I am a professional finish carpenter, concert fanatic, and gun enthusiast. I have several pair of these ear plugs, in my truck, in each of my gun cases, and in my tool bags. I have used many types of ear plugs and none compare to the quality of these. If I had to pick out the best quality of these ear plugs it would have to be the ability to compete with my .357 magnum. When I shoot the gun I can feel the compression hit my face, yet my ears are perfectly fine! Phenomenal product.
