Superlux HD668B Professional Studio Standard Headphones

Pros:

First Impressions: The last two Superlux’s I’ve heard were both startlingly good for the money, thus I’ve got high hopes for this one. I am worried thot I may be expecting too much and that if its isn’t as crazy good for the money I may be slightly disappointed. So the box, hmm it’s different but still as weirdly neatly put together inside. After grappling them out of the packaging it’s still a pretty good bundle. Two cables is nice, adapter and baggy thing too. No extra pads this time however. Hmm, the headrest thingys aren’t quite even. That probably won’t matter but visually I don’t love that, a little application of might bend it but err, yeah I don’t feel all that comfortable doing that. These are in the hand clearly plasticy and a cheap product. Mind you the last Superlux’s were the same. Hmm. On the ears.

Oh, goodness, these are pretty damn good. Great control in the bass, super nice clarity to them. Hmm that treble might be a little over abundant for me. In acoustic tracks these are really damn bloody good. Mids a touch breathy but seriously excellent for the price. Why are Superlux getting these drivers from? Hmm there is a fair amount of clamping going on here. These are super interesting. Burn in time.

Bass: The bass is quite talented, really very talented and tuneful. It can even rise up when called to give a reasonably bassy presentation. “Your Father And I” rips into a decent bass line, good and hearty bass too. Now it should maybe be a touch more but it’s a good solid bass presentation. The bass quantity is really more about the relative abundance of treble in the track. From what I’ve seen others comment on is that it’s relatively bass light and on the whole I’d disagree with that assessment. There isn’t a lack of bass. There is the exactly right amount called for in the song. Okay so it maybe can’t cling on all the way down to the very bottom but you can’t forget that this is a 20 quid, delivered, headphone. Seriously how the F are they managing that? For the price it’s amazingly cleanly delivered bass. Perhaps it’s too clean for those paying this price, cheap things normally have far more bloom and flab to them which serves to make the bass sound fuller, larger and these don’t. These are clean and nimble all the way and in a way that you really just don’t expect form an el cheapo. I really can see why they are labelled “Professional Studio Standard Headphones” even if they are too much in the uppers for that really.

In terms of raw quantity, these can produce a bit but that’s so long as there isn’t lots of treble. At this level of cuttingly clean the treble is what stands forth.

Mids: Wow they are really impressive.


Highs: The quality, yeah it’s superb, really stupidly impressive. The detail it wants to spit out is wonderful. It’s very forthright and explicit a presentation.

Comfort: They do clamp rathe

Cons:

after a while the product started to give a sound to the wings, but I think it is luck hope I can get the new. The product is very nice.

Pros:

Наушники сделаны качественно и их хороших материалов.
Посторонних запахов не имеют.
Насчёт звука хочется сказать отдельно:
Я только сегодня получил эти наушники и соответственно они не прогреты,
но звук меня просто поразил. Глубина и ширина сцены удивительны.
Звучание инструментов и вокала естественное, безо всякой прилизанности
и приукрашенности (я не являюсь любителем эквалайзеров и всяких "улучшалок",
но все таки иногда приходится использовать).
По своему форм-фактору, наушники являются полуоткрытыми и я ожидал от них
"совместного прослушивания с окружающими".
Но на удивление оказалось, что звук поступающий наружу, очень не значителен.
Earphones are made qualitatively and of good stuff.
Have no foreign smells.
About a sound there is a wish to tell separately:
I received these earphones only today and respectively they are not heated-up,
but the sound just struck me. Depth and width of a scene are surprising.
Sounding of tools and vocal natural, without adding of colors (I am not a fan of equalizers).
On the shape factor, earphones are semi-open and I expected from them
"joint listening with people around".
But surprisingly it turned out that the sound arriving outside, very much is not considerable.

Cons:

Наушники с вентиляцией не дружат и для меня немного жестковаты амбушюры.
Earphones are not on friendly terms with cooling and for me embouchures are a little hardish.

Pros:

Wow, now this is bang for the buck literally! I have read alot of positive reviews on this product, and i have to add my own, just as positive review to the choir of joy! The design of the headphones is very simple, but its not without function. The light metal structure is adjustable, you can shape it to your liking without effort. The were somewgat tight for me to begin with, so i adjusted the pads that rests on the top of the head and now its a perfect fit. I heard people complain about the earpads, that they were uncomfortable and to hard, however i disagree. I think the earpads are just fine, and i think people complaining did a bad job in adjusting the headphones as i described above. Now to the really funny part, the sound quality. I can just describe it as a very balanced, crisp sound where u can listen to all details in the song not having them obscured by bad sound quality. I find myself listening through lots of old songs, who with Superlux HD668B is resurected to a new, better version of their old selves. If i knew how good these are, i would pay alot more, at least 150 Euros and still felt like i made a bargain. I recomend these head phones without a doubt, especially if you are on a budget, i think you have to pay quite a bit more go get the same or better quality. Epic!

Cons:

I find myself listening to old songs to much, they sound so much better, its time consuming!

Pros:

Bass
Bass is tight and has good amount of weight. It is not meant for bassheads. Does not overpower Mids. Would say it's not a too aggressive nor relaxed signature.

Mids
Vocals are slightly forward sounding. You can say they're pretty detailed and clear, with good depth. Vocals are more towards Sonic character rather than neutral.
Partly due to perceived quality

Treble
Couldn't really perform well at the higher frequencies (mid-upper treble)
Mid-upper Treble is a little harsh/sharp and bright
Airy
Guess they need some burn in

Soundstage
As treble is airy, Soundstage complements
Soundstage is wide here (well, it's open back :D)

Sound separation
Separation of sound is well done here
Tried the free DSD album that came with the mojo


No cable microphonics
Cable is thick and solid

Conclusion
I loved it the most on acoustic songs.
Vocals were very intimate while accompanied with a classical/acoustic guitar

Can't tell whether the B represents Bass as I don't own other open back earphones.
But most likely I would say it is a bass boost as it pretty much satisfies me as a bass lover.

Cons:

As per mentioned above

Pros:

The sound may be a bit bright for some folks but for my older ears these are perfect. If the highs are too pronounced you can always dial them back with an equalizer. Nice and full bottom end but not a thumping bass, just enough to tickle your ears from the vibrations. Mid-range is just as strong as the highs and lows so overall a very balanced sound profile. What surprised me the most is the quality of the sound. I have many pairs of headphones, some that were over $200 U.S. If I knew then what I know now I would just purchase these and saved myself a LOT of money. These are very light and comfortable I did replace the stock pads with some Cosmos velvet pads for the AKG K240 which fit perfectly. These also have a wider sound stage than my other open-back headphones which was surprising to me. Seriously, at this price there's no reason not to get these if you like listening music (I can't speak for rap/hiphop as I don't ever listen to it). For reproducing music, these will beat many (if not most) headphones in the $100 to $200 price range.

Cons:

It did take awhile for these to arrive here on the east coast of the U.S. but they arrived in perfect condition after about three and a half weeks. The construction is solid although overall there's lots of plastic used. I would prefer a female connector for the headphone connector input as opposed to the male plug that is used.

Pros:

Looks very good. Can not say nothing about long term reliabilty - let's see, but for this price I can replace it every year. Good fitting to the head. Soft touch and the pressure can easily be adjusted bending rod springs. But be careful! It's easy to overcorrect.
Sound was checked in comparison to AKG 240 MkII. Having the same impedance they seem to sound a bit louder than Mk II. 668 really gives high definition sound not masking instruments. The whole sound landscape is similar to 240 regarding definition. In comparison to 240 this headphones has more mid-highs and slightly different bass, so they sounds not so truly, emotionally dry and noble but it is not a disadvantage if you plan to use 668 for listening music, It's rather pleasant corrections for most types of music. Anyway, if you have an equalizer it's easy to correct as you prefer.
Great for this price as a monitor headpfones, for overdubbing. etc. Great for everyday listening.

Cons:

None for this price, but it's not for sound engineering work, for sure. :)

Feb 01,2018

Pros:

Suddenly a wide scene. Smooth and pleasant sound, subjective sensations do not have enough details in the middle, but this is absolutely not critical, high detailed, but not perfect, I thought the bass will be smaller, but it is there and it's nice. It is written that they are for information, but I would say that they are more suitable for home listening, comfort in them is more than dry analyticity. Sounds much more comfortable than my old ATH ws70, and they seem to be for non-professional listening. But if you compare it with the ATH AD700, then the HD668B will be a little harder, and, probably, a bit less airy (after all they are half-closed) and they will have fewer details, in general, the sound is not worse, it just has a different shade. In general, all this ridiculous nitpicking, given their cost, the headphones sound softly, they sit comfortably, I hope they will work for a long time.

Cons:

For this money, it is unlikely that something like that can be bought. Made qualitatively, light, strong, hold securely, the arch springs very well. Of the possible disadvantages: can cause discomfort with prolonged use, if the size of the head does not fit (on the big head it will be possible to press, although I do not have a small one, and all the norms, the main thing is to choose the correct landing, even you do not need to adjust). The sound can be adjusted with any equalizer in accordance with your preferences.

May 07,2018

Pros:

Неожиданно широкая сцена. Ровный и приятный звук, по субъективным ощущениям не хватает деталей в середине, но это совершенно не критично, высокие детализированы, но не идеально, думал баса будет меньше, но он есть и он приятный. Написано, что они для сведения, но я бы сказал что они больше подходят для домашнего прослушивания, комфорта в них больше чем сухой аналитичности. Звучат значительно комфортнее моих стареньких ATH ws70, а они вроде как для непрофессионального прослушивания. Но если сравнивать с ATH AD700, то HD668B окажутся чуть пожестче, ну и, наверное, чуть менее воздушными (все-таки они полузакрытые) и деталей у них будет поменьше, в целом звук не хуже, у него просто другой оттенок. Вообще все это нелепые придирки, учитывая их стоимость, наушники звучат мягко, сидят уютно, надеюсь долго проработают.

Cons:

Даже как-то нелепо говорить об этом, образцовое сочетание цены и качества.

Feb 18,2016

Pros:

- Very light, there is little pressure on your head while wearing these headphones.
- 56Ohm drivers provide good quality sound with little noise.
- A very good frequency response curve, from 100Hz to 10kHz the frequency response is almost linear. Although on the treble near the 15kHz range, it can get a little bit overwhelming, depending on what sort of music you listen to.
- Great cable length (total of 4 metres) with 1m cable + 3m cable.
- Includes a quarter inch audio jack to 3.5mm jack adapter.
- Provides amazing soundstage when playing video games especially FPS.
- The two headband cushions provide great head size adjustment and comfort.

Cons:

- Stock "leather" earpads are quite uncomfortable and makes wearing them unpleasant at times. However you can find cheap velour earpad replacements for K270 headphones which have same cup size.
- Non adjustable headband means might not fit everyone.

Dec 18,2017

Pros:

Качество звука, оно действительно на высоте: высоких частот немного много, но они разборчивы и не сливаются в кашу, не режут слух; низких для меня достаточно и они приятные не бубнящие (для любителей мега баса не хватит); детализация звука отличная; сцена хорошая. Это мои впечатления от звука наушников из коробки. После прогрева звучание должно ещё улучшиться.
Доступная цена (брал за 1700 рублей), сложно поискать что-то лучше за такие же деньги
2 отсоединяемых кабеля в комплекте (1 и 3 метра), можно заменить любыми.
Амбушюры хорошо прилегают к голове, вполне мягкие (бывали о жестче).
Комплектация: чехол-сумка, кабели, преходник на 6.3mm, зажим для соединения кабеля с наушниками.

Cons:

Для первого времени посадка на голове жестковата, но можно самому немного отрегулировать и со временем это должно решиться.
