It's official: I'm getting old. I haven't been to a lot of shows lately, but the few that I've been to have been quite loud. I'll be seeing KMFDM (who are notorious for ear-bleeding volumes in Atlanta) in October and I'll catch several Tool shows this fall. I have hearing loss from when I was a kid and I've finally gotten to the point where most rock shows are just too loud, so I'm finally investing in a pair of good earplugs. I'd like something with 20-25dB of relatively flat attenuation for less than $50. I know I can go with cheap foam, but I'd rather not. I'm currently eyeing the ER-20s ($15 in most places). Anyone use earplugs? Have any suggestions?
