The New Superluxes Are Good! The HD330, HD440, and the HD660.

superlux_hd330_440_660_05

THE HD330 & HD660
The HD330 and the HD660 are tuned to be the forward and agressive sounding headphones. They can be likened to a Grado, except that the fundamentally different driver and housing design keeps them relatively different from a typical Grado. I actually like the Superlux rendition better, as the forward character is not accompanied by the typical harsh treble you get from a Grado. I still have an Alessandro MS-Pro that I keep for yesterday’s sake, and even on a soft-treble amp like the Zana Deux, I still have problems adjusting to the treble of the Grado-made driver. But these Superluxes are different. Take the usual standard of Superlux headphone drivers (which is excellent for the price), and tune them to be forward, engaging, and fun with punchy bass. Say hello to the best Rock headphones under $100.

Forward mids, slightly agressive treble, tight punchy midbass. I really can’t find fault with these cans. Not to mention me rediscovering Muse with the presentation that the HD330 and the HD660 is giving. PRaT is really happening with these two. And although I think the warmer and more laid-back HD440 is the better all-rounder for different genres, the HD330 and the HD660 are the sound that fits me better.

Between the HD330 and the HD660, there are slight differences. The HD330 is semi open, and although it gives a better open and airy feel than the HD660, the result is a slightly looser midbass which drops the pace of the headphone down a little. The HD330 is also slightly warmer, a tad more relaxed in presentation, and also a tad more relaxed in treble. I personally don’t like compromised presentations, and so the HD660 will be the one I use for Rock. But on the other hand, I can also see the merit in the HD330, as it would be a little less extreme, and would probably have a wider genre bandwith.

Intellectual property breach on the housing design for sure. The HD330 is semi open and leaks sound a little bit. The HD660 is fully closed.

 

COMPARISONS
Of course I got curious, and given all these PRaTs, I went and compared it to the HD25-1. At 300 Ohms, the HD330 and the HD660 are a little harder to drive, and though they do well out of a JDSLabs Cmoy or a Yulong U100, the HD330 & HD660 is slightly above your Ipod’s capacity. So that’s one score for the HD25-1: easier to drive. Well, the HD25-1 did what it did best, and soon enough I found out that the bass punch, the focus and the energy is still better transferred through the HD25-1. The smaller housing of the HD25-1 is probably giving it an unfair advantage here, but on the other hand, the HD25-1 sounds more claustrophobic due to its “signature” small soundstage. The HD660 and the HD330, on the other hand, has a more proper soundstage, the size of your average full size cans. Other plus and minuses considered, the HD660 certainly shines as it beats the HD25-1’s $200 pricetag by a few hundred percent. Of course, given the Beyer DT770-like housing, it would be impractical to take these headphones out as a portable, so in that sense the HD25-1 is still a good headphone if you can afford the $200 pricetag.

BUILD QUALITY
The Superluxes should be available for roughly $50, and so don’t expect too much about the build quality. The design for the HD660 and the HD330 clearly borrows from Beyerdynamics DT770, and actually the structure is quite solid, without too much problems during day to day use. It’s only when you take a look at the materials being used that you would understand why these are $50 headphones. Superlux are clearly aware of their market positioning, and opted to use a cheaper grade plastic than what you would find on the Beyerdynamic DT770 or the Sennheiser HD25-1. Not a big deal to me, really, as they give me a great sound for a great price, but I thought I’d mention it to you guys. Additionally, the headband cushion and the pads are made from synthetic leather, and the cheap kind as well. While they are much easier to be cleaned than the verlours you find on the DT770, these pads should have a much shorter lifespan than the verlours on the DT770. (By the way, all these references to the DT770, and no comparison about the sound should hint you that the DT770’s tonality is nothing like the HD660 and the HD330. You can always argue against this, but despite the DT770 PRO’s (250 Ohm) overall superior resolution, but the HD330 and the HD660 are the two headphones that I prefer for Rock. The DT770 PRO has far too a monitoring tonality to it that makes it quite unsuitable for music.)

Single sided coiled cables were great during use. Makes me wonder though, what happens if you put better cables in these headphones?

 

END WORDS
I started the draft for this review because of the HD440. In my experience, the previous Superluxes had an awesome technicalities, but always fail on two factors: sharp treble, and lack of mid body. The HD668B was the least prone of this factor, and paired with a nice warm amp like a plain Cmoy, becomes quite a musical headphone with respectable technicalities. The HD440, however, breaks the old Superlux trend of “monitoring headphone” tonality, and is the first Superlux to have a good and musical midrange suitable for music listening.

During the course of auditioning time for this review, I’m drawn more to the HD330 and the HD660’s presentation. It’s fun and forward, yet without the harshness of Grados. And although the HD25-1 still wins in absolute PRaT, the HD330 and HD660’s more spacious soundstage makes it better in some ways than the HD25-1. Between the HD330 and the HD660, again I am leaning toward the HD660, but the good thing about Superlux is that you don’t have to pay twice the amount of money for twice an increase in model number (In fact, the HD660, the HD440, and the HD330, all should retail for close to $50). If you think that the HD668B was great, then you’ve got to listen to these new Superluxes. The only music where the HD668B is better is for classical symphonies, but everything else should be better on the HD330, HD440, and HD660.

Special thanks to Drys for the Superlux loaners.

      They’re all nice, but I have personal bias for the HD660. Think a slightly less punchy HD25-1, but without the $200 pricetag, AND without the claustrophobic soundstage.

      I haven’t heard the AD300, only the AD700. The soundstage can’t be compared, the HD330 has an average full size soundstage. It’s a good soundstage, but it still can’t be compared to the AD700. The AD700 is very open and spacious, but it lack bass. I would guess that the AD300 somehow takes on the same traits of the AD700, 900, and even AD1000.

      They are quite more comfortable than the HD668B, but the HD440 is a little more softer and more comfortable than the HD330-HD660.

    The HD-660, 330 & 440 are the Older Tenlux manufactured headphones, I liked my HD-660 but you always have to press them to your ears to hear the beauty of them and that is just to much work, for us with a non godzilla head, and after receiving the HD-662F in the studio… it not only blows the 660 away in sound but the isolation and contort and fit along with the thick pads, will make the HD-662F a studio standard. I see no use to consider the older models… (i sold all my old stock and used ones on eBay) when you have the like’s of the much better isolation and sound of the Closed Ear HD-662F, also try the darker HD-669 sure to please bass freaks.

      How does the 662-F compares to the 669 ? I have the 669 and it’s seriously lacking midrange, highs are a bit aggressive and lows are not so punchy. Still pretty for the price range.

        The 669 darkens with age in a good way, it is deep and dark, older music like Weather Report sound great thru these cans, EQ wise this can is Fat.. not muddy, both have good isolation The HD-662F has that perfect natural sound and bass, and not lacking midrange at all, this can is a studio favorite, a non removable cable, i can’t imagine anyone who has spent time with this can not like it, to me this is the standard to judge all others… and most can’t touch the perfect balance the HD-662F exhibits.

      I think the issue here is the HD-662F and other monitoring series not possesing enough mids for music listening. If talking from a strictly technical standpoint, yes the monitoring are better.

      Btw I dont think the HD660 needs to be pressed in for the sound to work, nor does a bunch of other people who has tried it.

        Hi have you ever owned a pair of HD-662F? the mid’s shine and an-amazing natural balance from high to low. i would expect someone who put a pair on for the first time to say these are midrange focused… Also sorry i was misunderstood but i did not say you had to press the 660 to your ears for sound to work… but does not fit tight against my ears, and have to press them to hear the lovely low end the can exhibits… and I have went thru more cans in the studio and artists have brought there own high dollar cans in, to track with… and with drummers they need to hear… when i ask them to take their 660 or whatever fancy brand they are using off and try the HD-662F they smile and stop complaining.

        i just posted a 2 part testimonial on the HD-662F so don’t take my word just trying to help.. i already know it is the best closed can for the money… and the listing pleasure is beyond words.

          I listened to the HD662F and it’s just a variant of the HD662 and the HD662B sound. One bright, one dark, one in the middle. I think the 662 or the 662F was the bright one, where the HD662B is the bassier one. All of them exhibit the same problem for music listening though. Not enough mids and too sharp trebles.

          Glad you’re enjoying the HD662F.

            Thanks for your take on the 662 series, the only one i have spent time with is the F, i have found all the newer series Superlux models i have listen to have vast different EQ curves. would be nice to hear from other 662f users… still can’t imagine listening to a can with more mid’s maybe more extreme highs… here is a PDF of the 662 series for anyone interested in comparison’s… it likens the F to similar EQ as SRH440.

              I think it will make an excellent studio headphone, but not so much for music listening. I am just talking from previous experiences. Perhaps all headphones that was designed for monitoring uses are not that great when it comes to music listening, regardless of brands. Sony, Shure, Beyer, etc, etc.

            Not enough mids and too sharp trebles?
            are we listen to the same can, hd-662f? I doubt. IMO, it sounds well-balanced in highs, mids, lows, accurately,
            transparency,
            and
            meanwhile
            also very musically, especially for classic, new age and chill out. In fact, I just use the hd-662f to listen all kind of music now, and ditched all other brands’. However, it is understandable that everyone has his own
            different
            likes on sounding
            characteristics. by the way, I don’t use any fancy instrument to drive hd-662f. Mostly, use the Onkyo Tx-8011. But, I found any equipment service it well also, even cheap MP3 Player.

      Hi Daniel,
      the HD440 is much better then the Sennheiser HD-202 or the total mud HD-205, the 404 fits your ears good and good sound quality… use to use a pair on the drum kit, exterior wise they are cheeper in build like the $59 AKG, you can crank the drivers on the 440 and they take it and stay clean… sound wise good solid cans, destroy cans such as the harsh cheep EP.3070 these 440’s when i was getting them were higher priced then the 330, but i never got great reviews or feedback from them as i do the HD-662F and other models. but of course the 662F are in a class 10 times any of the above.

          Hey Man,  not sure the Senn, u are referring to, but the 205 are “out” for me they distort under volume. like drinking bad beer and the 202 is a solid 20$ can if thats all you can afford but it’s no 662F in any shape or form…  move up to a HD-280 or up for comparable sound.  personally out of the 440 330 or 660 , the 440 too cheep build resonates i have no use for it.. the 660 is a good can i can see why anyone would dig it…  I sold mine when the new ones came out. the 662F is better for critical listening in loud environments at extreme volumes.  and out of the 3 their is no drastic EQ difference as with the 681, 662, 668B, or 669 that is Eq similar to the 280.  that is my grain of salt for what it is worth.  AudioHipster

    The Superlux HD660 have a very long burn in time. Some filter wool damping makes the bass tighter and less sibilances. I use Beyerdynamic DT770 Velour pads, and they will sound much better and will be more comfortable.I really like the speed and midbass, perfect for travelling because they are undestructable.
    I think there is definetly no breach in the law about the design.Its obvious AKG, Beyerdynamics, Sony- they buy O.E,M plastic housings from Superlux.

    perhaps HD660 or HD 330 can give me a better sound.
    will it be a good replacement for my M2?

      Why aren’t you happy with the M2? I need some information otherwise I can’t give a blind recommendation.

        what i dont like with the M2 :
        – soundstage
        – a little to harsh
        – high freq a little unnatural.

        thanks for your reply and sorry for my bad english

            maybe hd330 will be great ( it is semi open right )
            sorry for making you confuse lol
            what do you think about the sound sig  between hd330 and m2 ? 
            it is almost first time for me using headphone/IEM ,
            usually I’m listening to a pair of bookshelf.
            And i don’t like IEM which sound just like the singer sing in my head, i need a cans that sound just like the singer in front of me and the instrument laid behind the singer , just like a speaker does.
            thanks a lot mike 🙂

              I would like to answer your question but it’s still too vague.

              There are a lot of headphones where you can get good separation between the singer and the instruments. It depends on how open sounding you want to get, but at the end headphones can never be as open as a pair of speakers.

              Briefly from the top of my head, the Superlux HD660 and the Sennheiser HD598 both have a good soundstage imaging and should give you that singer – instruments separation. Some IEMs like the Etymotics ER4P or the JH5Pro also does a very good job of separating the singer to the instruments.

              Oh, and the speaker doesn’t separate the singer-instrument. It’s in the recording.

    Hello Mike.Thanks for the nice review

    You sort of put in the same sentence the Superlux HD660 and Sennheiser HD598 in a comment about soundstage. To what extent can they be compared? 

    I mean, I listened to the 598 in a shop and I really loved it, detailed but lively and fun, with present enough but not overshadowing bass. I preffered them over the Beyer DT770 which I found too harsh in the highs. Next to the 598 the Audio technica m 50 seemed really bad, muffled sound and not enough refined. 

    Given all that, what should I expect from the Superlux HD660? I m a bit skeptical cause they are so cheap but you praise them so much. To what   “below 200$” dac/amp can they be paired with to reveal their best?  

    I mainly listen to indie rock and IDM music such as Flying Lotus like bands. Sorry for the bad english, this is not my mother tongue

    • Reply September 14, 2011

      Okay, not so easy to answer this one.

      Briefly, the HD660 is dryer, less liquid, less laid back, less smooth than the Sennheiser. Bass is tighter, however, and punchier and the Sennheiser. It is a closed design, and so although the soundstage imaging is very good on the ‘lux, it won’t feel as open as the Senn. It’s a bit similar to the Beyerdynamic DT770 in a way, though it’s not quite as trebly, but it’s fairly close.

      The Senn HD598 is a smoother and more refined phone. It’s very liquid, semi-laid back (though vocal presence is very good), but on the other hand it’s also mellower than the ‘lux, and for fast rock music the ‘lux will do a better job.

      The Lux is not going to sound as muffled as the M-50 (though I won’t describe the M-50 as muffled, but I understand why you say that), and also not going to sound as harsh as the DT770. The Lux can’t quite match the DT770’s resolution though and that’s where the DT770 has an advantage for monitoring and some music such as classical. The Lux also can’t quite match the M-50’s black background and superior instrument separation.

      So what I’m saying is, between the phones you have compared to, there are plus and minuses. But certainly at the price that they’re selling
      for, the Lux is very very good. It won’t be as smooth as the HD598, but
      for indie rock I may like the Lux better than the HD598. I *may*.

      As for the DAC-amp..
      The Audinst AMP-HP would match well to improve the bass and punch of the
      HD660.
      The Audinst HUD-MX1 would match well to improve the soundstage and
      midrange of the HD660.
      The Asgard Schiit would match well to improve the overall sound quality
      of the HD660.

        I would have to agree with mike as i also find a similarity in the differences between the DT880 vs HD668B. If you have never own any high end headphone before you should not be able to notice much and as it only cost about 10% or less of the (depending on where you get it) high end model it is a fair tradeoff. Most of the time I still prefer to use the HD668B as a universal headphone when compared to the DT880 eventhough it is more refine and smoother with the DT880

        O wow you rock ! it s more than I was hoping for, cheers! 

        I think I ll go for the HD660 or his semi open lux equivalent paired with one of the 2 last amps you talked about. Indeed there is no point buying the 598 if I have to wait another month before being able to get a decent amp. I ll buy them later and actually I guess it s good to have spare cans especially with this headband problem on some sennheisers.

              Okay, I don’t remember about the DT770M. But from experience, different pads will always change the tonal balance, since the pads is a big part of the overall acoustic chamber. So i wouldn’t call it an improvement. Velour tend to add treble where leather tend to add bass. If the change happens to suit your needs then yes it would sound like an improvement. But seriously, it’s easier to get that perfect tonal balance with Itunes’ Equalizer.

    based on your opinion above the 660 was just better than 668b is that right? btw im going to pair it up with my schiit asgard.

      Please make sure that you understand the points of the comparison, and from what factors the HD660 was considered to be “better”. So don’t take it blindly as being “better”.

      I think the treble of these Superluxes are more crisp than the K701. The K701 is smoother.

    hi. great review. 
    i wanna buy a HD660 but i’ve read that open headphones have always a better sound of close ones.
    so i don’t know if is better for me the HD668b.

    -you wrote this about HD 668b

    [quote]You can feel that there is a sense of space. Free, spacious, but the sound image is correct; it doesn’t exaggerate the music’s particular space. If the artist performed in a closed venue, then you will hear his/her voice echoing, while if the artist performed in a large, open venue, then you can hear him/her perform on the stage with his accompanying band personnels on their respective positions, his/her voice traveling through the open air, and you can tell which clapping and/or cheering audience is closer to the stage, and which ones are farther. It doesn’t sound crowded, everything is well-put, where they are supposed to belong.[/quote]

    -what about the sense of space whit the HD660?

    -I don’t know if the HD660 is very convenient, whit the polster pads of dt770 it costs 60€.
    The dt-770 pro 250ohm costs 120€, but the built quality is better.

    -is the Hd 660 suitable for large head? and Hd 668b?

    ps:sorry for my English.

      Hi sorry for missing your comment. 

      The part you quoted actually was written by another writer, Dhani, not me, but anyway
      the sense of space is not as open sounding with the HD660, but the way instruments are laid up are actually more accurate on the HD660. 

      Regarding the HD660 vs DT770:
      “As for the HD660 to DT770, they are very close sounding, but the HD660 has a more forward & engaging vocal which I find to be good. Driver resolution and refinement is not quite up to the DT770 range though. ”

    Hi.. thanks for your review.

    which one of these would you recommend? HD668b, HD660 or HD330?
    I want to use it for music , games and movies.  I know that the HD668b has a wide soundstage but i didnt like the design and reviews seems to be leaning towards HD660. But i worried that it would not give a proper soundstage and surround since it is a ‘close back’ headphone.

    People also talk about Hd660 sound quality to be equally match to beyerdynamic dt770 and sometimes dt990. Is that true? If that is true, would the HD330 be equal to DT880 since it is also semi open headphone?

    Please help me decide. I am very new to the headphone world and anymore researching is just making me more confuse.

    Thanks!!

      Sorry for missing your comment earlier. 

      I don’t think you’d find the HD660’s soundstage to be bad, as actually the soundstage imaging, how it layers the instruments around, is better than the HD668B — although yes you’d still get the closed headphone sensation which the HD668B doesn’t have. 

      As for the HD660 to DT770, they are very close sounding, but the HD660 has a more forward & engaging vocal which I find to be good. Driver resolution and refinement is not quite up to the DT770 range though. 

      The HD330 however is a little different than the DT880-990 and in this case you can’t just say that because they’re both semi-open then they would be similar. 

      I think the HD660 is my #1 choice for music games and movies. Although bass quantity and impact may not be sufficient for movies. But again you can’t have a headphone that does it all.

      Well usually distortions happen when the music is bass-heavy, and the music he posted aren’t exactly bass-heavy (I mean it’s Elvis?). So perhaps it’s just a case of a defective unit, and as he mentioned the problem is gone after he got a replacement unit.

    Hi Mike,
    I’m considering between the HD 661 and 660 – I’ve seen previous comments about how the 660 is slightly better technically. However, I don’t have a reference point because I have never heard both of them.
    I’ve only auditioned the Beyer DT880, Hifiman HE6 and I own a pair of Audio Technica AD500.
    Is it possible to describe (just briefly) the HD661 and 660 might sound more like any of these headphones?
    I’m more interested in the balance (low, mids, highs), clarity, separation, soundstage and overall tonality.

    I really appreciate it if you could help me out as I can’t audition the Superluxes – I have to buy them to get them.

    Hey there Mike, your reviews caught me when I was looking for reviews for the Superlux headphones, particularly HD660 and HD661.

    I am wondering which of those does better at ballad/female vocals, basically all slow-paced songs. I like bright headphones with tight, punchy but quantitatively low(not overwhelming) bass and I wouldn’t like the mid to be too thick.

    Do you like the 660 or 661 more? Looking forward to your review on HD661.

      Hi ChunHoe,
      Normally, my friends who listen to slow paced, ballad female vocals pick the HD440 as their favorite. The mids are nice, full bodied and tube like, but being clear enough so you won’t find it to be too thick. However the bass is a bit loose though it is not a boomy or bassy headphone.
      The HD661 is a portable and in the general scheme of things it is a less capable headphone than the HD660-440-330.

        Hi Mike, thanks for your reply.

        I’m actually quite different as I prefer bass-light headphones, as much as I like them in pop rock, it gives me a headache after some time. What I always have on my priority list – clarity, detail, crisp sound and if possible a wider soundstage. Seems like it’s wrong to compare it to HD661?

        If what I read from reviews is correct, the HD668b is also close to what I want too, right? How does that compare to HD660?

          ChunHoe,
          Yes the HD661 is a smaller, portable headphone so it’s quite different than the HD660 (despite the number).
          The HD668B is semi open I think. And its sound signature falls in line to what I refer to as the Superlux monitoring line.
          As I wrote in the article:
          “Now, one of the reasons that I still hold back from making a wide recommendation of the Superlux headphones is that their tuning are mainly geared toward professional monitoring uses. From the HD662 to the HD669, all boasts great clarity and instrument separation, but mostly they have been too bright and too thin on the midrange section for good music listening purposes. Not so with these new generation Superluxes. The HD330, HD440, and the HD660 still boasts the same clear sound that you get on the other Superlux models, but with a tonal balance more suited for music listening.”

      The HD660 is smoother and less harsh, though still upfront but not as much as the Grados.

    Hey Mike! Thanks I got my HD660 today after testing between it and other superluxes.
    It’s really good, especially after I pair it with a Hifiman EF5 with a CD player as source. It can surprisingly scale very well with good amping and sources!
    I am quite surprised it is only for about RM150 (about 50USD). It can outclass most other entry-level headphones even from major brands such as Senn, Beyer and Shure.
    Thanks for the recommendation!

    Hi mike. the differences between HD660 and HD330 are only in the external part of the cup?

      I actually have never opened them, so I wouldn’t know if they use different drivers. But judging from the way they sound, I think the drivers are the same on all three models just different acoustics from the shape of the cup.

      The Grado sound remains unique, and I think it’ll always have some fans. So in that sense it’s hard to really say absolutely that the HD660 is best. However on the technical standpoint, the HD660 is better, while still having a very good signature for Rock.

      I will agree with him, I had the SR60 and they were fatiguing after a while. Also they will leak like mad so people will hear you as if you have two speakers attached to your head and ambient noise will creep into your listening. These have more bass without an amp, i will say save your money for a higher end Grado and check those it, that’s what i’m going to do, even then they might not be keepers.

    Hi. After researching around a bit, I think I’ll be getting HD330 (more laid back and semi-open design). But one thing that is deterring me from getting it which is the 150 ohm impedance on the headphone. Will it perform well with the onboard audio? (Planning to get the DACs and the amps one by one.)

      Hi Emiya,
      I really can’t say if your onboard audio will be able to do a good job with it. Perhaps add in something like the Fiio E10? http://www.headfonia.com/the-latest-must-have-the-fiio-e10-usb-dacamp/

          The E6 with the HD330? It would probably have enough volume, but I don’t think it can do a good enough job. The HD330 will be better off with something like the E11.

    Hi there Mike! Very nice review of the new slux models! 🙂

    I really am confused which to buy from HD330, 660, and 668B. I usually listen to Gospel RnB, Alternative, Jazz, and Classical.

    The reason I’m torn apart from choosing is that I’d also like to have a cMoyBB headphone amp. The thing is, the configuration for 668B is 1x9V w/ lower gain; and for HD330 and 660 is 2x9V because of its 150 ohms impedance. So basically, I have to choose only one configuration for the cMoyBB and choose from 668b or from either 330 and 660.

    Please help me, thanks a lot! 🙂

      Oh by the way, I really am siding more with 668B because of the wiring features included in it. I can just replace the wires if it broke!

          Yes it’s 150 ohms, but 150 ohms are not that difficult to drive. I would go for the E11, but as I’ve said it’s not too difficult and it’s not too picky about amplifier pairings.

            Hi Mike, I recently got the HD440 based on your review (thank you). Seems like it sounds much better when plugged to my laptop than my iPhone 3Gs (even when its amped).

            Interesting that you mentioned E11 because thats what I decided to take. When I paired it with E11, it gives a ‘warmer’ sound, improving the bass (EQ1) and rolling off the treble highs, making it more easy listening to an already ‘bright’ sounding cans. Even with the roll offs, it is still ‘clear’ sounding. I think I could have done well with Cmoy BB too.I did find the mids in HD440 to be slightly too ‘laid back’ for my taste though. The vocal took a step than I would have liked. I would prefer the ”sweet and full midrange’ to come closer/forward to me, making it more intimate, focusing on the ‘sweet and full midrange’ that you talk about :)From my research, I believe there is an amp that can help me fix that – GoVibe Mini Box amp. Do you have any other recommendations?

            Cheers

              Good description.. the HD440 is funny in that the vocals are indeed laid back, even though the mids are full (I think I mentioned that on the review?). I don’t think an amp would change that presentation.

      Yes you are right. I think HD440 does have better SQ: much clearer trebles and better bass compared to MDR-570’s more relaxed, warm, soft, muffled sound. But for the crucial presentation, I guess I just need to rant that part out.

      Oh, and I already received the GVMB amp – its just a simple and clean amp. So you are also right about not being able to change the presentation. Sigh..

      Maybe someone else would appreciate the laid back presentation more than I do. But I hope the guys from Superlux are reading this and take into consideration.

      Putting my rant aside, they deserve a lot of credit and have done a great job on price : sound quality ratio. I hope they continue what they do and come out with a HD441 (or something) that puts Jamie Cullum ON the stage, the way I think it’s meant to be 🙂

          Mike, this is getting interesting.. I think the HD440 is revealing different things to me now.. Or at least I am seeing it in a different way..

          I never saw it this way before but now I am starting to imagine Andy McKee playing ON stage and me being seated back on the 10-15th row from the auditorium stage (depending on your volume). Sometimes, depending on the song, I could imagine myself standing just a few rows from the concert stage.

          Basically, I think the midrange that is presented from the back creates this hollowness (or empty space of air in between) which creates this imaging depth.When I visualize it this way, the ‘confusing’ headphone start to make more sense, in a 3D way. I never expect myself to say this, but.. cool 🙂 But of course, the soundstage is not as wide as ATH-AD700 but didn’t you prefer depth over width when it comes to 3D imaging?At first I doubted this, so I started playing more ‘Live’ recordings and it really seems to fit in! Even studio recordings can work but the depth is reduced, but it is definitely still ‘there’. Haha..I’m not sure it if would work for all types of songs, and I suppose it largely depends on how the source was recorded. But now I can’t help but laugh at myself 😀

            That’s correct, the depth in the soundstage is good on the HD440. With the HD660 you get just as good depth but more accurate imaging. The AD700 just feel spacious but there is no real depth in the soundstage.

    How’s hd440 and hd 660’s bass amount,extension and impact comparing to say m50 and srh440,840?

    • Reply April 27, 2012

      Mike

      The HD440 is not so big on bass. Not bass light but rather lacks impact. 

      The HD660 is more fun in terms of bass. It doesn’t have a lot of quantity, but punches fast, tight and the impact is good. The pace of the bass is faster than the M-50 and the SRH840, tighter, but less quantity than both those headphones. If you’ve heard the HD25-1 bass, the HD660 is quite like that.

        Thanks for the comparison, Mike!

        I guess the superluxes are brighter comparing to than three of them.

        Something unrelated to sound.
        How comfortable are them? I have a big head and ear,always have problem with shallow earcups. Are they deeper than m50? And do you have problem finding their replacement pads?

        • Reply April 30, 2012

          Mike

          I really haven’t use them enough to need replacement pads, but as for the fit.. they are quite comfortable. They press less than the M-50 and the cups (at least the 330-440-660) are deeper than the M-50. The M-50’s pleather is a better quality than the ones used in the Superluxes, so plus and minuses.

    Hello Mike,
    Is it absolutely necessary to get an amp if I want to enjoy the HD660.
    Or should I just opt for the HD669 or HD440 instead of spending money on the amp?
    Cos I’m in a tight budget here. 🙁

    Thanks for the advice. 🙂

    I’ve just received my HD660 in the mail and been doing some A/B comparisons with some of my favorite rock headphones using a Burson amp. In short, it’s good. Fast with a good amount of tightly controlled bass. The mids are nice and upfront, while the highs are also nicely prominent.

    The Beyerdynamic DT1350 and AIAIAI Tracks are my #1, #2 for rock. The HD660 hold its own with both of them. The HD660 is fast, like the Tracks, but the DT1350 is faster and with smoother, more upfront mids. The bass on the HD660 is more upfront than the DT1350, beating the DT1350 in volume and punch. But the Tracks’
    bass is deeper and punchier than both. The Tracks’ recessed mids and narrow
    soundstage hold it back, which is not surprising being an ultra portable. Where
    the Tracks and DT1350 absolutely slay the HD660 is resolution at higher
    frequencies. Cymbals sound life-like through the Tracks and DT1350, in
    everything from classic Yes to Hendrix to Nine Inch Nails. The HD660 have some
    brightness to them but are slightly choppy at higher frequencies, missing out
    on detail the Tracks and DT1350 happily provide. One thing the HD660 does
    better than both is having better tonal balance. And maybe a wider soundstage.

    Fit-wise, the HD660 barely fits my melon-sized head, at even maxed out
    capacity. The Beyerdynamics DT770/880/990 headphones are much larger and oodles
    more comfortable. I must admit the DT770’s velour pads do add comfort to the
    HD660, making them easier to wear for long sessions.

    Other headphones I’ve tried for rock: AKG K181DJ (too much bass), M-Audio
    Q40 (great with neutral amp), V-Moda M80 (good but not enough sparkle), Fidelio
    L1 (mids too recessed to the point vocals sound distant), HD25-1-II (ditto), HD650
    (good for slower stuff), HD5000 (ditto), Grado SR225 (too much sparkle), Shure
    SRH940 (ditto X 100).

    Mike you’re review is really nice, but I’m still confused! Which Superlux do you recommend for PRODUCING rock music, so monitoring instruments AND record vocals without sound leaking? I was thinking about the 668B for a long time but than I realized that for clear vocal recordings a closed headphone would be a better choice. So I started to read about the 669, as it’s basically considered to be the closed version of the 668B. But there are just a few reviews about it, and I couldn’t decide. Could you please point out the main differences between the HD-669 and the HD-660?

        Thanks for the fast reply, it’s really good that you keep answering in this thread! Then what about the HD662 (normal, B or F)? Some people say HD662F is the best Superlux for studio purposes. I’m really getting confused, everybody say something else. I would be happy if I could also just enjoy my music with the headphone AND use it for recordings, but of course I know I cannot get everything with just one can. So my preference is studio work, how does the 662 stack up against the 669?

        • Reply June 6, 2012

          Mike

          I’ve never really compared the two directly, Buda. The 662 would also be good for studio mixing, but the HD669 may be the better one of the two.

        I am mainly a classical man, as you know, but I didn’t want to stop listening to rock once I plugged it in. Surprisingly non-harsh in the treble, too. I don’t listen to any music that is THAT fast, so I didn’t think it would make a huge difference. I was wonderfully wrong. Even though it is a bit tricky to get in the USA, still very much worth the price. Thanks for this review!

        I’ve bought the HD330 for 27 € now. After a short listening session my impression is as follows:

        Comfort:

        * the inner diamter of the original pads are to small for me, so the the phones are kind of semi-supra-aural and not comfortable at all.

        * the pressure on the ears is a bit high, but everything can be bend, because it’s made of metal

        Sound:

        * I did not like the sound of the original pads. It seems to be a bit bassy/boomy and not very balanced. Still the sound is bett than what I would have expected from a 27 € headphone.

        * After 5 minutes I’ve changed to the Beyer genuine leather ear pads. IMHO the sound is much clearer and less boomy now, a big step forward. Also the comfort inreases _a lot_!
