We have Turtle Beach PX21 for the PS3 and PC. Though the Turtle Beach will work with pre-slim Xbox versions. You need an adapter to use them on the current slim models. Tritton Xbox 360 branded headsets is what we use for our 360.
Personally though, I find the Turtle Beach headsets being a pain in the ass to set up, thus I never use them on PC, I just use my Beats.
