Xbox 360/PC Sharkoon X-Tatic SX Stereo Gaming Headset $49.99 (Reg. $59.99)

I'd say a pretty unknown brand for a headset, but it has amazing reviews on Amazon. Also, it's pretty cheap. Some of you might want to check it out, I know I will, eventually.

Forgot, it also doubles as a PC gaming headset.
