My crap Turtle Beach PX21s went out and I am looking to get a new headset. The U 320s from Sennheiser look pretty good and work on pc and ps3 which is what I need. But are they worth the cost? Do they actually last? How's the sound quality? I don't mind the $130 price tag as long as they actually have decent build quality and last. Are there any other good quality headsets out there that work on pc and ps3 you would recommend? I'm never buying Turtle Beach again so don't recommend those please.
