I had a look at some of the others. But I only tried the Bose. My only real concern with the types that didn't cover the ear a la DC's as Clarrie pointed out is when you DON'T have the anc working, ie, flat battery. Pretty noisy!!! The Bose was better in that respect, although certainly not in the DC 13.4 class. (that's what I used to use). I haven't had a problem with prop synch so far. I can hear radios on speaker ok, so I don't anticipate any problems in that respect either. Best investment for my hearing I've made I think.
