I have flown with two guys who use the clarity aloft headsets, and they both swore by them. The foam tips have to be replaced after a while, but the sound reduction is very good. I heard that the only real difference between the pro and regular models is that the pro is TSOd. I tried on the headsets myself - they are lightweight and comfortable, although the band that goes around the back of the head is not adjustable, but it is lightweight, so it does not really matter.
