Hey all, as topic, does anyone here use one over the standard wired one? I was thinking of getting one, just for the wireless convenience and not almost dipping the headset in my drink every time I take a sip! 
How long is the battery life usually? Is it mains or USB charged? Good sound quality?
Thanks!

Charge time is 4 hours with a usage time of 8 hours. The long charge time isnt really an issue for me since I top it up everyday for an hour so its always at full charge.
