I use the silicone molded plugs that you have to "screw" into your ears. They are molded in place. Granny made me my first set at a big NSCA tournament in '03. I can hear conversations just fine with them in, so I never felt the need for electronic ones.
Cabela's used to sell a kit with which you can make your own, with someone's help.
I suffered most of my hearing loss very young, due to a boil in one inner ear, then working in a fighter jet squadron in the Navy, and lastly from driving tractors without a cab for so many years. I do not believe I have suffered much hearing loss in the last 19 years since getting custom molded ear protection.
