This for me, too.
Too many years of too many gunshots, unprotected. I bet just from ONE .300 Win Mag that I used to shoot A LOT, my ears have taken in 500-750 unprotected blasts from that one gun. My ears ring non-stop now.
Today...………. I wear ear protection shooting anything but a bow or an air gun. Tractors...……….chainsaws...…….leaf blower...……..power tools...………. All of them.
