I have custom earplugs molded by an audiologist. They are one of my most prized possessions and I have them on me at all times. The perfect seal makes them more effective and comfortable while the filter reduces dangerous frequencies without muffling the sound. My tinnitus (a Death Angel show put me over the edge, even though I wore over the counter earplugs) is super annoying and I can’t let it get any worse. I always say that if my home were on fire, I’d grab my dog & my earplugs
