1a - Clean Sound - Very nice thing.

Sooooooooooo.
On the one hand is the headset really worth the money, rarely had such a nice headset like this.
To gamble it really 1a. Games tested: WoW (Arena), CSS, Cs 1.6, BF3, MW3 - As reported by others, you feel like you caught the game.
Also watch movies makes irsinnig fun with 7.1, also here you think you should be part of the action.

and now what I actually use. Listen to music.

The 7.1 feeling extremely bass-heavy music is amazing - I can hear most of the time & Dubstep I think partly that my headset is alive - it is vibrating so hard on and the highs and lows are just as fascinating. Haleluja.

Really, who wants decent listen to music - it buys you - I'd buy me any time.

Nice but useless feature is the voice changer, which is in the software here. From time to time in the TS funny, but useless: p

Software support 1a. The 3 programmable keys on the side of too super to eg ingame just stop NEN song, or NEN song skipping on.

~ It could also be ne subjective opinion, but in the beginning was the headset I think loud, not that it now would not be loud, but somehow it was sometimes louder ~

CONCLUSION: very very GREAT BUY recommendation!
