I have the Turtle Beach px22, its doing pretty well, though i have a bad tendency of messing around and blasting my music, which has taken a small toll on the bass in the headset, but its only minor. other than that, the actual headset itself is still in good shape and the mic quality is great.

Heard the px21s are more prone to breaking than the px22.
Also, don't get Steelseries Siberia V2, Got mine a while back and the mic broke rather fast. They are kinda nice looking, and they sound pretty good, but if you are looking for a dependable mic, stay away.
