Maybe i've been to 100 or more concerts but wore earplugs every time, i've seen plenty of amazing bands live but from the first concert i went to in the late 90's, most of the time i thought was it was painfully loud ... the mix was horrible, couldn't hear a damn thing... the earplugs rendered the shows OK but never like WOW this is crystal clear sound (ok maybe the gossip sounded pretty good
)
But i'm quite bitter that maybe 90% never wear earplugs and still don't get tinnitus, that's quite puzzling. Usually it's people who make fun at you when you have earplugs who don't have it lol !
If AM101 works, i don't think i'll be going too much to concerts anymore, they are always too loud and i don't see that changing... in switzerland though it's 93db max, that's quite good imo
