Hearing that is.
I found this [ame]http://www.youtube.com/watch?v=6w5hclSlRsY[/ame]I use a pair of mold-your-own ear plugs that I bought from MidwayUSA. I've found that I can hear conversation and range commands better with them than I can with ear muffs, they seem (IMHO) to block impulse noise better than my muffs do, they don't get in the way when I'm trying to shoot a rifle, and they're bright orange so the range officers can see I've got protection in. The best part is they only cost me $12. Been using them for about a year and a half now.
