I'm not entirely sanguine about the "earbud" hearingpro out there.
Yes, I understand the physics for noise cancelling, and that tiny speakers at fractions of a watt are magnitudes less than gunshots.
But, you are asking a lot of those with regard to fit.
And fit is important, as it's generally good to try and isolate how much sound gets passed via the anatomy near the ears.
And I'm very bearish on buying things off Amazon, as there are just too many drop shippers on the site anymore. If I find a thing searching on Amazon, I usually try and find the actual manufacturer and source things direct. Which can be disappointing when it turns out that Manufacturer X does not, in fact, make Product Y, or discontinued it or some such.
Now, my Howard Leight Sport has a jack so that a person can pipe in music or the like. I've used that on planes to some good effect. I'm old fashioned enough to not want music in my ear while shooting. Perhaps that is from being shouted at by professionally permanently-crossed persons at military ranges with highly inventive profanity. Any of that "leaking out" while at a public range might raise and eyebrow or two.
