To add to this, the cool thing about musician’s earplugs is they try to attenuate the sound in a way that roughly conforms to the equal loudness curve. It isn’t perfect (the highs are often still knocked down more than I would like) but in general they are way better than normal earplugs which basically just kill most of the mid to high range. If you want to make sure you get custom moulds done right, a local audiologist can do it for you. Walking out of a concert (or for me a gig - I used to play the drums professionally) popping out your plugs and having your head feel totally normal is such an amazing feeling! Highly recommend them even if you only go to a handful of loud venues in a year.
