Actually work pretty well - Rifleman OPMOD Tactical Passive Ear Muffs

Ok for $7 I wasn’t expecting these to work very well, but I was pleasantly surprised. I bought these just because they were on sale and thought what the heck might as well have a couple back up pair. I don’t have an indoor range within 100 miles from me so I can’t say anything about using them indoors, but they work great outdoors. They don’t take all the sound away and aren’t as good as my electronic ones but they are perfectly fine, especially for the price. I saw a few reviews that they are not adjustable but they most definitely are. All you have to do is pull up and the rod that goes into the muff and they will slide up and down.
