I recently picked up a Turtle Beach X11 headset to replace the original headset that game with my 360. I went with the turtle beach over the standard headset because they pump the game audio through the headset as well. This allows me to play late at night without worry for waking the kiddies or wife (not sure which is worse to wake up lol). Set up is pretty straight forward if you are using the standard AV cables or even the component cables. If you are on a 360 slim and running HDMI it is a lot harder to connect the game audio to the headset without buying another adaptor from MS. Luckily my Pioneer AV receiever is close enough to my 360 to allow me to connect the headset to the headphone jack. I totally recommend the X11. They are worth the $50.
+ Game audio through headset
+ Great Sound
+ adjustable size fits even my giant head
- tricky setup with HDMI
- a little heavy
