My buddy had done some favors for me while I was deployed to Afghanistan, and I bought him a pair of Peltor 6S's for his efforts. We went out hog hunting the other night and had to spend a lot of time just trying to get the batteries installed. It comes dangerously close to tearing up the unit just to open it for batteries. STRIKE ONE. When we turned them on, all you could hear was a faint static sound, compared to the Howard Leights I was wearing they were miserable. With my Howard Leights I could hear quite clearly the animals, insects, and our foot steps as we walked. STRIKE TWO. Lastly, the knobs came off several times just handling the things. STRIKE THREE - YOU'RE OUT!!!! They are on the way back, and a pair of Howard Leights are on the way to my buddy. BOTTOM LINE the Peltor 6S are JUNK.
