Superlux HD 668B: A Giant Killer?

Not to be mistaken with the Swedish home appliance manufacturer, Superlux is a Taiwanese company specializing in microphones, speakers, and headphones catering to a wide variety of customers, from casual music listeners to professional artists. However, despite their professional-oriented market, Superlux managed to sell their products at very competitive prices. One fine example would be the Superlux HD 668B studio monitoring headphones, which costs only $30.

Studio monitoring headphones. For $30. Did I just say $30?

Styled like an Audio Technica-AKG hybrid, the HD668B is very well-made. Its plastic body is finished in matte black, solid and smooth, with no jagged edges or uneven seams. Synthetic leather is found on the headband pads and big earpads, which feels very supple, and excellently stitched. Clamping force is just enough to keep the whole thing from moving around, but not so hard to induce dizziness and/or fatigue usually associated with over-clamping headphones. Isolation is quite good, although being a semi-open headphone, it won’t give an isolation that’s as good as a closed-back headphone. Also, the Superlux HD 668B comes with a detachable straight cable, which is slightly thicker than a Logitech computer mice’s cable, and terminated with a gold-plated plug. Just by looking at and holding it, you wouldn’t believe it is priced at $30.

      Hey, actually Dhani wrote that one. HD668B is really good sounding. Detail, clarity, punchy bass. Typical monitoring sound.

      In terms of refinement, the AD700 and HD595 is still better. But the HD668B does some things better than those two. It really is a great buy for the price (~$30).

    Thanks so much for bringing headphone users information about the Superlux HD668B. I still can't believe these are not talked about more often elsewhere.

    I have tried Sennheiser HD600, Koss ESP/950, Denon AH-D5000, and AKG K701. (All fully broken in!) I am not embarrassed to say that I believe my 668B sounds more natural, accurate, as detailed and most of all the most enjoyable of all these. Truly astonishing headphones, regardless of price.

    A word about breaking in the 668B: I have found they do need about 200 – 300 hours before the bass/midrange transition balances out and what fine grain there is, dissipates.

    Thanks again, Mike!

    • Reply July 8, 2010

      Hi Roth, yea the HD668B are truly great.
      Although I don't think it has the class and refinement to compete with the HD600, Koss ESP950, K701, but perhaps the 668B strikes a wonderful synergy with your music and amplifier.

      Glad you enjoy it. I think one of the main reason that we don't see more people with HD668Bs is the limited distribution. They're not a very common headphone.

      • Reply July 9, 2010

        Roth

        Mike,

        I'm running them with an Oppo universal player and SACD's/DVD-A's through a Purity Audio K.I.C.A.S. headphone amp (all-discrete, no op amps).

        Going back and forth between the 668B and K701, I can more easily discern backing vocals in the mix with the 668B, as well as a much better-balanced bass than K701. Also, the 668B sounds more natural in soundstaging and truer to the original recording, to these ears.

        I hear an artificial "cavernous" quality to the K701 that overlays all recordings. The 668B is more chameleon-like in that it doesn't seem to add as much of its own signature. I think a strike against the 668B is its plastic housing does color the bass/lower mids to a small degree. This headphone will definitely lend itself to user modifications.

        Thanks again for the opportunity to spread the word on the Superlux HD668B, Mike.

        As an aside, I am beginning to see more outlets for the 668B, so rarity is less of an issue today.

        • Reply July 9, 2010

          Mike

          Roth,
          That’s a very detailed observation! I don’t have the K701 to compare with the HD668B at the moment, but I can relate to the differences you pointed.

          I think what you said are valid, but I do think that the HD668B still lacks treble refinement compared to the K701, and that the frequency curve is a bit V-shaped. It depends on the recordings that you’re playing as well. Some Chesky recordings, for instance, are very good and also very smooth sounding. On such recordings you’ll find the HD668B to be marvelous. But try playing a regular mainstream recording, and you should hear the difference in refinement level.

          The HD668B is a great headphone for the price, and I’m glad if more people are discovering it. But I still think that it’s not yet at the level to compete with the K701 (though the K701 do have many weaknesses of its own).

  • Reply July 9, 2010

    Bogart

    Why compare these to the K701? I’m more interested in how they stack up against headphones in the $100-$150 range. If they are honestly in the same league as the AD700, K240, MS-1 etc, then they really are a steal.

    • Reply July 9, 2010

      Mike

      I always feel that the AKG K240 is quite flat and boring, even the Sextett version which I had for a while. I definitely prefer the HD668B to the K240.

      The AD700 is quite special with its entry level Audio Technica signature, and although it's not my favorite phone, I think the AD700 is still superior to the HD668B.

      The MS1 (especially the MS1i), is quite special, and again, though not that far ahead the HD668B, I would still rank it above the HD668B.

      Maybe we can plan a $100-$150 open headphone comparison to discuss this in more detail. 🙂

        Mike,

        Any luck rounding up those competitors in the $100 – $150 price bracket for a comparison?

        Now that I have spent more time with the 668B and agree with your assessment they are not in the same class as AKG K701, Denon AH-D500, et al. I will say that they spend more time on my head than those others though, because they are more musically engaging.

        I have done several things to modify the 668B and feel I have raised their performance level quite a bit. Now I listen to only two headphones – my HifiMan HE-5LE and Superlux HD 668B.

    At US$30 HD668B is a steal for a pair of headphones. For this price you surely can't be complaining because the value (price/performance ratio) is far greater than most headphones. However, please note that after this Headfonia review the prices have been climbing for Superlux products.

    The HD668B has a very clear, transparent sound signature, which may tend (a little) to the analytical. Pairing it up with a warmer amp should create better synergy. Personally in my setup it has a tendency towards brightness which is quite different from, say, a Sennheiser, but it's nothing that matching cannot resolve.

    I can see the HD668B gracing the house of many audiophiles. Clarity is quite amazing for its price. I'm sorry I have to sell this as the clamp is too strong for my (relatively large) head.

      Thanks for the input! Haven't been following Superlux prices lately. They are very good and still be worth the price even if they raised it.

      I also agree with what you said in sound, price-performance ratio, and yes the clamp can be a little too strong.

    Great phones. Bought them on business trip to Taiwan for NT2400 = US$70. Cannot fathom why it costs more to buy it here than in the US. Its made by a company based here …??

    Anyhow, used it with my ipod nano 5th gen, and it sounds more professional than my Grado MS1s. Tighter, better defined bass, more air, more space, and more detail. Goes well with classical music (good rips) and has great dynamics.

    Tried it amped once I got back home, sounds even better. The bass is great and the level of transparency and detail trumps the MS1s.

    For US$30, its a no brainer – a total steal. It will give you better music on an amped system with none of the edge of a Grado SR60/80/MS1. For 70 dollars, its still good value.

    Warning – it is a very transparent and neutral-ish cans, as a monitor should be. It adds a little more bass than the best ones, and do not give you a huge soundstage, but its pretty unbeatable once again at the sub US$100 market. Also, if your source material is bad – these cans will not disguise it like a Grado or cheaper Senns, your ears will bleed from over trebley or badly recorded material.

    But use it with a decent CD player (Modified KI signiture) and put it thru a good amp (Modified Accuphase E207) and this thing will make the US$30-50 dollar tag seem ridiculous.

    Finally, if there is one critique, these are not boogey cans. They wont make flat sounding music more bearable. It doesn't give energy to sound. So its prob not the rockers choice. But with jazz, classics, acoustics and vocals, its great.

      Thanks for the comments. I do agree with a lot of the things that you said, and in some areas you described the HD668B better than what Dhani (the author) did. This is why it's good to have informative comments such as yours, because sometimes our writing can be fairly limited, and another point of view will give a better description.

      On a side note, it is quite surprising to hear that the Superlux costs more in Taiwan. Yes it is a Taiwanese brand, and it should be cheaper there. Perhaps you didn't find a good store?

        but headstage is still my first priority, just that sometimes the serious handicap on bass on K702 is making me wanting it more. is HD600 a better choice than 650 if i wanted more LF and still able to listen to orchestra music?

          Mike

          Hi nders,
          Headstage and good bass seem to be two characters that is difficult to get in one package. The K701, the K501, the AD700, for instance all suffer from so-so bass.

          If you want to listen to Orchestra, the HD650 is actually the better choice than the HD600. Of course both the HD600 and HD650 will give better bass performance than the K701. But I don't think you're going to get the K701's headstage with those phones unless you have some serious amplifier at hand.

          I think something like the Ultrasone Pro900 will give you the headstage and the bass that you want. As you know, they do come with the S-Logic feature which is a love/hate thing, but I do think that the Pro900 is one of the best among Ultrasone's line. It should also work well with Orchestra.

    Well, I said I'd sell it…but I didn't. The other day I went for an audio show featuring the HD600 and HD800 with their house amp. Either this is the Sennheiser "sound" or the headphones aren't broken in…I was surprised by how I disliked the Sennheisers, even the HD800. There's little clarity – a warmish kind of sound. Just like how I wasn't impressed by the HD650 at a meet. They sound like hi-fi no doubt, but their balance doesn't compare as well as the Superlux.

    At this price, this is a no-brainer. People are preferring it above the K701. The more I listen to it the more it sounds like I'm listening to the music and not to a headphone.

    Just like to add that all dynamic headphones tend to compress sound a little. There are people who say that a high ohm dynamic headphones tend to compress dynamics a little too much, you need to get the most out it from a high end amp. The Superlux doesn't fall into that category.

    Planar magnetics maybe not so much. Audez'e LCD-2 may my next (and last) ticket. 🙂

    Hi Everybody,
    I am the tech support manager for Avlex Corp. We are the United States distributor for Superlux. I would like to thank everyone for the kind words about the HD668B headphones. I have received numerous requests for these and I thought I’d post here since this seems to be the source of much of the buzz on these cans.
    Unfortunately, due to a major price increase from the factory, we have no plans to bring in any more of these headphones. Things may change, but at this time we are out and I have no dealers left in the US that seem to have any. I was informed that a Canadian company, Paw music, is selling these on line. I called them and they have a small shipment due in February, 2011 but most of that order has already been spoken for.
    It may be worthwhile to get on their back-order list if you are serious about getting these headphones.
    Thanks,

I bought them for £35 with free shipping. The price hasn’t changed either, so what a great deal!

    Hi Mike, Just starting with the bass how does it fare against the sennheiser hd558. I just want a basis of comparison that I am using with me here

    • Reply February 21, 2011

      Briefly, the two headphones are like comparing a Beyer DT880 to the Senn
      HD650. If you’ve heard both, then you know what I’m talking about. The
      Senn would have a looser, smoother, fuller bass. Where the Superlux has
      a dryier, more articulate bass. You’ll also find the Superlux slightly
      thin in the mids, where the Senn is very full on that region. Likewise
      the treble stands out more in the Superlux, where the Senn is more relaxed.

                We’re neighbors bro 🙂 I am at the Philippines. Its $18 shipping for that one to me. That model might be too peaky sounding for me in the highs too. I’m not much into a grado type signature when we are talking about frequencies above the midrange but am open minded with bright headphones as long as the highs are balanced with no peaks. Basically a lean overall sound is fine with me which is why i am willing to try the 668b. I was fine with the k701s bass for example but the peakiness in parts of the upper mids and lower highs bothered me

          the HD668B for a monitoring stance. The HD330 was sort of in-between,
          with a slightly aggressive (ala Grado) upper mids and treble.

      However the AD700 is great with its open and spacious sound. The HD668B feels noticeably more closed than the AD-series.

    I’ve been using SL668B with my Cowon J3 and thought they were great but a little too bright and too claustrophobic. But today I’ve connected them to my Lovely Cube and the result is simply astonishing, the soundstage improved dramatically and bass kicked in. This is the level of SQ I had when paired HD650 with Audinst MX1 (although HD650 with LC are still better in terms of realism and soundstage).

    I would say that pairing the 668B with iPod or similar device will give you only 50% of their potential. The difference on a good amp is dramatic.

      The are not going to sound flat due to the detail level, but you may find them a bit bright and lacking midrange body compared to the PortaPros. The resolution, detail, soundstage, etc will be a big step up from the Portapros though. Another thing to keep in mind is that the HD668 is a full size with a stronger clamping force than the Portapro.
      I don’t guarantee that you will be 100% happy with them, but it wouldn’t hurt to give it a try since they are relatively inexpensive.

      Too bright, too sharp, even for Jazz.

      Though it depends on the Jazz recordings that you listen to though. If you listen to audiophile Jazz recordings then the U100 + 668B combo would be fine. But if you listen to the older Jazz recordings, Miles Davis, Coltrane, etc then I wouldn’t recommend it. For that I’d probably recommend the Schiit Asgard for $250. No DAC though.

          I bet you haven’t tried listening to them together, have you? Well then, let me share my experience with the combo. As far as I’m concerned, it’s just perfect for any kind of instrumental music, no matter the period – even “Kind of Blue” sounds beautiful. The vocals are not bad either, but the sibilants happen to be quite painful (the headphones are not yet burnt in, though). I don’t find them any bright or sharp – the amount of bass is satisfactory and the sound is very detailed but by no means tiring or unplesant.

      Isolation is good, fairly good clamping force, but the circumaural pads design can let sound slip in a little. It does tend to get bright after a while and you would notice that the mids are not as full as you would like them to be for music.

    I bought them for playing games, watching films and listening to music. I found that they have realy not enough mediums (500 – 1.5KHz) and i can t use them at all because of this. The high frequency are also way too high and the very low frequency are not high enough (20-60Hz).

    Here is the frequency shems that comfirm my tought http://www.superlux.com.tw/upload/function.product.info/17f81435-74a5-48b2-af35-202a1d1730b2/resource/br_HD668B_view_en.pdf

        what about on other areas? soundstage, clarity, detail, comfort…
        hd668b or hd660 which one is the best for rock and classical(mostly symphonies, orchestral stuffs)? Are there any good cheap headphones for these genres?

        Can i use these headphones with unamped sansa clip or cowon j3?
        Bass response is not so important for me, im not a bass-head. So,  will hd668 B have too much bass for me?

          Hi Susta,
          I think the HD660 is better for those purposes, and it’s also one of the best cheap headphones for those genres. Keep in mind it’s not going to be a perfect headphone though, they are budget headphones after all.
          As for the amping requirement, yes an amplifier would be recommended. Please check #5 on the FAQ: http://www.headfonia.com/faq/

    I was wondering, does the sound leak out? Since I walk around with headphones on a lot, and I really don’t want to disturb anyone with all the Japanese gibberish (to them) leaking out.
    I sometimes listen to electronic-dance-music too, so how good is this with that type of song? Since I saw below you mentioned AIAIAI TMA-1 is better, but that one is out of my budget.

    Thanks in advance.

    Hey Mike, I am recently looking to buy a portable/semi portable headphone for daily commute. Is there any out there that you recommended? I checked out SJ55 and Marshall Major. Sj55 seems like an interesting choice, but where should I buy it from besides ebay?

    At the same time, I use the Ultimate Ears TF10 (IEM) everyday during commute. I am hoping to buy a pair headphone that sound better than that(or I am just looking for a different sound). I don’t really like the sharp treble on the TF10, since I listen to a lot of Cantonese music (jazz,blue,pop). 

    Can you please give me a few recommendations please?

    I have the HD668b, that is why I am putting my comment on here. This pair is really awesome for its price. <– You article got me pulled the trigger

      The 668B would be better paired with a CmoyBB as it would add warmth and mid body for music listening. Actually I’d recommend the HD660 or the HD661 now for music listening, better than the HD668B.

    Hello. I have been suggested these headphones in a forum. I like several kinds of music, from classical to rock and metal. I like a lot the sound of the bass (the instrument, the bass guitar) and I would like some headphones that allow me to follow that instrument in a song. Take for example this three songs:
    http://www.youtube.com/watch?v=NCpSKrpAdOs and
    http://www.youtube.com/watch?v=CS5sNPTPL6g and http://www.youtube.com/watch?v=wZuoMR-rXOg (i know they’re just youtube videos, but I do have the original CDs, so a good source is granted). Although kind of simple, I love the bass lines in them, so I would like some headphones that let me keep track of them. Do you think these headphones should do the trick? Thanks in advance for your time and your answers. Cheers!

      I listened to the first track, I think the HD668 would give enough separation for the bass tracks there.

    I have to give you a hand for writing this informative review and, in effect, encouraging me to make the plunge to buy these headphones–I simply cannot get these off my head! For those who may have their doubts, I assure you these strike a perfect chord between neutrality and fun factor, and are cheap to boot.  These made me not give up on the hobby of audiophilia, dethroning my 3 year-old ATH-m50s and canning old Saint Nick’s plans of giving me a Beyerdynamic DT 880. As a longtime headphone user, I have the listened extensively to the Teutonic triple, the Grado line sans the PS1000 and almost every headphone in between. The Superlux HD668b are by far the most entertaining of any of them, diving deep into the mix while keeping it juicy and interesting at the same time and are certainly the best value for the money for cans. Mike, thank you again for ultimately having a hand in me making this purchase!

      The full size Superluxes are more or less equally great for classical. I like the closed back better as they have a more powerful bass impact but you’ll have to bear with the closed housing reverb. The HD668B doesn’t have the housing reverb problem but the bass is more flat.
      I need bass for symphonies and pianos.

    Would this be better than the AKG K240 Mk.II? I’ve finally narrowed my choices down to these two (HD668B & AKG K240 Mk.II) but I’m not sure which one to pick. The 668 is basically have the price of the K240 but the K240 comes with a velour pad/extra cables… so I guess I’m really just paying for the accessories.

      So which of the 2 amps has the best bass boost for the 668? I don’t think the simple one or two-position bass boost controls have enough flexibility to be satisfactory for a wide range of music. The FiiO E07k has a digital boost that goes 1 to 10, which is more flexible, unless you need one of the other two amps for some reason.

        Yeah I really love their design and also my budget is small.
