I received my pair today and have to say I'm impressed. I've been wanting a wireless gaming headset and when these were announced last year I knew I would be buying them.
The only issue I'm having so far is that I have no idea how to turn them off. According to the manual I'm supposed to press the logo button on the headset, but that only results in a single beep without powering down. They also don't seem to automatically power down after 10 minutes of no audio. I have the transmitter attached to my PC with USB and an optical cable.
