Works well - Caldwell E-Max Shadow PRO Earplugs

I shoot at an outdoor range that is under cover. I can clearly hear the other guns going off (its loud but similar to ear muff) but what is interesting is that while I am having a conversation, I can't hear the other person talk during a gun shot. They are muted which means the E-MAX are cutting out the sound. These do what they should do. I bought them because my ear muff did not allow me to cheek up to my gun.
