This headset really kicks. There are 2 40mm speakers in each ear and the rear one sits in a bandpass enclosure designed for deep, thumping bass. If you like dubstep, these headphones are for you. I've loved them so much I carry them around with me and use them with my Galaxy Player and now my CMoy amp. They have pristene sound with clear highs and mids and insane bass. I have recommended this to over 4 friends who immediately bought a pair after listening to mine.
Now to be honest about its downfalls.
If you use it straight on a mobile device (not designed for this so maybe shouldnt be a "downfall") and you equalize it to give it that extra punch it will sometimes attenuate highs a bit. This isn't an issue in and of itself because you can still hear them very well. The only issue here is when the bass dies down sometimes the highs and mids will "pop" out and scare the crap out of you. I emphasize /sometimes/ this is by no means a common occurrence.
Overall I highly recommend this for any audio application and for gaming/movie watching.
