I have used the dillon electronic muffs for years. I have a degree of nerve damage from years of not wearing protection.The main issue is in weather above 60 degrees the sweat becomes an issue for me. They do greatly enhance the little sounds that you forget are there, like light footsteps coming through the leaves that I would never hear.One caution here,snake country. They alter the sound of a rattlesnake. I found out the hard way.I was sitting on a camp stool watching for critters to come to the call, and suddenly dawned on me that there was no running water anywhere around. Yet I had been hearing it for several minutes.I lifted one earmuff and instantly recognized the angry buzzing,close.As I looked down a very mad 4+ foot rattler was backed up against brush, poised to strike,about a foot away from my leg.It had tried to back away but couldn't get any further.It must have been there several minutes by the time I saw it. Why it never hit me I'll never know,I slowly moved the shotgun around and didnt relax till I had him covered.I gave him a few minutes to crawl away but he just kept swaying. I felt that because of the closeness I had no choice but to shoot.Deadcoyote does a number on snakes.I felt bad because he could have hit me and didn't,but then he just didn't listen to reason.Use care!
