I've tried plenty of ear plugs for sleep, loud environments, and concerts. I'd stay clear of anything that's clearing putting most of the money into marketing like loop and talk to a audiologist or someone in the music industry. I ended up getting mine from "1of1 custom"[1] based on some research and references. They're a bit pricey, but based on the amount of loud environments I'm in they're literally life savers. I pair it with a sound level app made by NIOSH to let me know when I should put them in at bars/concerts.
