    I wouldn't consider them at all. They're not going to offer as much noise blocking as a pair of electronic head gear. And decent head gear isn't very expensive these days. You can get very good to excellent hearing protection for well under $50.

    I much prefer electronic hearing protection.
    Here's a link to a few choices at Sportsman's Guide

    The Caldwell muffs: Caldwell E-Max Electronic Earmuffs, Standard - 201336, Hearing Protection at Sportsman's Guide

    I wear Caldwell ear muffs. They work extremely well. I shoot a 50 BMG rifle and have never had my ears ringing from the shots with the 50 with those muffs on.

    Don't risk your hearing on these. Get something approved by OSHA (eg. Peltor 105 $30) and wear earplugs with them.

    Electronics muffs do not offer additional protection. They just allow ambient sound to be heard when a shot is not being fired.
    When a shot is detected, the circuitry cuts out the allowed ambient, but does not electronically cancel the shot noise.

    If you look at the NRR you will see no extra protection. If you really want something extra, put in those spongy ear plugs under your ear muffs.

    The plugs are a good idea. As for the OSHA, if two earmuffs are equal and one has OSHA approval, it just means that the price is higher because they had the added cost of the approval cycle.
    Same thing happens to organic farmers. Here in NC, they use the term "morganic" meaning organic, but not approved by a bureaucrat.

    Noise cancelling tech (as opposed to just muffling it) actually generates a reverse sound wave to the incoming one. Idea is the waves cancel each other out. Heard where they tried using the tech to replace a muffler - put the microphone up close to the headers, and the speaker near the end of the pipe. Computer speed was a major factor - idea was by the time the sound pulse reached the speaker, the computer had calculated the inverse wave. THey claimed it purred quietly, barely audible. But the tech costs many times what a muffler does, plus I wonder if the sound through the pipe is affected by RPM and exhaust velocity.

    Thinking for shooting, the intensity of the inverse wave needed to cancel the gunshot is (1) too high for a small device like that and (2) can it compute the inverse and emit it fast enough to cancel the sound before it enters your ear....

    I went to Home Depot and got some regular muffs with a NRR in the mid 30's - not expensive but also no good for rifle shooting as it disrupts the cheek weld contact. They are bulky! But they WORK!

    The electronic earmuffs don't (and do not claim) to cancel.

    I am quite familiar with noise cancellation technology from my working days.
    If the sensor were about 1" from the ear, there would be about 10 microseconds to produce an inverse of the shot waveform and then digitally cancel it.
    Not likely in an affordable consumer product. It would perhaps be possible to have a stored approximation to a generic gunshot sound and use that to some benefit. I haven't seen this product. An analog cancellation circuit to reduce the lower frequency components of a shot might be feasible. Unfortunately, a gunshot has a broad frequency spectrum (typical of any impulse like sound).

    I think I will look at Home Depot. NRR in the mid 30's is better than what is sold at my range.
    Thanks for the suggestion,

    I have inner ear issues that make earplugs a sure ticket to an inner ear infection, so I use hard muffs. I agree they shouldn't be scrimped upon. Good ones do provide good protection. I have used hard muffs exclusively since 1980, and my hearing is acute enough to necessitate using a white noise generator to not be woke up 3-4 times a night by dogs or birds, etc. I'll turn 60 in September.

    I did forget to mention that I do were mini plugs in my ears as well. The two together works very well for me.
