Interesting thread. Wifey talked me into going to a Moody Blues concert this coming November. I normally avoid concerts because I already have a hearing loss and severe tinnitus. Loud music will only make it worse. I figured I'd have to wear earplugs, which sort of defeats the purpose. But she wants to see them, so we'll go. I regularly wear either the yellow foam cylindrical plugs or tapered foam plugs, but some of these higher grade plugs look like they may offer some protection at the concert and still allow me to hear the fine points of the music.
I also have the problem with hearing conversations of even someone right in front of me if I'm in a room full of people. Has anyone here tried the Bean earplugs (or personal amplifiers)? They're certainly a lot cheaper than dedicated hearing aids, which I don't quite need yet.
