Out of box they sounded very good, FAR better than other similar $ headphones. I would not say "hi-fi" but WAY better sound definition than most headphones under $100. They are not bass-heavy, rattle your noggin cans. They are more in the lane of "reference" or neutral. I thought they had slightly forward highs, occasionally sibilant, perhaps ... but that's a big word and hardly fair for headphones we paid My son bought these to replace some skull candy and originally missed the bass those had. But, over a couple weeks he says the superlux are so much clearer, cleaner, and spacious sounding, he doesn't like the skull candy anymore. He says he can hear all sorts of detail in music he never heard before (and he likes it...). My experience lines up with that from the few tracks I listened to with these (though I don't put his skull candy on my head ... ever). Everyone will be different.... so look up more details elsewhere. But $ for sound, these surprized me in a really good way.Build quality doesn't look exceptional. They don't look fragile, just like they are "just adequate" and not more. My son usually tears things up pretty quick, headphones not withstanding. Hence he paid for these himself ... 2 pairs from dad in My son listens to them with a generic MP3 player and they sound fine, so no amp needed ... but if you add a little juice, they do perk up and shine. But so do most good headphones. I let him listen to these on a class A solid state and then a tube headphone amp, and his jaw dropped. He tried his skull candy on those and went "meh, yeah, better, but ... not like the superlux" The point is, these are surprisingly good headphones for "cricial listening" if it's not blasphemy to say such about a sub $50 headphone, but you get out of them what you put into them. On a marginal source, you may not notice a big difference between these and a typical $40 set but as the source improves, they start to really separate from other similar priced cans.Be aware, if you aren't familiar with semi-open/ open, that means they leak sound - in and out. You can still hear things around you AND others can hear YOUR music even if it's not cranked up. The tradeoff is, again if you are not aware, is that the design makes them sound really spacious. Open/semi-open headphones are rarely this cheap, so in case you wondered into reviews of this Superlux looking for a "cheap but decent" pair of cans to wear on the train while commuting ... hmmm ... think on that a bit.I have a lot of far better headphones ... but for the money, I've not heard anything this "good." It looks like these bounce up and down in price. If these were $70 you could do better for a couple bucks more and would be well to do so (phillips 9500 again). We scored these for less than $40. At that price I'd buy them again any day!! 5 stars for VERY good sound at a CRAZY, CRAZY low price. If $50, I'd say 4 stars because there are other competitors at that price that have better build quality better comfort, and better sound. Hit $75 and I'd drop to 3 stars - too close to Phillips, Sennheisser, and Audiotechnica options that edge these out.

First impressions:This product is amazing... for the price. I was until recently using a set os USB 7.1 Surround Sound headphones from R***r, and I was getting some bad electrical contact and signal from them. Then I upgraded to these bad boys, and they are amazing.Pros:I'd say that they're bass is clean and powerful, but not punchy. They sound they product is more natural; it doesn't feel like listening to headphones, but it feels more open, like I'm listening to a conversation when I'm watching a YouTube video online.Progressive Metal, female vocals, electrical guitars all sound amazing, and explosions also are incredible with these. They're a bit high on the treble, but you can fix that on the equalizer in music or on your soundcard settings (I'm using onboard on my motherboard, and they still sound amazing).I don't mind the fact that they don't include a microphone, since included microphones tend to be terrible anyways.Cons:The clamping force is a bit high, and the pads tend to be a bit stiff. Maybe they'll soften over time, but they're a bit hard for me out of the box.The headband tends to be a bit noticeable, since I have a larger head. You have to bend the headphones back a bit until you can barely feel the headphones on your head, and that's when it'll be most comfortable. Everyone has a spot for that, and it takes some getting used to. I would like some replaceable pads, though.It doesn't eliminate all sound from the outside, though, so if you're in a noisy environment, that may be a con. But for me, I need to listen to what others say while I'm gaming, since it may be important. And that for me is a plus, besides the way they sound because they're semi-open. But it may be a con for some.Included cable is not detachable.Conclusion:Overall, here it is: I really, really like them. They are awesome for the money, and overall. Before you go out and buy some other 300$ headphones, try these out. They're probably more than what you'd expect to get at this price-point, but they'll really surprise you. And buying this might be all you need to get the effect you want, and between spending 300$ and suffering from buyer's remorse or spending 30$ now and possibly avoiding that later, this is a good way to dip your toes into a better audio experience even with an onboard audio solution on your phone, music player, tablet or computer. (It won't need an amp, but it'd definitely help to get higher volume!)I think my recommendation is, if you want some headphones that work well in a variety of music types, and you want crystal clear vocals (especially female vocals) and don't mind a bit or higher treble, but don't want excessively punchy bass, these are the headphones for you. =) I do regret I didn't get the HD 668B's, though, but I still think I made an amazing deal buying these for around 30$.

They sound decent especially for the price. Ive noticed a lot of people saying that the earcups are way too shallow and firm. I have to disagree as they fit my head very well and they dont become too uncomfortable after wearing them for hours at a time. The extra long cable is nice too as I no longer have to worry about accidently ripping it out on my pc. As for the sound, they dont sound bad overall. Im most impressed with its very neutral and direct sounding profile. The bass sounds absolutely incredible, super crisp and clear. The treble on the other hand, is on the louder side than what im used to and sounds a bit harsh. But, EQing the the 5-20kHz range down a bit makes it sound perfect.

Qualidade do fone e duração muito boa.

Compré este producto basándome en las referencias de otros compradores por equipo semejante, que comentaban que estos audífonos valen su peso en oro, y que son buenísimos comparativamente hablando, y que son mejores que otros equipos de marcas más conocidas y precios más altos. Hasta el momento, coincido en que el sonido es genial (realmente no soy audiófilo como para que mi opinión sea tomada demasiado en serio). Dicho eso, mi única queja es que por diseño son un poco inconvenientes para los que usamos lentes, y por diseño de auricular que cubre todo el oído, es un sufrimiento usarlos a menos que enciendas el AC a todo lo que da (cosa que ocurriría con cualquier otro tipo de audífonos del mismo diseño, así que realmente no es una queja, sino más bien una observación si estás comprando y tienes el mismo problema de la climatización que yo). Eso sí, estoy escuchando cosas que jamás había escuchado antes en mi celular y PC.

Très bon casque ouvert. Très bon son pour ce prix défiant toute concurrence !

Nothing can beat the audio quality of these headphones at this price

I bought the headphones to connect them to my guitar amplifier not to disturb my neighbours while I’m playing. I’m more then satisfied: headphones gives me a wide frequency range, clear sound in general, and they are so not harm my years or head in general. Highly recommended
