Query: Peltor H10A

I have only used a few earmuffs but by far this is the best one that I have ever used. These earmuffs are easily 2-3 times as quiet as my other no name cheap earmuffs that I had, and I paid almost as much for those as these. When I put them on, I almost can't hear anything. Nice tight fit around the ears and the head size adjustment stays in place.
