Just lost my favorite pair of earplugs, bought through the old Brookstone catalog some years back. No longer carried. They were rubber with a small hole in a metal core. let in most sounds but baffled the big ones.
Worked for years without hearing protection, got smart as I got old; now I can’t stand to work without. Even wear them to the table when the grandkids come.
So where have you found some good ones? I really hate the small fiber twist-in throw-aways.
