This is what I've come up with. My goal is for a limited use with an extremely obnoxious gun, to be tamped down to "my ears didn't ring afterwards/I shot it indoors without losing hearing" without killing situation awareness. This means a mag or two, not an all-day range affair, which I double up with foam/muffs for.
Is there a better option? Will this leave me disappointed? Amazon seemed to give it some legit reviews, the only complaint being a few people "lost it in their ear" due to the short stem, which sucks, yes, but it's not like surgery was required, just a friend and some tweezers, and I am not sure how high functioning said people were, or not, but the product has been around since 2015 so likely they aren't being sued to death for it.
I did look at the Surefire Sonic Defenders, but they seemed pretty "meh" in comparison.
