right now i have turtle beach 5.1 headset. I bought it from newegg about 8 months ago for 89.99
The sound quality is amazing, the mic went out about 3 months but i just hooked up a new one and its perfect. I think i am going to get the medusa USB 5.1 headset.
Their headset was rumored to be banned from CPL (pro counter strike league) because it was so good. I dont believe this to be true, but all I have read is that they are amazing headphones. The USB 5.1 are 125.00 USD
