It might be hard to find wireless and cheap depending on your definition for cheap
Here is the headset I have though.
http://www.amazon.com/dp/B003VANOFY/ref ... wo=&hvqmt=I'm assuming you already know this since you're looking for a USB headset but USB headsets install their own audio driver. This means if you have speakers, you'll have to switch the playback between your speakers and your headphones anytime you want to listen to one or the other. The headset has great 7.1 surround sound however I feel like the audio driver it installs misses some things. I'm not sure if it is the games or what but I had some weird audio issues in BF2 where sound would just cut out and I have that occasionally in Tera also. It could be the games, but I have a hunch that it is the audio driver but I can't say for sure. I love having a wireless headset but because of these audio issues I'm having I'm thinking I'll try to find a wireless headset with a stereo jack for my next one if they exist.
