I spent years being "that guy" with ear plugs. I used to buy the cheap foam construction-style ones by the box of 200 and would just toss them in coat pockets, cases and glove compartments. It used to be the ritual for awhile that I would forget until the first song and then catch it for the second. Few years ago went and got fitted for pro-quality plugs. Had to go through all the testing before they would do it. I was told that for what I do my hearing is significantly intact; I'm at about average with what a non-musician would experience. Never been more thankful to be "at about average or slightly better."
