Superlux HD668B Headphones

There are better headphones out there, but you absolutely cannot get better headphones than these for the price so I'm quite comfortable giving it the full 5/5 rating and full recommendation. These are semi-open(as opposed to closed or fully open), but the distinction between these and fully open headphones is negligible, quite honestly. Definitely consider these open headphones, just with a bit less sound leakage. And despite that lessened sound leakage, these are not short on sound stage whatsoever. Superb for gaming especially. Sound quality is also surprisingly good. Being open-backed, they will never be for bassheads or even close, but they do still have sizeable 50mm drivers that deliver satisfying and balanced low frequency response that is better than many other others in the open-backed space. The mid range is strong and clear. The one weakness is the higher highs that can be a tad harsh. EQ can sort this out quite well, but not everybody is in a position to use an EQ, so it's still worth mentioning. But that really is the only 'knock' I can give to these in terms of sound. Sound quality overall is very respectable and you wont find better without venturing into the £100+ category, and even then there are honestly some I'd put these above. At 56ohms, they're not super hard to drive, but a bit of extra amplification does help. The construction and feel of them is pretty cheap. You can tell this is how they've managed to offer such good sound for so little a price. Nevertheless, I found them very comfortable. They are light and dont have any tight clamping force that puts pressure on my head/ears. I can wear these for long periods of time, no problem. You can also fairly easily replace the earpads with velour ones for even better comfort for another £10-15 or so, which is worth doing if you plan on using these as primary headphones for a good while.

First of all, these are great headphones for a budget, or if you want to find out the hype behind "audiophile" equipment like I did then this is a good gateway. These headphones by no means are real audiophile equipment, or particularly amazing at anything. They have a V-shaped sound signature which means they excel at music with highs in, but music which keeps in the mids is really not that great. They have a good amount of bass for open back headphones and at the volume I usually listen at they do not leak too much, though these are not headphones you should be wearing outside really. Overall I would say the sound is quite good after burning them in, when you consider the price, they are cheap but hit above their price really, just if you really want some good headphones be prepared to spend much more. Their build quality, to say the least, is bad. While I have no gripes with the nearly all plastic build, as they have not broken after almost a year of use, they are mostly plastic and their feel is just cheap. A lot of people replace the earpads that come too because the pleather material is not very good but I have not had as much issue with sweating or clammyness so it just depends on the person. They clamp quite hard depending on your head size but I have not had issue since day 1 using these, though the head rest 'wings' still are not exactly the most comfortable things in the world and I would recommend that you bend them back. They have a removeable cable which is a big plus if you are worried about a pet chewing through them, I didn't really factor this when buying them as I won't break it with abuse from bringing them out (I only use IEM's outside, and wouldn't wear these in public) but it's nice that you can do this as even on very high end equipment you don't always find it. I use these mainly for just listening to stuff on my computer which mainly centers around gaming, music and videos. They work fine for this and are good enough for that, because they're open back sound positioning in games is very good so I can recommend them for that, they work much better than most much more expensive "Gaming" headphones when paired with an external microphone. (Note: I never ran these through a proper DAC or AMP, I do not know how well these benefit from them but I doubt too much difference) In conclusion, I can definitely recommend these headphones, they have a nice V shaped sound which meets my music preferences and don't lose too much detail. In gaming they are ideal when paired with a cheap microphone as a budget solution versus a gaming headset. Get these if you want a decent sounding pair of cans with plenty of mods available, if you aren't on a budget look elsewhere at other real audiophile grade gear, you won't regret it when you hear the difference.

My last pair of bluetooth headphones (Edifier W820 NB) broke and wanted to try wired headphones again. If you are absolutely sick of wasting money on expensive Bluetooth nonsense with batteries built to die, definitely consider these. The clamping force is decent - comfortable, but won't fall of your head. The pass-through and soundbleed are fine - not recommended for wearing around loud traffic, but fine in busy streets. Plasticky and cheap feeling, but feel quite robust, wouldn't use them as a weapon though. But that's all window dressing, the real review is in the sound - it's good! Fine enough for the price, that reputation is well earned. However, you can make them even better with a custom sound profile on your device of choice. See the picture on this review, bump up the sub-bass / bass a bit, lower the high tones a touch and you'll find yourself with sound that's on par with some £100-200 headphones (I almost cant hear the difference between these and HD600s)! Do yourself a favour though, get replacement ear pads - the pads that come with the headphones are stiff, rubbery, squeaky and generally crap. If you value soundstageing get bigger pads than come with the headphones. Consider getting a headband pad too, since the headband can and will 'boing' when walking, which is loud and annoying. The packed in aux cables are nice and highly appreciated too - loud as hell, though. Top job, Superlux. Very impressive for the price.

Vale, lo pille y se escucha todo de buena calidad, trae 2 conectores y lo hace multiuso para tocar la guitarra y más, tiene una calidad ALTISIMA de sonido, claramente tienes que amplificar los bajos un poco pero la verdad se escucha mejor Tenia un problema con mis antiguos cascos, no se escuchaba nada los bajos y en canciones con muchas cosas y melodias se escuchaba confuso, los superlux solucionaron todo esto Eso si. lo único bueno/malo es que agarra mucho, y duele un poco llevarlo por mucho tiempo hasta que te acostumbras, pero eso es porque se sujeta muy bien en las orejas

この価格でこの音質は最高でした。 オーディオだけでなくギターやベースのアンプでも素直な音でお高い某メーカーの物より個人的には気に入っています。 何というか音が素直なんですよね。かけ心地も良いし。 値段や神話にとらわれない方にお勧めです。 私は２万円のヘッドホンをメルカリで売ってもう一台買いました。

didn’t work properly, sounded horrible and i had to pay €15 to return it as well. horrible.

The good thing is it makes you listen the hats clearly but the bass not that good

Se il suono delle Superlux HD-668B, nuove, ti lascia a bocca aperta, aspetta di sentirle dopo un paio di mesi di rodaggio. È qui che accade il vero miracolo: i driver sembrano sciogliersi, guadagnando in fluidità, respiro e naturalezza. Quella precisione chirurgica iniziale non perde un colpo, ma si arricchisce di una consistenza e di un'autorevolezza che solo le ore di ascolto possono donare. È come se tirassero fuori i muscoli, rivelando tutta la potenza e il carattere nascosti. Il vero salto di qualità, però, lo fanno quando vengono alimentate e gestite da una scheda audio seria. Collegarle a una Focusrite Scarlett 2i2 di quarta generazione è come sbloccare un livello superiore. La scarlett fornisce l'energia pulita e il controllo totale di cui queste cuffie avide hanno bisogno: il basso si fa ancora più definito e profondo, la già ampia scena sonora si espande in larghezza e profondità, e ogni dettaglio emerge da un fondo nero di un silenzio impeccabile. L'accoppiata diventa un sistema di monitoraggio a bassissimo costo di una precisione disarmante, perfetto per produzione, missaggio o ascolto critico. In definitiva, le HD-668B non sono un affare: sono un investimento sonoro. Da sole sono straordinarie; dopo il rodaggio e abbinate a una interfaccia dedicata come la Scarlett, diventano uno strumento professionale, rivelando dettagli e dinamiche che umiliano cuffie di fascia molto, molto superiore. Un caso di scuola.
