These earmuffs work great. They mute sounds from my buddy's duck call to me snapping my fingers when turned up to full volume. I can actually hear better with these on than without. There is some white noise when you do crank up the amplification all the way so play around with it. They are light and compact, and you barely notice them after a while. As for field experience, I took them out duck hunting and was in a small blind barely big enough for the 3 of us. I put these on and cranked up the volume to full. Everything loud was muted down to a pleasant level, including the shotguns fired in close quarters, and everything quiet was very audible. Great for a first set of electronic muffs, hunting, and shooting in general.
