This headset for Xbox 360 is simply the best level quality / price. It offers good sound and dynamic bass thanks to tuning the dial on the cable is simply huge (even the Sennheiser 200 I bought 2 years ago did not offer the ....). It is also very comfortable (even after 8 hours of game Gears of war I did not even warm ears !!) Regarding the installation I was forced to go for a ride on the net, see some videos as no installation manual is supplied with the headset. In short, do not hesitate, go for it, it is cheap and is really surprising!
PS: For HDMI users like me do not forget to buy the Optical / RCA Adapter for Xbox 360.
