The
principle, if that's what you're asking about, works fine in my electronic earmuffs at my indoor range. I imagine the
principle, that is, electronically shutting down the amplifiers at the instant a louder noise occurs, can't be much different in these.
Differences will be in the sound cutoff levels, response time, etc.
With my muffs, I can hear conversations, range orders, etc with no problem, and in stereo, but when a shot occurs (or you even tap the muffs with a fingernail), the amplification level drops instantly, and then takes maybe 1/4 second to come back up.
The only problem is remembering to shut them off when I put them back in the range bag. My earmuff style uses regular AAA batteries, so replacing the batteries is easy and inexpensive. If these use "button-type" batteries, it may be less convenient and more expensive to replace them. However, mine work fine as "regular" muffs even if the batteries are dead, and I would guess the same thing is true of these.
FWIW,
