I have a turtle beach x1, it cost me $50ish. When you plug in a play n' charge it makes a electromagnetic sounds that drives me crazy.
Basically, if a guy comes behind you or is somewhere near you, you will most likely hear them and know the general location; if your concentrating.
If i may recommend, you should get a tritton headset. Better speakers, doesn't make that electromagnetic sound, and it compatible with xbox, playstation, wii, and computers. Trittons are the same as turtle beaches price range. The better the headset, the more it will cost. Go on buy.com. You can save some $$, plus sometimes you have free shipping.
Hope this helps.
