Not cheap, but custom in ear work well. I use a system called cens, imported by Westone and sold under defendear. There are other options, but expect about $1k or so.
I use the walker also. My ears got rung last year and couldn’t hardly hear out of the right side for a few days so I bought the walker. So far I really like them.
Sordin Supremes with gel cups are the most comfortable and true to life sound. Definitely much better than walkers or Howard leight impact sports for sound and comfort.
The one thing with the walkers is that they pick up a lot of wind noise, so much so that I would take them out. You don’t get that with Soundgear Phantoms

I have been happier with these than over the ear electronic muffs. I find I can’t blow a call with the electronics but I can with these. The decibullz allow a little better background hearing and conversation then the surefires.
I use the walker razor electronic muffs, I usually go through about 15-20 boxes a year during bird season and I don't need the hearing damage. They work great, and I hardly notice they're there. Also HUGE pro is they can be found on sale at cabela's for as low as $50 (cad) sometimes
