I have a set of Pro-Ears (2 sets, really...got some for my wife, but she has too much tremor [tardive dyskinesia, for you medicine fans] and can't shoot fer beans anymore, now my daughter uses 'em). I like 'em a lot, but they have two major faults:
1) I can't wear a hat; in winter this is not fun. Worn behind the neck
or under the chin, they don't fit, and the ear cup is too big
anyway...still can't wear a hat.
2) In the summer, they make my ears sweat; I'm a slimy mess. (no
smart remarks!)
BUT...they work really well; I can hear the guys talking on the next range (about 100 yd. away) like they were next to me, but I don't have any problem from muzzle blast. Only time I had trouble was when a guy shot off his FA .454 Mag about 3½' from me last fall...didn't really hear it, but it made my ears ring. So I got behind him and used HIS dumb head (he's one of those guys who thinks that if he can't hit with one gun, what he needs is a bigger one) to block the shockwave.
