Only got this yesterday, but have probably used it for about 8 hours or so. Seems really easy to use. Just plug everything together, make sure it's charged (they recommend charging it for 2 hours before using it when you first get it), pair your headphones (I have Bose QuietComfort and they paired easily. My old Jabra wouldn't pair at all) and away you go. I thought all sound would come through the transmitter, but it doesn't, so I had to turn the volume down on my TV, but now that I know, it's not an issue. Doesn't seem to be a delay between my headphones and what's happening on the TV, but there normally isn't with my headphones, so that's good. Haven't used it in the receive mode, so I can't judge that, but I didn't get it for that.
