Simply put, the best PC gaming headset I've owned.
Super comfortable,really great solid build with all metal internals, a quailty mic that is detachable, this is a big plus if you just want to chill out an listen without a mic annoying you. The big 50 mm drivers are excellent and the sound quality is on par with much more expensive audiophile ones, I haven't found any distortion even at max volume, though this of course means to get the very best from them you need a good sound card with good amp to power the beasts.
And of course the price.. For what you get.. I cant think of any other headset on market that comes close.
