand but mint HD580! I bough them for $110. The first thing I do after obtaining a new pair of headphones is reading your site to see if you have anything to say about them. 🙂 This way I learned about the grill-mod (I’ll buy some spare HD600 grills) and am now looking for a good amplifier to go with them. The only amp currently in my possession is the Arrow 12HE but I’m looking for a nice desktop solution. Is there a hidden gem, a mighty back-for-your-buck giantslayer, I definitely should look into? 😉 Let me know!

    Also, would you say a dedicated $250 DAC (audio-gd, firestone, matrix, nuforce etc) would offer a worthwhile investment over my current Tascam US-122L DAC or Creative X-Fi soundcard?

        I’m always a bang-for-your-buck kinda guy. I buy most of my equipment secondhand or look into products that offer great performance at a reasonable price, hence my appreciation for the Superlux HD668b. Do an amp & dac HAVE to cost $500 to sound good? I’d try vintage receivers before shelling out for a Burson for example.

        Anyway, my ideal solution would be a DAC that sounds noticeably better than my soundcard hooked to an amp that can power my headphones (ATH, Grado, Senn, Superlux, Sony) but can also power a pair of bookshelf speakers. This setup would ideally cost less than $500. 🙂

              In general, pro-gears are more linear in frequency response, while audiophile gears tend to be more colored and placing more importance on midrange qualities.

          Yes, open headphones have their advantages, but for your music, it’s
          going to be very hard to get the kind of fast-paced, tight bass, from
          open headphones. The HD598 is voiced more for jazz and vocals, I really

      For symphonies, the W1000X is good, but it doesn’t quite have the low end slam of he Hd650. German headphones, you know? I am quite sure the Beethoven 9th was used extensively in tuning the headphone. Lol.

      Anyway, I haven’t listened to the W1000X for a long time, so I am probably not the best guy to ask. But what I remember is that the closed housing still have some reverbs, which is very annoying for Symphonies, and the bottom end impact can’t match the HD650’s.

      Between the HD600 and the HD650, I’ll take the HD650 (again) due to the better soundstage and low end impact.

      They do make a difference. Slight though, and the biggest change you get is still with a proper amplifier and source. If your system is 90% ideal and you want a tiny little bit of tuning, then get different cables.

    Mike recently asked me on Twitter about how the HD 600 was for heavy rock/metal music, and my reply was a bit long, so I’ll share some of my thoughts about that here along with some of my general findings with the HD 600.

    Mike’s HD 600 / 650 / 598 review is a great comparison of those models, and I’ll mainly focus on the HD 600 here.

    Firstly, the HD600 has changed the way I hear music, wonderfully so.

    I find the HD 600 quite neutral and with them, I hear the details on a recording with plenty of pace and clarity and nothing seems to be overemphasized; the HD600 clearly portrays the whole picture of the recordings I hear. It’s a great all-round headphone that can work really well with most types of music, including rock music.

    — Rocking out with the HD 600 —

    With the HD600, if I listen to music such as heavy rock and metal, I can certainly rock out, and the ‘rock out factor’ is largely determined by the quality and sonic balance of the recording I’m listening to. Using the HD 600 and flat EQ, I’m probably more likely to rock out and move to recordings that have more low-end weight which moves the HD 600 diaphragms more.

    ‘Freedom’ by Rage Against The Machine is an example of a heavy rock recording that has quite a bit of low-end weight to it. I just listened to it with the HD 600 in the process of writing this and found myself rocking and moving my body, quite enjoyably. ☺

    The HD 600 provides a subtler experience of rock music than with headphones such as the Sennheiser HD 25-1 or Grado PS-1, which are more ‘forward,’ sounding, and the HD 600 and could be described as a bit thin or light for some tastes, but if the recording is of good quality then the HD 600 will reflect that and reveal the vibe of the music with clarity.

    With the HD 600, the sonic detail and quality of well-recorded music is a treat. Music with relatively complex parts e.g. Lateralus’ by Tool is great to hear. With the HD 600, the drums on ‘Lateralus’ have plenty of PRaT, though at the end of the song, I’ve sometimes wanted to feel more sub bass, but I enjoy hearing the bass relative to the other parts of the recording. It seems that when I use the HD 600, I constantly listen to the overall picture of the music as my default perspective.

    With fast-paced music, such as songs by the heavy metal band Slayer, the HD 600 isn’t as ‘forward’ and ‘aggressive’ as headphones like the Grado PS-I can make music sound, but the HD600 is a relatively softer listen and easier on the ears which still provides plenty of pace and clarity.

    If you intend to listen to faster-paced rock music with the HD 600, I’d also recommend using a DAC/Amp to enhance clarity and impact. When I used the HD 600 via my laptop’s headphone out, the details in fast rock music were rather difficult to hear, but the DAC/Amp I used was quite inexpensive and made the computer noise disappear and the music sound clearer with more visceral impact, which I found satisfying.

    — Some overall impressions of the HD 600 —

    The HD 600 is a great all-round, neutral sounding headphone that facilitates hearing the whole picture of a recording. Listening with the HD 600 is what I imagine it would be like to listen to music via high-quality neutral-sounding monitor speakers with a thin sheet of fabric between the speakers and my ears (to illustrate how the HD 600 seems to soften the treble slightly).

    I really enjoy the HD 600, and rank it among the ‘best’ headphones on the planet at this (‘best’ being totally subjective, of course). I’d like to say that someone I know who owns a Sennheiser Orpheus said that ‘you can’t go wrong with the HD 600,’ and I think that says a lot.

    But at the end of the day, it’s the music that matters. Since I got the HD 600, I stopped listening to headphones as much and started listening to music more. The HD 600 really get out of the way and put the music on display. I like that. ☺

      Hey man, all those comments asking more sub bass make me think you should go and try out the HD650. Mine is out on a loaner at the moment, when it’s back I’ll give it a try with RATM and Slayer.

      Also did you end up getting a DAC/Amp box? The Yulong U100 sounds exactly like what you need. It should make the HD600 more forward and adds better bass articulation and punch.

        Hey there,
        I have the HD 650, which is great, but a little boomy in the bass at times, esp. with faster-paced music.
        I wanted to go for the Yulong, but I’m a Mac user and remember what you said about the Yulong’s Mac compatibility issues, so I opted for the the Nuforce Icon HDP. It makes the HD 650 a little brighter and tightens up the bass a bit, which makes it like a new headphone to me. 🙂
        The HDP adds punch to the HD 600, but the treble is bright to the point where my ears are ringing slightly even after short listening sessions.
        I was considering the Lavry DA10 as something more neutral, but you said it was cold and bright and recommended the HRT MSII+, so I checked it out and it apparently pairs very well with the HDP, which is best as a head amp.
        In the meantime, I’ve applied some EQ to the HDP making it work well in iTunes, but then audio from the rest of the OS is bright. It’d be nice to just have a simple high-quality neutral DAC/Amp solution…
        In the meantime, I have a cool product by Lexicon. It’s the Alpha USB interface (24/96) – great value product. 🙂

          Ah, I see. Yes the HD650’s bass is a difficult to control well.

          So you’ve gotten the HRT 2+ ?

            Not yet, but I may give the HRT 2+ a listen today at a nearby store to see if using it as a DAC for the HDP seems worth the upgrade. I not sure I want to spend hundreds of dollars if the upgrade is marginal though…

            I guess I want the best quality simple system that I can transport with my laptop. The HDP is definitely ‘good enough,’ and I love my HD 600 / 650 / 25 etc. I can do without the excessive brightness of the HDP.

            I shall meditate upon it. 😉

              Windsor,
              With your music, I think the HRT’s bass is not articulate enough for
              Hard rock and the metal stuff that you listen to. It is warm and analog
              sounding, but not articulate enough in the bass. I guess that makes the
              Lavry a good candidate, but I do think the treble issue may not go away
              with the Lavry.

                Hey Mike – thanks for the response.
                These days I don’t listen to much hard rock/metal, but I revisited some recordings to share my impressions with you and headfonia community in response to your question. It definitely provided quite a bit of insight into how much of a difference the recording makes to the listening experience.I want my system play music well without getting in the way, whatever I listen to (be that jazz, metal, classical, R&B etc) hence my appeal for neutrality and the Lavry. It could also be used for pro studio applications if I take that route.I may have an opportunity to try the Lavry v. soon. When I hear music with it, I’ll most probably know if it’s for me.

      Hey Windsor, my HD600 arrived today, and unfortunately my Yulong U100 is still being delivered, however I was able to use it out of my reciever and listen to some of the cable music which obviously is not the best of quality but it gave me an example of the HD600, holy cow after hearing a lot of cans the one word that comes to mind is Clarity, everything is clear and im sure that has to do with its close ot flat response the pace is pretty quick as well, I tested it on some alternative and metal, and like you said the bass may be a little shy for those recordings I’m hoping the U100 may fill the gap, if not I will get the HD25 / Pro700Mk2 for my stuff that requires a bit more in the bass department but either way the HD600 are here to stay, I’ll comment more when the Yulong comes in, but so far they have left a very positive reaction with their extreme clarity and balanced sound sig. I really see now why its had such a following even after all these years its been on the market. Thanks again to you and Mike for recomending I give it a try, regardless if it will work with my Trance and heavier metal music they will be staying for other genres.

      Windsor:
      I am responding to your very thorough post in the HD 580/600/650 comments six months ago. So I’m gambling a bit that you’ll even see this. My Q: I have the AKG K701 and too often find them cold and steely. I had the HD 650 and found it murky and muffled. I have been thinking that the HD 600 might be the answer: right in the middle. But now I am also thinking maybe my Fiio E9 amp at that time wasn’t up to driving the 650 properly, and maybe the Bellari HA 540 tube/ss hybrid I now use would open up the 650 somewhat, “put some air in it.” I mainly listen to classical and jazz, plus some female vocal. I come from a purist high-end audio background and want to stay away from eq in my main system (where I run the CD straight into the HP amp). Can you help? Any other suggestions? I’m not sure which way to go at present. Thanks.

        Not sure if you’ll see this, but I’d definitely recommend the HD 600 based on your preferences. I haven’t heard the K701, and have found the HD 650 to sound muddy at times, whereas the HD 600 got out of the way of the recordings more. Thumbs up for the HD 600!

    Hi Mike,

    Need your advice regarding HD600 and HD650 as my “be all end all” home headphones (I hope :p). My budget’s not really high, so I’ll prolly be purchasing e yulong u100 to match these phones, seeing how you recommended them as a good pairing dac/amp at a budget (I don’t have either dac or amp currently). But I’m wondering if I should go with e HD600 for genre bandwidth, or theHD650 for future scalability and jazz?

    I listen to a wide genre except heavy metal and hip/hop.

    Quite torn between the two cos of the price diff, and yet I don’t mind more bass for my alt rock n electronica songs. Having said that, the savings made on the HD600 could go to the u100, lightening my financial load… Any thoughts?

      I’d just go for the HD600 if you are in doubt.

      The HD650’s scalability is something you’d probably be concerned years from now when you have a good high end amp. Plus the HD600 works better for rock and electronica.

    Hey Mike.!
    The next purchase I had in mind was a Senn HD650!
    Seems these guys are really scalable and I would do alright with my current Nuforce Icon HDP and most of the amps I’m looking to buy in the immediate future…

    But after reading this, maybe I would prefer the HD600 (I listen to Rock, Punk, Emo, some electronica, some Blues, etc.) or even… gasp… the new HIFIMAN HE-300! Seeing that I have an AD700, Shure SRH 440, 940, etc. with which headphone should I go as my “LAST” top end can without destroying my wallet?!?HD650, 600, HE-300 or another one (i.e. I’d like something like the 940s but with a bit bottom-end and great for the genres posted above…)Thanks a bunch!

      Hi Angel,
      How do you find the AD700 and the Shures to be?

      The HD600 seems like a better choice for the stuff that you listen to. And as for the HD650’s scalability, it doesn’t start to be obvious until you get to the $1K-$2K amps.

      • Reply August 11, 2011

        Angel Melendez

         I love my Shure’s!! 😉

        The 940s I find a bit bright but great mids, I just love how vocals (especially women) sound with these. Bass extension is Ok, but it really lacks in that area. Hopefully my JDSLabs Cmoy will arrive soon and I’ll see if it at least gets a bit better there.

        To give some background, right now the 940s are my everyday portable/office headphones. Pretty Good isolation, velour pads are comfortable and my music sound quite good out of my mp3 player. As you and a lot of people have mentioned, the source is really important. I have some mp3s that plain sounds BAD! Good recordings, resolution make these headphones shine.
        Have only used them twice for monitoring, liked what I heard (did a comparison mixing a track with these and with the 440s… I mostly messed up the bass! :-p)

        The 440s are the cans that I have spent most time with. I’ve been using them with the 840 pads for more than a year and the pads actually makes a good difference adding a bit more body to an already good all-rounder (in my opinion, this is the most musical, good high end, great mids, and decent bass. Soundstage a bit constricted but oh well… Isolation is perfect.)

        The AD700s, I’m still getting used to the sound as I’ve been using closed-back headphones for the past 3 years. Still, soundstage seems HUGE and right now I’m using them on my PC directly to play games and the occasional music/movie playing. In the music front, they sound quite Ok to me, but they also lack bottom-end, and maybe the openness of them make them sound… I don’t know, less tight might be the word I’m looking for. Still prefer the Shures over this one BUT for the use I give them, they perform admirably! I have to say though, these are the MOST COMFORTABLE HEADPHONES I have ever used!!!

        Getting back to the original question though, that’s what I keep hearing, the HD600 might be more suited for what I listen to.

        Right now, the 440s are the ones connected to the Icon HDP. I know that those cans are fairly easy to drive so maybe it’s a bit of an overkill to be using the 440s with that DAC/Amp combo. I tried using the 940s with the HDP, but to me a good pairing does not make (seemed to make the 940s even brighter, didn’t notice any bass extension, etc.) So basically I’m looking to upgrade my “home” headphones (440s) with something that will sound good with the kind of bright HDP amp section and that will scale a bit if/when I decide to go with another amp.

        I know that purchasing for the present and the future is a bit tricky (that’s like buying a CPU or video card… almost ;-p ), but you know, at least something that will kick the 440s butt and extends my home setup a bit more.

        Thanks!

          I think you will be happy with the HD600. It will give you the sort of resolution of the Shure 940 but being a little less dry. It’ll also give you better bass than the AD700, though the soundstage size is not going to be as big as the AD700.

            Sorry for asking so many questions, I just value your opinion more 🙂 What about the DT880? How does its timbre compare to the HD600 and its synergy with  the Asgard? Also, how do the AD900, HD600 and DT880 compare in overall technicalities? I listen to a lot of folk, country and female vocals but also the occasional classic rock. I realize the AD900’s imaging is a little vague due to its big soundstage. I really love my EX1000. Perhaps, something similar but with the benefits of a full size cans? Thanks!!

              DT880 and HD600 timbre: DT880 is good but HD600 is better. Again HD600/650 has perhaps one of the best timbre ever, even better than a lot more expensive cans.
              Technicalities:
              DT880: most resolving, most detailed, most articulate, most accurate imaging AD900: least detailed, very spacious but not so three dimensional HD600: detail perhaps same to DT880 but not as upfront, articulation is okay, soundstage smallest of the three.
              But if you’re just evaluating headphones in terms of technicalities, or soundstage performance, you’re not getting the big picture. It’s like buying a car based on “which has the best shock absorbers”.
              Please read my Sennheiser article, read the Old school trio article, and read the AD-line up article. Then try to get the big picture of the character of each headphones, and then decide from there. NOT from soundstage comparisons, timbre comparison et cetera. http://www.headfonia.com/audio-technica-ad-series-ad300-ad700-ad900-ad1000prm-ad2000/ http://www.headfonia.com/the-sennheiser-trio-hd580-hd600-hd650/ http://www.headfonia.com/old-school-trio-akg-k701-beyer-dt880-sennheiser-hd650/

            Thanks for the quick reply. I like to categorize the headphones according to their individual technicalities. This way, I know what to expect when buying them. I chose the AD900 based on many reviews praising its soundstage and balanced sound. But what those reviews / recommendations don’t tell me is its vague imaging and inaccurate timbre, both which happen to annoy me a lot and kills the fun from listening to them.

    Copy and pasted from another comment that I wrote: 

    “Okay for the last time: 
    HD558 mod vs HD598. Still very different, and yes the HD598 is still the better sounding headphone. Sennheiser engineers know what they are doing and a simple foam removal mod isn’t going to do it. As for the HD600 vs HD598, The HD598 excels in certain areas like vocal and soundstage depth, soundstage image. But overall the HD600 is still the higher end headphone. The HD598 is the newer release and I suppose Sennheiser have learned a lot more things from the HD600 days and that’s why it’s able to accomplish some things better like soundstage and vocal but overall it’s still proper that the HD600 earns the higher model number. I would brand the HD598 as a very fine Hifi headphone. It sounds good and among the best sounding headphones I’ve listened to. The HD600 on the other hand is a solid reference-class headphone and in that sense it’s a higher up headphone than the HD598 is. The HD600 still sounds very musical, but on top of the musicality you get added points such as a far more accurate timbre and a more proper bass impact both of which the HD598 doesn’t have. 
    Now interestingly if you happen to have a $2,000 headphone amp, the HD598 scales up better than the HD600.. and again I suspect that’s some of the things Sennheiser engineers have learned over the time which they didn’t quite have when they designed the HD600. But for most people, I doubt they’ll be pairing the HD598 with a $2K amp. “

      The HD650 however scales up very well up to the $5000 desktop amplifiers, so I wouldn’t really focus on trying to get all the performance out of it since it’s going to be very costly.

    First off…great site. I currently own the Grado SR-225i…and may eventually move up the Grado line. Knowing that Grado’s shine in the high/treble and mid-range category would snagging the HD 650 give me me more rounded out coverage as far as sound goes? I read your reviews…but did not see this question posted . My DAC/Amp coverage is good now…and may upgrade to the Nuforce Icon HDP soon…or maybe a keep my current DAC and get a Schiit amp. Thoughts?

    hey mike, about this: “Between the HD650 and the HD600, the last and most significant difference is how the HD650 has a better capacity for a more superior and more three dimensional soundstage.”

    Do you think I can get that result via Burson? I think I’ll try the Senn route someday, and I wonder which one (600 or 650) that will suit me more (unfortunetly I neveer A/Bing both of them directly), prefer something that allrounder (from techno, RnB, jazz, instrument, acoustic, pop, rock)

      The Burson has a good soundstage, but if you really want to hear the HD650 presenting a killer soundstage then you’ll have to go up to the $2K tube amps which I suppose you don’t want to do.
      The HD600 is more forward but the soundstage is pretty flat, even with the big amps. This is where the HD650 wins. I think both headphones would be a pretty good all rounder except for perhaps techno (they tend to have super-bright recordings) and the really2 fast rock stuff. Otherwise, RnB, Jazz, Acoustic, Pop, are all good.

      I think you should go for the HD650 for those, it’ll definitely be better with those genres. The HD650 wouldn’t have a problem with violin passages even the fast ones.

    Hi Mike, this is perhaps a different type of question regarding headphones.  I only use headphones for watching Blu ray, DVD and internet streaming music (Pandora, Slacker).  I drive the headphone with a Yamaha Adventage HT receiver.  I am really looking for a headphone that will give me the best possible listening experience and currently looking at the Beyerdynamic DT990, Sennheiser HD600, 650.
    Currently I am using an AKG 240Studio, which does a good job, but I think I can get better…….??     Any help you give is very much appreciated.      Thanks,  Roger

      Hi Roger,
      Each of the different brands have their own sound. You can try the HD650 and see if you like the Senn sound. In my opinion the Beyer DT990 is not too good for music, as it is very resolving of the recording quality.

    So how would a pair of HD 580 Precisions with the HD600 grills and HD650 cables do in comparison to the HD 600 and the HD 650 themselves?  I’ve seen the Precisions go for as low as $50 these days on places like eBay, so wonder if it would be worth it.

      Hi Chris,
      The HD580 + upgrades would be pretty much equal with the HD600. I personally would keep the cable stock. The HD650’s cable pairs better with the HD650’s driver.
      The HD650 remains different than the 580/600 combo, as I’ve explained on the review.

      Yes, since the drivers are better in the first place. However entry level gear make it harder to notice the difference, whereas with higher end gear the differences become more pronounced.

        with something like yulong or audinst, will the constricted soundstage or veil on hd650 ( hd650’s problem when it’s feeded with bad source/amp ) will gone?

        • Reply November 29, 2011

          Mike

          That’s not so easy to answer.

          I think the problem with the so-called “veil” and “constricted soundstage” on the HD650 lies more on the fact that people are not used to the dark sound signature. People often quote headphones like Grados and/or Stax as being more detailed and having a better soundstage than the Senn while the fact is it is not. Grados and Staxes have a more open sound, but their actual soundstage presentation is very bad and likewise their level of detail. But the way Grados and Staxes are voiced makes it easier for people to perceive detail compared to the dark HD650, hence the impressions that we’ve been hearing about the HD650.
          Back to the Yulong or Audinst question. It would primarily depend on the listener. If he/she is not used to the dark signature, then I don’t think the Yulong or the Audinst can do much. What a lot of people are really expecting out of the HD650 is for the sound to be brighter, and to get that they’ll be better off getting some silver cable, or adding 3dB across the treble frequencies on Itunes.

         I was wondering what is the cheapest Amp option that would get that 3 Dimension effect with the 650’s.  Thanks.  I just was listening to the HD600 and really enjoyed hearing some that extra dimension of detail.  Although with rumors of HD700 on the rise I might wait but still I’m interested in what you think or have experienced.

          To me the HD650 bass has more weight, I sold the HD600 because of that and because it was a bit more aggressive. I prefer the laid back HD650. If you want a brighter HD650 maybe the Senns arent for you, but you could get a neutral or brighter ss amp and a silver cable. Have you ever heard the Beyers? That’s a completely different sound

    Greetings Mike,
    I’m on a quest to buy some headphones and reading your review was a great help.
    My choices were down to the HD650 and the AKG K701… but i made up my mind on the Sennheiser’s.
    My next quest is amplification and i would very much appreciate it if you could give me some advice.
    My taste in music go all round, i listen to all types of music… but, and correct me if i’m wrong, fast pace music like hard rock, heavy metal, etc, etc is the type of music that is more troublesome to the HD650… so i would like you to help me choose a amp that would make the HD650 “behave” with that fast music.
    The amp is to be connected to a Sound Blaster X-Fi Titanium.
    In my readings on your site i have seen you mention the Ortofon HD-Q7 and the Matrix M-Stage… will one of these two make the HD650 “behave” with fast heavy music? If so which one would you advice me? …or maybe some other amp on the same price range of those two…
    Thank you so much for your time, and keep up the great work… love http://www.headfonia.com

        Using the Sound Blaster X-Fi Titanium as source and using the RCA inputs on the Ortofon HD-Q7 will it be laugh enough ? Or will i have to use the higher gain mini-jack input on the Ortofon HD-Q7 ?

        After reading your enthusiastic words on the JDSLabs CmoyBB and the PA2V2 I wonder how they compare to the several times more expensive Ortofon HD-Q7 when paired with the HD650… it’s a completely different league ? 🙂

        Again thank you very much for your time.

I seem to remember Mike writing that the HD 600 cable sounded better to him than the HD 650 cable and was wondering what cable you would recommend for the HD 600 – apart from the stock cable – so that neutrality is preserved and sound quality is maximally increased.

The precision, impact and pure enjoyment of the sound that comes out of them is undeniable. What’s particularly interesting is the far more expensive (and better looking) HD 800’s simply don’t hold a candle to the fun of the 650’s. Where the 800’s are clinical, the 650’s are like an addictive drug that you can’t ever get enough of.

                    This is Senn’s opportunity to bridge the gap between the 2 existing flagship headphones and if they want to sell many many more units, they need to look at fixing the ‘issues’ of the 800 by looking to the strength of 650’s. I think the much more palatable (though still steep) price point of the 700’s is the perfect ‘spot’ in which to create a set of cans that’s nowhere near as clinical (read: bland) as the 800’s with the punch, warmth and lovability of the 650’s. They should be looking at targeting 650 owners such as myself with an offer that tempts us to ‘upgrade’ to an even better sounding version of our existing phones. The difference between the 650 and 800 is vast because the 800’s try too hard to be accurate and technically proficient. The 650’s are far from perfect but are nonetheless superior to most other headphones and far more likeable too. Here’s hoping the 700’s hit that sweet spot with superior audio and off the charts satisfaction rating!

                    When do you get your post production set to test? Dying to know if they tune the bass properly! 🙂

                      I still don’t have a schedule for the production HD700 set, but honestly speaking (and I’m a bit sad to say this).. they may be able to add a little more bass quantity, but it’s probably going to be difficult to match the impact of the HD650.
                      I don’t know what Senn did on the 650, but outside of the 580/600 I don’t think I’ve ever heard any other headphones that does bass impact like the 650. They really did something right there.

                      Yep! It’s like they installed a tiny sub in the ear cups. It doesn’t overwhelm you with bass like the boomy Dr Dre’s but you literally feel the bass as if it’s coming out of a quality subwoofer that gives a full and rounded sound to everything you hear.

But I have a good memory, and I have the Shure 1840 and Philips L1 here now, and while the Shure has no useful output below 30 hz, the L1 (with bass reduction ON) not only has that, but has a solid and strong output all the way down. It has to be at least as good or better than HD800 bass. So what I’m wondering is whether anyone can be more specific or detailed about the bottom of the range of the 700/800/600/650, and relate that to the 1840 and L1 possibly, just to get a more accurate picture of how these compare in the deepest bass.

                      Dale,
                      I personally have never compared those headphones A-B-C-D with a focus on the 30hz frequency. I think what matters is first the overall sound signature, and second how the overall bass impact is perceived to be.

                      Overall bass impact works for me. But it gets lost, the comparison that is, unless it’s revisited every so often. So many posts, so much to read….

                      It’s worth noting that while we say “they”, in reality, it could be a completely different team doing the 700/800 as did the 650. The guy or guys who did the bass response design for the 650 may now be designing for Philips or AT – who knows ? In fact, software billionaire and sports team owner Mark Cuban once said that it makes more sense to bet on sports teams than to buy stocks of companies, because the sports teams always tell you when a key player leaves, while companies never tell you anything about their key employees…

              I’ve been in a discussion on Amazon with a 700 owner, and I get the sense that they are really special, kinda like what Mike described in the original review. So not something I would regard as an upgrade to the 650, but something that’s worth the $1000 asking price.

    I been coming back to this review on and off for several months – and i finally took the plunge with the HD 600s — listening to them at work with my “mobile” setup (macbook, audirvana plus (direct / integer) & async Nuforce uDac II). Impressed big time with the sound – heh really no comparisons with the PX 100-IIs.

    Can’t wait to get home and try them with the Schitt combo – Bifrost / Asgard.

    Finally – actually brought the HD 600s through one of the click through ads on this site – Gimmedigi – and managed to get free shipping / a 100 SGD plus savings. So a good experience all round.

      The word on the street (and Mike and L’s word from previous comments) is that both are good for classical, but, given the proper amplification (Crack, Pan Am, LF 339, WA6, etc…) the HD650 makes magic with classical. One of the best, if not the best headphone for it. Ask me in two or three years and I am sure I will agree.

              Plainly asking which amp sounds better than which other really doesn’t help, as it all boils down to the desired sound. I have no experience with the EF5 but plainly speaking, Trent has already answered your question. You get okayish synergy with SS and SS-Tube hybrids, but truly shines with tube amps.

    So, my HD650’s arrived today, and I think they will be going right back. I plugged them into my ipod expecting this amazing sound you guys had been talking about, and it just wasn’t there. It was dark and veiled with no life. Truly overrated.

    Ok, all joking aside, I was actually surprised at how good it sounded coming out of my ipod. I was expecting it to be completely unlistenable, but it didn’t sound bad. Not ideal by any means, but not a complete wreck. I am looking forward to running this one up the food chain. I have been waiting for these phones for a long time…

      I finally got some replacement stock tubes for the LF339 (Cause one of my stock input tubes was defective), which inspired me to listen to the HD650 again despite just recently acquiring the HD800. Ah man, I must say I truly missed them… They sound SO musical and smooth that it’s ridiculous. The HD800 are better on technicalities, but the HD650s will always hold a spot in my collection due to its uniquely pleasant sound signature that no other headphone can quite reproduce in the same fashion.

          I prefer HD700’s (most likely not out at time of review?) to the above but rating something on that level is utterly unfair as some (like myself) love Sennheiser and some love Audeze and nothing can change a persons preferred sound therefore it is impossible to rate one ahead without using your ear as the guide which goes to your brain which may like a different sound (also the Orpheus, although not as accurate has a very lovable and pricey sound that warms the heart even if technically inferior to HD800’s or even cheaper sets in statistical tests).

            But it does get more complicated when the Sennheiser ‘house sound’ makes a move toward dark and lush, like the 600/650 difference. The physical fit usually gets relegated to the background, but it’s critically important too.

                      “improvement” is a subjective term. Let it be a more likeable sound signature or just more detail is what we deem to be “improvements”. If you like your HD600 to sound more HD650 like, then RCA 6AS7G is the choice, a very bassy tube. If you prefer more detailed and cleaner sound, the Tung Sol 5998.

    I recently picked up a pair of HD600’s for use with WA7 fireflies, using the electro harmonix valves, and i didn’t find there to be very much bass impact at all. Is that just a result of the pairing? I found a small adjustment in my eq around 64hz and a small trim at 4k helped. I love the detail but it just isn’t very immersive.

    • Reply January 4, 2014

      My guess not having both of those (but having had the 600) is you’ve matched a slightly soft headphone to a slightly soft amp. I’d guess a headphone with a more crispy sound would be a better match.

          From what I read here the Alpha Dogs are exciting to a lot of people, but don’t have the full bandwidth quality of the LCD2, which I guess you wouldn’t expect anyway. If I could, I’d get all of those ortho/planar mods just to have them. I first learned about the WA7 from the amazing review by Ken Rockwell. Still, I wouldn’t be inclined to drive an LCD2 from a small valve amp, even though Rockwell says it has a great power reserve. Solid state maybe, or a valve amp designed specifically for big planars. What I would choose myself would be a Beyer Tesla. That razor-sharp detail would be a good match for the WA7.

            thanks for the feedback..i can tell you that even on lo-gain , i can’t pho past 2 o’clock with my hd600; way too loud and not comfortable at all. I usually use high gain and hang out between 10-12 o’clock depending on the recording. Other than that, i have found that careful use of the eq to trim out some sibilance around 4k really improves all of the lower freq. response.

            I would sooner cut off my right arm than claim a review by Ken Rockwell is amazing, let alone valuable, notable or informative–it reads more tabloid like than anything else I have encountered in audiophilia. Many of his reviews are poorly written and are totally off the mark from what products actually are like.

            As for his Woo Audio WA7 review, I took a look at it just for the heck of it and I noticed so many inconsistencies in his terminology for audio, some being highly outdated (kc for kilocycles, for example, instead of KHz) and others never used in that context. The measurements themselves are far from impressive compared to a Objective 2 or a Benchmark DAC1 or DAC2’s frequency response, total harmonic distortion and channel balance performance levels. See and compare: http://nwavguy.blogspot.com/2011/07/o2-headphone-amp.html ; http://kenrockwell.com/audio/woo/wa7.htm

            I do not know who or what Ken Rockwell is or what his real intentions are with reviews like these but he is far from transparent and forthright in his practices. I respectfully accept the idea of subjectivity and preference but in speaking objectively of cold hard facts, there is no room for variance from widely established scientific evidence.

              Ken Rockwell is a peculiar personality, but he’s as honest as the day is long, and I’d rather cut off my own arm than misrepresent what he is. He got very famous, especially on two large photo forums, when he published the article Your Camera Doesn’t Matter. There are analogies to that article in audiophilia – the endless and expensive pursuit of one disappointment after another, by a lot of hapless customers who can’t afford it. I wouldn’t vouch for his judgements of sound any more than I would vouch for Innerfidelity’s opinions or those of other similar testing sites. But on Ken Rockwell’s side, take a long look at his printed test measurements of gear – he’s the real deal, and I doubt there’s anyone who has better electronic testing skills.

                I did take a long look and his conclusions were very much off the mark based on the numbers he obtained. His numbers are much worse than those in the Objective 2 and the Benchmark DAC series, as seen in the very links to NWAVGuy’s site whose results have been repeatedly verified and hold water to this day. Lest you believe an unhampered monetary pursuit for audio perfection is what I am a proponent of, which I am not (personally, I have not and will never spend over $500 on headphones and I only own two headphones at a time, one of them costing $100 or less), I am quick to point out that the Objective 2 is available for a totally economical $150 or less, less than half of the price of the $399 Woo Audio WA7, and performs decidedly better according to the numbers, and personal experience.
                As for his photography… I’ll just say that his photographs have major color, brightness and contrast balance issues and that is just being mildly descriptive of the clear issues in them. Yes, I have heard from photography experts before, and many of my friends are gifted photography majors at a prestigious university, that his ideas are akin to quack medicine–it is all psychological feel good and not real scientific, well-measured technique and skill. It is a good thing magazine covers and billboards do not use his photography techniques or we would be stepping several decades backward.

                  2. Ken’s article that I referenced had nothing to do with his personal photography. It had to do with everyone’s ability to explore their own creativity. I found it to be a breath of fresh air among so many stagnant discussions.
                  3. I’m happy that you’re happy with your headphone and amplifier purchases, and I wish you well.

                    Dale, I wager you have not looked at the numbers I specifically mentioned. I do not like being superfluous when it is entirely unnecessary but here it goes, cutting to the chase:

                    You mention Rockwell’s numbers are dead accurate. That is okay and that is not what I am questioning. It is his interpretation of those numbers that are off the mark. See these numbers for THD, channel separation and frequency response. They are taken directly from the linked articles by NWAVGuy and Rockwell. The more you know, the more you grow:

                    Woo Audio WA7
                    THD at 1 KHz, 37 ohms: 0.0111652% (A clear disadvantage by about a factor of 10. This is CMOY level performance.)

                    Frequency response: 3 dB down at 12 Hz (A built-in low-pass filter, I see. Jokes aside, this is way too much deviation for a product of this price range. A CMoy could easily outpace this.)

                    Channel Balance: 1 dB (See worst case scenario separation in the charts. It is not outright detectable, but this much imbalance does skew sound to one side to some degree. As a recall from some readings regarding psychoacoustics, it is on the order of 10 to 20 degrees off-center. No, thank you for that much cash.)

                    Output impedance (for kicks): ~22, ~35 and ~108 ohms (By the 1/8th rule, headphones below 168 ohms cannot even be used on this without some response changes. Forget IEMs which are finicky as all get it and can vary by +/- 5 dB or more from this. As for that 108 ohm output, that might as well be saved for the very rare vintage headphone that under perform most $20 modern headphones anyway.)

                    Objective 2
                    THD at 1 KHz, 15 and 150 Ohms: 0.0023% and 0.0016%

                    Frequency response: +/- 0.1 dB from 20 Hz to 20 KHz

                    Channel balance: 0.6 dB

                    Output impedance: 0.54 ohms
                    (These ensure no audible distortion, soundstage skewing, and the widest possible headphone compatability.)

                    I hope this helps clarify any confusion or misunderstanding. If this doesn’t make sense, some Google-Fu action can help you. In short, the Woo Audio WA7 isn’t all it’s cracked up to be. If you are buying based on the numbers, it easily falls behind. I believe even many of the FiiO’s surpass it on technical level. That is not to say a tube amp is bad. If you enjoy the sound, then I guess go ahead and spend the quid. However, I would submit that many would rather experience the purest beat and emotion the artist intended and save the stash of cash for a better pair of headphones or, better yet, music than spend extra for a substandard premier amp.
