with the little foam plugs inside the muffs, but I wasn't at it that long. Unbelievable how loud those speakers can go, especially since my prior (and concurrent) speakers are 4" single driver backhorns that start to compress above about 5 watts input, maybe 98-99 db. BTW there's a hearing protector set hanging from the steering wheel of my lawn tractor, one in the shop, and I wear a lightweight set around my neck at work just because I like to be able to listen to stuff of my own choosing.
