These are the best passive hearing protection I’ve ever found. I wore out the older ones and got a pair of the 31db ones (mine are black). They use some sound channeling technology (all passive) to just kill all the higher pitch stuff. Really amazing. I can still hear the music playing in the shop when most tools are running. Has something to do with which frequencies it filters out…black magic, but they’re pretty amazing. And no batteries to worry about!!
