I got custom-molded ones from my audiologist; custom-molded earplugs for musicians would be the gold standard, I should think.
Best ear plugs for both sound quality and reduction
Any recommendations for ear plugs used mainly for live music? Not alot of info on the interwebs.
Etymotic, Eargasm, Vibes, Hears all seem OK but like anything audio, it's about fit. (In this case literally) Other solution is getting a custom one made from an audiologist.
