I use the Tritton 720+ for BO2 with my 360, and it works great.http://www.trittonaudio.com/prod/720plus.asp
It's a little above your price range, but well worth the extra cost. Solidly built, and good consistent sound quailty, plus separately adjustable volume for voice and game audio. You can also hear your own voice through the headset so you aren't yelling at people unintentionally. It is corded, but the cord is easily long enough to reach across most rooms.
