Does anybody know if there is an affordable (under 100 bucks) electronic ear plug made? The kind that allow conversation noise to pass but block loud noises. I hunt waterfowl a lot and do a lot of shooting. It's taking its toll on my hearing. I want to be able to converse with hunting partners but block out muzzle blast. The only ones I have found range from 500-2000 dollars. I hate muffs and don't need an amazingly great pair just something that Will work semi decent. Any ideas or feedback from products you have tried?
