I shoot between 13,000-15,000 shotshells annually in sporting clays with a ported gun and now really getting into the big rifles with muzzle brakes
. I have tried and own the following:
PRO-EARS Electronic LE's: fantastic for clays as they allow you to hear a trap release and do a pretty good job of dampening. Their customer support on one warranty issue was great. They are not suitable in my opinion for rifle work. They offer 50db of adjustable gain for wearing while hunting or at the range and claim to dampen anything above 70db. I just don't find them to be able to dampen more than about 20db (my guestimate) when exposed to a really loud rifle.
Peltor Ultimate 10: What a value!!! I paid a whopping $19.00 for these and they are the most comfortable headphones I have ever used. They offer 30db of noise reduction and that is something you really notice with the big rifles. Highly recommend. These things are big but somehow they do not seem to interfere with the comb.
I have used similar smaller ones from Dillon and Silencio and they do not even come CLOSE!! I'm ordering another pair for my wood shop and giving the others away.
Custom Molded Plugs: Great for use in the hot summers (this is TX). Great noise dampening when really put in properly. Downside is having to clean them after every use and over a period of 2-3 yrs they harden. Still not quite enough for big rifles but great for clays.
