I'm in need of a new headset, but I've never actually bought one before so I'm a bit in the dark. A friend loaned me his Logitech G930, and while the audio quality was good and it was fairly comfortable, I didn't like how much it muffled outside noise. Specifically, while wearing it my own voice sounded very muffled and that was frustrating to me.
So, basic criteria:
Good audio quality
Wireless(preferably with usb recharge)
Comfort
Doesn't make my own voice sound muffled
