I've had Turtle Beach X12s for more than two years, and I'm thinking of upgrading. Not just any upgrade, though. I'm willing to spend $400. I've looked at some online, but I'm still not sure what to get. My criteria: it should not have an overly sensitive mic, and block out other noise (my X12s could capture sound from across the house sometimes); Surround sound is something I expect at that price, and have heard simulated is better; wireless is a plus, but not necessary, as I will mainly use it on PC; Xbox 360 compatibility would also be nice, but I can always use my X12s; any other nice features would be great. If its a little over budget, I might still consider it.
