Hi. I hope that this group is appropriate for this question.

I was recently at a rock concert and was lucky enough to find a spot
near the stage. The show was great, but too loud. I had a pair of
cheap earplugs that the health department gives out, so I slipped them
in. The music then sounded awful. I noticed the guys in the band used
ear plugs also, but I assume that their plugs didn't diminish sound
quality as much.

Does anyone have any recommendations for a good brand of ear plugs that
will allow me to enjoy the music while not damaging my hearing?

Thanks.
