If you look at Wildear or SportEar, they are at the $1k mark or well above. I was actually looking at the SportEar, and getting it tuned to my particular hearing loss since they can do that on some models. It certainly would have solved a lot of my issues. I eventually gave up as they were not responsive to requests for information. Too bad for them since I had the money in hand and was ready to purchase some high end models. When you pay upwards of $6000 for a set of hearing aids every 5 years, the cost for good hearing protection doesn't seem so bad.
The reasoning behind the 25dB minimum rating is that anything less than that and it will start my tinnitus ringing, badly. The hard part is those at, or over that rating, tend to be large and do not work well for shooting rifles and shotguns. The Howard Leights may work out, but I am fairly sure I would need to double plug, at least when I am shooting. Or I go to a system where I am wearing the active hearing only when I am not shooting, and plug up when I am.
