I went to an audiologist and had a set of plugs custom molded to my ears. Cost was 60 bucks but I have5
used them 6 years now. They are soft silicone easily washable come with both attached to a lanyard which i loop on a dedicated ball cap.
I do shoot lots of trap
Audiologists recommend under 80 decibels but with these plugs i am under 40 or less.
