I'm gonna buy a headset tomorrow, and I'm not sure If I want this one.

It's an alright headset from what I've seen, and based on what I've seen on YouTube its a pretty damn good headset.
$60 is pretty much my limit, because 100 dollars for a headset.. (Yao ming face)
The only difference between the x31 and the x11 or x12 is the wireless, the sound quality and everything else is the same.
Amazon has the x12 for 36 bucks. It's the same headset, just with a wire. So unless you absolutely need to go wireless, why not save yourself some money?
