I paid $30 for a pair of Caldwell E-Max Low Profile NRR 23. They're okay but depending on who's shooting what at the range, I still wince on occasion.

I could put ear plugs underneath but then I can't hear conversation. Kind of defeats the purpose, don't it.

What is the highest NRR available in E Muffs? How much should I expect to pay? I'm willing to put out the dinero if it's justified.

Please to share the good, the bad, and the ugly. Thanks.
