Howard Leight Impact Sport electronic ear muffs. Being able to hear normal speaking volume and yet still protect hearing from the shots is awesome.

Around christmas time last year they were about $35 or so from amazon and cabellas. At that price, they were a great deal. At $50, there are probably some other electronic muffs I'd check out, but I'd still go for some electronics.
