This option is expensive, but I bought Sport Ear (now Axil) custom fit electronic earbuds (former hearing aid manufacturer) a few years ago. They're tuned to compensate well for my heavy loss of high frequency hearing (due to 50+ years of shooting). They're also reprogrammable if my hearing changes over time. They were somewhere under $3000, through a deal at FrontSight when I was there (hearing frequency response test, custom ear canal molds, tuning). I also got the waterproofing treatment. They have several modes, including amplification with spike attenuation (eg gunshot) which is great for hunting or at the range. They also have a background noise cancel mode, so I can actually hear someone for a change, talking right at me in a crowded noisy room. I have a couple pairs of walker low profile muffs and game-ear buds, lots of foam and silicone buds (surefire, etc), but the Sport Ears easily work best for me. Great auditory performance and protection, very comfortable for all-day wear, unobtrusive (won't get knocked loose at just the wrong moment with recoil like muffs). I feel it was worth the large investment for me, and may be for you if you do a lot of hunting and shooting. Just something to consider.
