I explored similar solutions but recently switched from AirPods Pro to AirPods Pro 2. I was genuinely surprised by how much better the noise canceling was for my needs, such as working in the office and doing yard work. Last night, I used them at a sporting event where loud techno music was playing, and I could hardly hear the music while clearly listening to my podcast. Proper fit of the earbuds is absolutely key and AirPods don't match everyone's ear shape, so YMMV.

i've fantasized about some kind of external noise cancelling system for use at a gun range. It would be nice to have something that would make it bearable to be behind someone shooting a firearm without ear protection. btw, you know in action movies when there's 10 people with automatic weapons shooting it out in a building and talking to each other? yeah.right. firearms are so unbelievable loud, there's no way any conversation is happening in that environment. further, video doesn't do the supersonic blast justice at all it's something you have to experience.

  AIUI, active noise cancelling doesn't really work well for impulsive sources like gunshots because the impulse does not exist for enough time for predictive interference to function. Additionally, because noise cancellation depends on the phase of the wave relative to the receivers (your ears) it really needs to be within ~1/4 wavelength of your ears, or 3" at 1kHz. In gun ranges, what you would probably benefit most from is passive energy reduction, so ear protectors (already usually covered) and acoustical treatment. However, acoustical surface is very expensive where flat concrete is cheap, so you end up with gun ranges being big reverberative spaces instead.

    Not that this would be practical but could you connect the gun to a speaker and just play the inverse of a pre-recorded gunshot? You'd need to have lots of pre-recorded shots as I imagine there's some variation between guns, calibers, etc. but I wonder how well it could actually work.

    The firearms headsets I've seen use a form of noise cancelling that is an electronic limiter that closes immediately upon excessive noise, so impulse noises like popping and crackling don't reach your ears. But otherwise, you can hear just fine (voices, even the wind).
