I'll go first.
Earplugs, b/c all the muffs I've tried hurt my ears, don't seem to block sound as well, and I can't figure out what to so with them between clips or if we all have stopped to reload and are talking. I tried just letting them hang around my neck when not in use but they are too bulky. Granted I 've never used a real expensive pair, just what ever you can pick up at Wally World. When I say ear plugs I'm not talking about the squish and expand kind, I'm refering to the soft rubber non-desposable kind. Which my prefrence my have something to do with having to wear earplugs in a factory for about three years, I could be just use to them.
