Agree with the Bose lovers, much better than the HMEC which I was really glad to get rid of on E bay. It is more comfortable, seems to be better at noise reduction by I would guess 20% or so (percieved) and batteries are lasting me 50 hours or so which again is about 20 to 30% better. But my only complaint is that the sidetone of your voice as you TX is very low. Does anyone know how to boost it pls?
