High End Earbuds Review -updated-

GENERAL COMPARISONS WITH IN-EARS
In the old days, one of the thing that people constantly praise the PK-1 for is its soundstage, though now I’ve discovered that the MX980 and the TM-5 are also pretty phenomenal with the soundstage. The earphones can really make you forget that you’re only wearing a tiny earbud. They won’t give you the precise, dead black background, and vast soundstage that you get from IEMs such as the JH16Pro, or even the Etymotic ER4. But some impressions between the PK-1 and some IEMs have generally favored the PK-1 in terms of soundstage performance. I think the loose fit of the earbuds and the open sound characteristics is mostly what’s attributing to the sense of full-size headphone like soundstage with these earbuds. Having an open sound can sort of trick you into thinking that the soundstage is bigger than it really is. Having an open sound also gives an impression of a more airy sound even for studio recordings. And in this sense, the earbuds presents the listener with a more consistent, spacious sound, whereas a precise but fully sealed IEM like the ER4 or the JH customs more accurately reflect the ambiance as captured in the recording.

In a sense, the earbuds give you a more speaker like presentation in the sense that they are more airy and open sounding. Going back to the JH customs, I can’t help but noticing the closed-in and sealed presentation, despite the huge and much more accurate soundstage. I remember some people friends telling me that they can’t live with the ER4 due to the lack of soundstage, while I’ve always thought that the ER4 has one of the best soundstage presentation around. Again, in this case, the more accurate IEMs becomes a more faithful representation of the recording, in which they give you a closed ambiance when the recording was taken in a fully sealed studio room. The earbuds can never quite give me the zoomed-in, fully engaged presentation of the IEMs, but while they are somewhat “looser” and less accurate in this sense, they do give a generally more open and spacious soundstage irregardless of the recording.

As I was comparing the earbuds to the 8-driver JH16, the question of single versus multi driver arises once more. Speaker guys are always on this sort of discussions, one full range driver versus multi driver speaker set ups. As with full size headphones which mostly comes with one driver per side, the earbuds does present the music with a greater sense of coherence which is the signature of full-range speakers. They may not handle each frequency as well as with a multi-driver IEM, but the sense of coherence in the frequency range is indeed very present.

AMPING REQUIREMENTS
One thing that I’ve heard many times with the PK-1 is that you need a good amplifier to really hear what it’s capable of. For most mainstream recording that tend to be mastered at a higher volume level, I find that the Ipod is powerful enough to blast it to volume levels that make my ears hurt. So, in that sense, the gain level is quite sufficient, and I also don’t think that the current demands of these earbuds to be something so high than an Ipod can’t handle.

When I move to a good portable amplifier like the Pico Slim, ALO Rx, or SR-71a, obviously the sound is improved. In that sense the PK-1 is no different than any other headphone or even portables that I’ve tried. Given a good driver quality, even headphones like the PX100 and the V-Jays improve with amplification. Among the three, I do find that the PK-1, the HR-1 and the Blox TM-5 to improve the most with quality amplification, while I’ll be happy to use the MX980 and the A8 right out of an Ipod (as it’s also easier to drive than the Blox or the PK-1).

I’ve tried the earphones with many different amplifiers, up to the Burson HA-160D and the Grace m902, just to see how well they scale. I’d probably say that a good portable amplifier is good enough for these buds, with the Pico Slim being my favorite amp for pairing with the Yuin and the Blox.

END WORDS
The Yuin PK1 is a legendary earbud, and I do think that its sonic performance clearly deserves the legendary performance. However, I don’t think it’s quite fitting to be the “King of Earbuds”, in a way that it’s one earbud to rule them all kind of thing. Perhaps the lack of low bass and PRaT is its biggest weakness, as it simply doesn’t do rock well enough. As it is, the Yuin makes for the best jazz, vocal (especially with an RSA Mustang), and acoustics earbuds among the three.

The Blox’s tuning is fitting for a totally different genre than the Yuin, and is excellent for rock, electronic, and I also enjoyed it for classical as it just gives the best soundstage performance of the three and a proper weight and slam that’s very important in symphonies.

The Sennheiser MX980 is less of a specialist than the previous two. It doesn’t have the midrange of the Yuin or the Bass of the Blox. But in a way it also has the widest genre bandwith, and is the best all-rounder of the three. It’s not dark like the Blox, and it’s also a better bass performer than the Yuin.

For most people, the $200 pricetag of these generic looking black earbuds would probably sound like a big ripoff price. Even the cable build looks no different from the generic $5 earbuds that you can get on electronic stores. They simply don’t inspire too much confidence in them. The Sennheiser simply is much superior in terms of build quality, employing fancy materials, even up to the inline volume control. For some reason, however, I doubt if the looks and build quality will really direct the purchases toward the Sennheiser. I think the cult surrounding earphones are quite niche by itself, and people who decides to put $200 into an earbud would probably be basing their purchase based on the sonic credentials.


Update: Addition of the Bang & Olufsen A8 and Crossroads HR-1

BANG & OLUFSEN A8
The A8 from Bang & Olufsen is normally not considered an audiophile option by the headphone crowd. It’s been in the market for a few years now, and yet the stylish A8 has never joined the rank of “legendary” earbuds such as the Yuin PK-1 or the Crossroads HR-1. Since a unit was sent to me by Anton, I thought it’ll be good to include it in the comparison just to see where things stand.

The sound is quite likable, and the tonal balance is quite good, bearing more similarities to the MX980 and the PK1, rather than the extremely warm HR-1 or the dark sounding TM-5. I can see how the mainstream crowd will be able to appreciated the A8 due to its clean sound and forward signature. The midrange area is consistently forward, regardless of the recording, and it becomes a signature character of the A8. This can be nice at times, but also often time the midrange, especially upper mids can be overly forward for pop or rock recordings, and I can’t help but having to listen to the A8 at a lower volume level. The sound is very clean and grainless, something that I don’t find on the other buds. I’m not talking clarity or transparency here, but rather the lack of grain in the sound that gives a very clear impression of the sound. For this reason the A8 doesn’t quite need to boost the treble levels to give an impression of clarity, and in fact, the treble levels is quite okay for a majority of different recordings (though the upper mid isn’t, as I mentioned earlier).

One of the most noticeable deficiencies of the A8 is that I don’t a linear enough frequency curve at the upper treble and lower bass ends. Making a comparison with the MX980, for instance, the Sennheiser have more low bass presence that “completes” the lower end body, and also the same on the upper frequencies which gives you the cymbal crashes, the air and the ambiance in the music.

Although the A8 boasts a forward midrange, it doesn’t have the sweetness of the PK1 or even the MX980. The mids also sound congested often times, and is not as well articulated as the PK1 or the MX980. The overall instrument separation and soundstage size on the A8 are also not as good as on the MX980 and the PK1. Finally, the timbre is a little off when you compared it to the MX980, PK1, and the TM5, and it’s very noticeable once you start playing live instrument recordings.

I can say that the A8 is actually pretty well developed, if you consider that B&O was probably targeting the product for the average consumer base. The solid build quality is definitely the best in this comparison, and really puts all the other chinese offering to shame. The solid rubber-wrapped metal hanger and the modern minimalistic design is a very strong plus on the A8. And finally, the A8’s well balanced and grainless sound does a good job of giving the average Joe a small taste of what a proper hi-fi sound would be like.

The Bang and Olufsen A8 has the best build quality and design. The hanger is also a plus, as it keeps the buds in place securely.

The adjustment range of the hanger, and also notice that the vertical rod can be pulled in and out as well.

CROSSROADS HR-1
From what I’ve heard, the now discontinued Crossroads HR-1 is quite legendary in the earbuds circle. And somehow, due to its being discontinued and there aren’t a lot of HR-1 around, it has somewhat earned a higher legendary status than the Yuin PK-1.

Upon receiving the HR-1 from Anton, I noticed that the housing has an identical shape, notches and holes with the Yuin PK-1. Most very probably the two comes from the same OEM company in China. The HR-1, however is finished in a nicer glossy paint which looks good compared to the flat-black Yuin. There is also an addition of a red and blue marking for easier identification of the right and left side. The cable is a soft multi-braid cable similar to the Westone cables, and is much softer and flexible than the PK-1’s. At the end of the cable, the HR-1 is terminated with an angled 3.5mm jack, again this is more user-friendly than the straight jack of the PK-1.

The voice is somewhat similar to the PK-1 that I really believe the two were manufactured by the same company, but with a different spec on the driver, cable, and perhaps also the housing. The tonal balance, however, is quite different than the PK-1, as the HR-1 is significantly more mids oriented and warmer sounding than the PK-1. Treble presence has been attenuated quite significantly on the HR-1, resulting in an almost never offensive treble, regardless of the recording quality. I can see that the HR-1 is an attempt to tune the PK-1 sound in a way that it would blend well with the majority of treble happy recordings these days.

I think the super-warm and treble attenuation of the HR-1 is quite controversial. For one, I find the HR-1 to be the most demanding of a good amplifier compared to all the other buds in this comparison, even the PK-1. Unamped and direct from a portable player, the sound is muffled and very unimpressive technically. However, when plugged in to a good portable amp, in this case I’m using the Pico Slim, the HR-1 transform itself quite tremendously. The soundstage becomes very big and comparable to the size of the PK-1 soundstage, amped. For some reason, perhaps due to the mid-centric tonality of the HR-1, the soundstage have an impression of being deeper than the PK-1’s soundstage. Also, the midrange opens up considerably, and the detail on the treble and the low bass also improves. There tonal balance is still the same mid-centric sound as if unamped, but I don’t find the HR-1 to be muffled or muddy as I did when unamped.

So the HR-1 transforms to a totally different earphone when properly amped. But the tonal balance is still the same, and most people will need to re-adjust their ears to be able to appreciate the HR-1’s sound. What I truly like about the HR-1 is how the treble always remains unoffensive on many different recordings, but the extreme colorations make it hard for me to recommend it to people, unless I know them to be a fan of a mid-centric presentation.

The Crossroads HR-1. The housing body looks very similar to the Yuin PK-1, but with better finishing quality. The foam pads are a bit tattered on this HR-1.

    Right after I published this article, I received a package containing the Bang & Olufsen A8 and the legendary Crossroads HR-1 earbuds from Anton. Looks like an update is due sometimes in the future to include the two additional buds. 😀

      I reckon you'd find the B&O A8 to have an extremely wide soundstage for a pair of earbuds, though may be slightly shy on bass compared to the Yuin series. The Crossroad HR-1, however…. *chuckles* I guess it'd be up to you to see if you'd like it though. Personally I find it to have a slight tinge of strange warmth throughout the entire spectrum.

      Haha. Let me continue reading your review ya Mike. Great writeup there. 🙂

        Thanks for the heads up! I need to spend sometime with both earbuds, as they're totally new to me. But it's all good since I can be doing that while working on the portable amplifier shootout, and the Yulong U100 and Musiland 02 reviews. 🙂

          Haha.. I reckon you know who I am ya Mike. Pardon me for my email address with its vulgar wordings though.

          Mike, how would you rate the comfort for the earbuds though? From my experience, the generic casings used for the Blox TM5 and Yuins in fact do contribute to a better comfort, generally more acceptable for the masses. I am not too sure about the MX980 though, I've heard some complaints about the earpiece being too big and heavy. How would your experience with them reflect this aspect though? 🙂

          The MX980 do look good though. Smexy. Haha. I was once tempted to grab it, but honestly, the volume control and perceived ergonomics turned me off a little. I have the MX580 however, nice pair of cheap earbuds, mids are quite forward and sweet, making it very emotional for vocal-centric songs, but other than that, the Yuin PK3 still reigns… In my humble opinion. 🙂

            No dude, I actually don't know how you are, and I can't remember any email resembling what you said. o.0

            Yes, the TM5 and the PK1 are more comfortable, but on my rather large ears, the MX980 holds better. It's also heavier, but I don't think I have any problems with it. I think the weight of the rod is probably pulling down on the housing in such a way that makes it sit better on the ears than the PK1 and the TM5.

              I should really try out the MX980 one day.. Sadly, I can't get to audit them anywhere in my country, so most probably I might need to order it to try it out. I still find the design abit of a turn off on comfort for me though (I'm a puny asian with no eyes and small ears, hahaha), but I shall reserve further comments until I have them on my ears. 🙂

                Interesting that you decided to take on the MX980 and not the Blox. I don't know, but I have a feeling that people who're into Yuins are probably not going to be impressed at the Senn. The different character of the two buds tell me they're targeted for different type of music.

                  Oh, honestly I am not too decided yet. Either the ZePhone NB01 (they say it uses the same driver as the PK1, but different cable and plug, they also have an upgraded version of the NB01 as well which has different cables than the stock NB01), Sennheiser MX980 or wait for the Blox TM5 I reckon. Or a Yuin OK1. Haha. I guess I'll just sit down and enjoy my Yuin PK1 first.. Since I can't seem to decide on which to go for, as honestly, I am expecting my next earbud purchase to be better than the PK1 instead of a sidestep to it.

                  Decisions decisions, we rant when we don't have money, and we rant when we are deciding on how to spend money. Oh the irony! 😛

        Been spending some time with the HR-1, and my impression is that the HR-1 is an even warmer version of the PK1. It's also less bright and has better mids and bass body than the PK1. I can see how some people would prefer the HR-1 than the PK1. The two has an identical housing though! It's like Jaben ordered it from the same OEM company, painted the HR-1 gloss black while the PK1 is matt black.

        -corrected the TM-5 part-

          Hmm.. I find that excessive warmth may sound weird sometimes, probably that's why I mentioned it has that tinge of warmth which made me shy away from it. Doesn't seem to "fit in" right. Haha. But hey, I have to say, the Crossroad HR2 and HR1 do look great, with braided cables and that special coating (said to be some sort of UV coating) which helps avoid scratches on the earbud's body themselves.

            Yes the braided cables are great, looks like Westone cable knock offs. It is very warm and mid centric though. Good for female vocals.

      The IE8 has good bass, but it's not as articulate as the TM-5. PRaT is also not as good as the TM-5. The IE8 has a smoother sound, more relaxed, where the TM-5 still has a good pace and attack.

      It's like comparing the sound signature of a HD650 to an LCD-2. Both dark, both good bass, but different voicing.

    How about Atomic Floyd AirJax?
    And does the Radius HP-TWF11K count as an earbud or in-ear?

      I've tried the Atomic Floyd AirJax before. Honestly, not very impressed with it for the price. Don't get me wrong though, it does sound good, however abit too costly for what it delivers. 🙂 Its sound signature reminds me best of the likes of Philips, made quite bright to seemingly bring out its details, bass extension which isn't too deep or wide, vocals just a slight bit thin. Overall does sound pretty nice with mainstream songs, but for the price.. I'd hesitate over buying it.

      The Radius is definitely an in ear. 😀

    @CccC: what are your top 3 earbuds? have you tried ATH CM700??

    • Reply January 27, 2011

      CccC

      Whoops, sorry, I didn't try the CM700.. Yet. *chuckles* But I had a fairly decent discussion with an online buddy of mine over how the CM707 (a supposed replacement for the CM700). The soundstage, mids and highs of the CM707 are done pretty well, albeit with the soundstage being wider than deeper. Bass, however, is abit on the lean side. This goes very smilar with previous impressions of the CM700 as well.

      I have either owned or heard (I don't have that much experience with earbuds too, sadly) the Yuin PK1/2/3, Atomic Floyd AirJax, Sennheiser MX580 and MX400, Crossroad HR1/2, Bang&Olufsen A8, Final Audio Piano Forte II, and I've discussed and talked about the ATH-CM707, Blox TM5, Sennheiser MX880/980, ZePhone NB01, Yuin OK1/2/3 and some other.

      My top two is the Yuin PK3 and Yuin PK1. Nothing to slot in the 3rd at the moment, and I am looking around for one to outperform either the PK3 and PK1 in my ranks.

      Yuin PK3 for its tremendous value for performance factor, not to mention is scales very well with amplification for something this small and cheap. Manages to push out INCREDIBLY deep and low bass for its size and price, far deeper than the PK2 (PK2 has bigger bass though), capable of going as low as the PK1 even. It's very much like an unrefined, mini version of the Yuin PK1.
      Yuin PK1 for an overall balanced sound with a hint of warmth to it, making it sweet for gentle acoustic songs and vocals as female vocals and Jpop stand for a huge part in my music collection. For me it's hard to point on the fault of the PK1, unless I am listening to rock or extremely fast paced songs where it'll start sounding fairly congested and messy.

      One more thing I have to tell you about myself, I am a sucker for comfort. *chuckles* Up till now I've avoided the higher end series of the Sennheiser MX series (880 and 980) due to the presence of a volume control and their ergonomics, the volume control adding an extra bulk on the cable and the MX980 seems rather uncomfortable to me, but it won't stop me from trying them out before I decide if this stands true or not. I adored the generic case shell that Yuin used and hence they could stay for ages in my ears. Oh not to mention I actually sleep with my earbuds on (music helps me sleep :P), so I'd be rolling over on my side, where I would need earbuds that doesn't press too much against my ears, which explains why I don't use IEMs, or any earbuds with built on earhooks.

      Well, so much about me, what would YOU wish your future pair of earbuds to do, a_tumiwa? 🙂 For starters, you may consider the Yuin PK3, far more balanced and acceptable to a wider range of listeners than the Yuin PK2. 🙂

      Definitely. The soundstage is surprisingly very deep. I suppose you can count that as good technicalities, yes. Everytime I go back to the Blox after listening to the other earphones, I get blown away by the soundstage. It's not even close.

          I really don\’t know. Driver quality, somehow? Also combined with housing design? I know that Sennheiser vastly improved the soundstage from HD555 to HD558 just by changing the housing. I\’m not talking just a more \”open\” sound improvement either. But from having no depth to a real good depth in the soundstage.

      The Koss KDE250 isn’t technically an “earbud”, I call it an open earphone. But it sounds very, very good. It lags behind the Sennheiser MX985 in absolute clarity (but only just), and the fit is really fussy to keep it in the sweet spot where the best sound is. I haven’t heard the TM5, but don’t be fooled by its lowest frequency response being rated as 40hz: the Koss has far and away the best bass out of any open earphones I’ve ever heard. It will SLAM in the low end like only much larger headphones can!

      I think of it as sharing a sound signature with the PortaPro, but greatly refined. It doesn’t lose entire frequencies like the PP, and it will give you far more detail and clarity.

      The KDE250 is criminally underrated in hifi circles.

    Mike, how would you compare these high-end earbuds and ultra portables like V-Jays in terms of soundstage and overall SQ? It’s very hard these days to find an open headphones that remain truly portable and do not require additional amplification. I was looking for an improvement over my V-Jays in terms of bass and detail rendering and unfortunately had to move to closed cans from Shure. The sound quality is fine, with much better details and bass, but I’m lacking the airy sound and portability of the V-Jays and I’m wondering if these Senns or Blox could be considered as a solution for my problem.

      That is a very good question.

      I don’t think the ultra portables have the refinement, treble mid quality of the PK1, bass quality of the Blox, or the soundstage of the PK1 or the Blox. But given the larger driver size, they can produce more bass quantity very easily.

    I own Yuin PK-1, OK1, Sennheiser MX980 and Blox TM5 2nd batch.
    I can say that the best are MX980 because they really sounds as big cans.
    TM5 bass is not as good as the one in the review. They are only more ‘bass biased’ than MX980 and PK-1 with deafult signature but if you plug an equalizer and crank up the bass only the MX980 really sound good.

    After starting my headphone journey with IEMs and went through many dozens of them, now I’m going back to basic finding a sweet spot with the PK2! Earbuds seems to be the best compromise for my listening at school as the lack of noise isolation is now a plus… It was a nightmare trying to insert/reinsert the SHURE E500 with it’s triple flange! However… back at home the HE5 still reigns : )

    I’m waiting impatiently for the revisions as I’m very very interested in the A8! I love the design and of course the brand’s heritage… I’ve always wanted to try one but was always put off by the rather high retail price… while buying second hand is out of option… so many AAAAAAAAAAA fakes!

          I’ve used the PK1 without an amp, with an iPod Shuffle 4th Generation. 🙂 Mike also wrote a good deal about it in his review. It will still go up to a ear tearing volume, and the basic characteristic is there- sounds smooth, warm, generally balanced.

          It’s just not as refined as how it would be as amped – more deep bass, better high extension, wider and deeper soundstage. 🙂

          Yes, I don’t think you can make that generalization with IEMs. Like what
          I’ve written on the article, the impression of a full size headphone is
          partly from the earbuds’ open sound presentation — where IEMs are more
          closed in due to the seal. However, technicalities wise, the BA multi
          drivers are currently the king of the game. That doesn’t mean that the
          multi driver BA is the best way to go, as there are other parameters to
          judge audio performance by.

          On our local forum we are discussing the merits of multi driver BA vs
          single driver DD, and each have their own followers depending on
          preferences and music choices.

    Do you think there’s any IEMs that may best the Yuin PK1 in terms of overall sound quality? I know it might be hard to beat, especially with how spacious and airy earbuds sound, but I’d love to give it a shot, especially that we can hardly find any other earbuds better than the Yuin PK1. And I don’t really intend to buy a sidestep earbud this time (another earbud with a different sonic signature).

    Was considering customs, such as the ACS T1.. But that’d be of last resort. Will definitely prefer universals so my fiancee can grab them off from me whenever she feels like it. Haha.

      The closest to the Yuin is probably the EX1000. Being an IEM, it won’t
      give you an open sound like the PK1, but it would better the PK1 in most
      other areas, simply because of superior driver.

      The customs, at least the few models I listened to, sound nothing like
      the PK1. You need to stick with single dynamic driver to get close to
      the PK1 sound. Multiple BAs sound different.

      • Reply April 27, 2011

        CccC

        Hmmm.. When you say sounding nothing like the PK1, you meant by sonic characteristics? I haven’t been into IEMs long enough to learn about the differences in sound of (multiple) BA and dynamic drivers.

        I guess IEMs not being able to sound as spacious/open as earbuds is simply unfortunate for me though. *chuckles*

          Well, I probably need to write a good article about dynamics vs BA one
          day, but simply put, dynamics have their own characteristics, and so do
          BAs. In the world of speakers tuning multiple drivers to sound as
          coherent as a single driver is always a challenge, and some argues that
          you can never make a multiple driver sound like a single driver.
          Likewise the discussion with single driver dynamics (PK1, EX1000) vs
          multi driver BAs (dual drivers to JH16s.)

            Oh. Indeed. I had a shot on the JH (with universal tips), TF10 and some others when I was over at a retail store at my place, they do sound good.. But for some reason I find them a little too technical sounding for my liking.. For some reason everything doesn’t sound coherent to me, it sounds like the highs are there because they sound be there, the lows are there because they should be there, but not because of a uniformity that creates something musically pleasant to my ears.

            But it might just be me, Mike. And truth been told, I haven’t spend enough time on them yet regardless. Just a couple minutes and I’m done. Maybe I’m just took picky for my own good. 😛

          Additionally,
          Though I agree that the earbuds have a more open sound (compared to say
          a JH16), I don’t think the open sound is an actual soundstage image. The
          actual soundstage image of a good IEM (again, the JH16) is much bigger,
          but the sound is very closed due to the seal.

    Which one of these would be perfect amp to make  the Pk1 (150 ohm impedance) sound better  without any quality degradation.

    A) Fiio E10.(0.3 Ohm output impedance hence damping factor of 500)
    B) Dacport(10 ohm output impedance hence damping factor of 15)

    i have been listening to the PK1 this whole week and i think the sound signature really suits me.
    I have HD650 and need an amp. What amp do you recommend if i want to have PK1 like sound?
    Or maybe i should get HE-500? Because if i am not mistaken, HE-500 paired with HM810 sounds like PK1 CMIIW.

      The HD650 is quite different than the PK1, I don’t think amplifier choices will make it sound like a PK1. The HE-500 perhaps is closer in sound signature to the PK1. I would pair it with something like the Graham Slee Solo.

    I would like to thank you very much for an extremely helpful article. I want to confirm that Sennheiser MX-980 are really very neutral and provide a very good imaging, separation and soundstage width for the price (and considering earbuds’s inferior technical abilities to IEMs). I personally enhance transparency and depth using my StageDAC’s crossfeed circuit which works brilliantly. Pairing them with my Torpedo tube amplifier (with impedance switch), these are buttery-smooth but still very neutral.

    Comfort is the factor that forced me to move from full-size headphones (HD800). I am considering IEMs as wel but I’ve had issue in the past with the fact that you have to push them into your ear canal. You definitely get a greater comfort and softer feeling with earbuds and that’s why I decided to purchase these.

    For 140USD new, these are a great value if you appreciate earbuds and want to get much better soundstage and separation in comparison to typical cheap pairs.

    Hi, great article! I’m considering getting a pair of earbuds to compliment my Grado RS1i – specifically, I hope to kill two birds with one stone: something more portable and something which will work better with classical music (I’m thinking specifically small-scale choral works and string ensembles, neither of which respond well to the Grado’s treble emphasis).

    Do you have any thoughts as to which of these may be most suitable? Or any other related thoughts?

    I’m also considering IEMs, but aside from not being so keen on complete isolation I also imagine I would have to spend significantly more to get a decently-balanced and open sound (I may of course be completely wrong).

      You need to decide, based on your research, whether you’d like just the earbuds that sit in your outer ear, or whether you want IEMs that insert into your ear canals.
