I bought these for riding as my helmet is quite noisy. They block significantly less noise at any level than foam plugs but are a little more comfortable. They have put a stop to the ringing in my ears after long rides too! However, I took these to the indoor range a few weeks ago. Put them in, gave them a good poke to be sure (stoppers inserted) and stepped into the range. After about 3 shots (from other people, I hadn't even gotten my gun out!) I had to leave the range to put on better hearing protection as my right ear was already starting to ring. I'll give these another try but for now, they are only being used as a sound dampener under my helmet.
Pros: mid-level sound dampening
Cons: not quiet enough for shooting!
