I have some Turtle Beach x11 which will work for PC and 360. They need USB power to run and I'd highly recommend using a phone charger instead of a PC USB port as PC ports are quite noisy (electronically).
They sound pretty good, have adjustable game, chat and bass levels, are quite comfy and feel OK in terms of build quality. Only thing I need to do now is work out the sweet spot for the Mic so it's loud but doesn't clip.
