I bought the Axil XCOR Bluetooth earplugs ($188 after disc, 21-23nrr) after seeing it advertised on Facebook a lot. I prefer plugs over muffs for comfort, and have used the SportEars custom plugs ($1200, 29nrr) and 3M EEP100 w/skullscrews ($250, 23-30nrr) in the past.
The XCOR regular price is $199 and $299 with Bluetooth and there are regular discounts of 30 to 40% off. It comes with a charging battery case, silicone tips 21nrr, foam tips 23nrr, and USB C charging cable.
The charging case is small and easily fits in a pocket. The plugs are a bit in the larger side but fit comfortably and stay in well. You could wear them all day with no problem. These are rated for 12 hours of hearing control, 6 hours Bluetooth only, and 4 hours of hearing and Bluetooth. These ratings seem accurate with my use and 12 hours is more than enough to get through an extended range day.
These do an adequate job of blocking gunfire at the outdoor Koko Head bullseye pistol range. I haven't tested the XCORs at an indoor range yet, but I'd expect the 23nrr is just enough for standard pistols, and anything more powerful would require doubling up. My old 3Ms 30nrr was usable just by themselves at indoor ranges with the exception of muzzle brakes and the most powerful calibers.
The XCOR filters down loud noises which is better than cutting off all volume that cheaper stuff does, like the popular Howard Leight muffs. However It does so noticably with a slight lag to return to normal volume. Not bad, not great. My SportEars did the same magically where you didn't notice it filtering. The 3Ms cut off all sound for a split second which is a bit jarring.
The hearing enhancement is adequate. There are 3 levels of enhancement from 1x, 2x, and 6x. It performs as expected amplifying soft sounds and speech is clear. However there is white noise from a soft hiss at 1x that you'll ignore after a short time but it gets louder at 6x where you probably won't use it. I've found nothing that tops my old SportEars which were crystal clear and I could hear conversations at the other end of the firing line. They were basically hearing aids that blocked sound. My 3Ms were poor in comparison with speech a bit muddied and the max amplification was about 1.5x..
I like having Bluetooth on my muffs/plugs as I use a shot timer app on the phone. I don't bother other shooters next to me. The volume is loud. Sometimes I'll listen to podcasts and the speech is clear. The microphone for taking phone calls is just usable. Music quality is just adequate with weak highs and lows.
Overall they're a good value for what they cost. I just wish the NRR was higher. It is a good improvement from my 5 year old 3Ms, but still nowhere near the performance of my 15 year old SportEars.
