you got two ears, you only need 2 speakers in a headset. unless ur in a theatre room, 7.1 surround will never help you at all. Also, I find that their "mixamp" is a gimmick, personally, I would rather get a xonar essence stx and just some ballin headphones and call it a day. My brother used these for a while, says they are nothing special even with the mix amp. Take ur $249.99 and invest into a real headset and a sound card.
