I had the opportunity to use them in 2025 for about a month and they really performed well. Paradoxically, they were more comfortable than the Peltor Sporttacs. The noise reduction was also flawless, so I can easily recommend them :)

Lightweight active hearing protectors featuring low-profile ear cups, designed for use by sports shooters, military personnel, and other uniformed services. Perfect for both training at shooting ranges and deployment in combat zones, the ear cup shape ensures comfortable fit for both left- and right-handed users. Certified according to the American NRR standard, they provide effective sound attenuation of 22 dB.
Along with a traditional, adjustable, and padded headband, this model is fitted with a dedicated M16 mounting kit for ARC-type helmet rails. The 360-degree rotating structure increases comfort when used with helmets.
Equipped with two covered, omnidirectional microphones for high-frequency environmental sound detection, audio is then transmitted to internal speakers. Low-level noises are amplified, while loud sound spikes—such as gunfire—are suppressed to a safe 82 dB within 0.001 seconds. The set includes an AUX 3.5 mm audio cable, allowing connection to external devices like mobile phones or radios. The headphones offer five-level volume adjustment and a locking mechanism to prevent accidental power-off.
Earmor M31X Mark 3 meets MIL-STD-416 and MIL-STD-810G military specifications. The inner components are sealed against moisture and dust in compliance with IP67 rating, providing protection against submersion in water up to 1 meter for up to 30 minutes.
Powered by two AAA 1.5V batteries, an efficient power management feature automatically switches off unused protectors after 4 hours. Battery compartment caps are secured with silicone loops to prevent loss.
A folding construction allows for compact storage and easy transport in the included carry case.

They're pretty good, I mainly use them at an indoor shooting range and the difference is significant. They dampen sounds well, and I can still hear what the guys next to me are saying. Comfortable even after sitting in a helmet for a long time, nothing squeezes or moves around. I can easily recommend them, they muffle the AK on the next spot and that's something.

J... Review confirmed by purchase
The product looks like a Chinese counterfeit, and on top of that, costs a fortune. The mount is made of tacky, easily deformable plastic, so it easily falls out of the helmet's mounting rails (ballistic, not Airsoft, just to be clear) whenever you try to tilt the headphones back. The mounting is so shoddy that the locking tab for movement on the rail doesn’t catch at all. When you turn them on, the headphones just make a “beep” and “pop” sound when you press the buttons, but otherwise behave like passive headphones—no amplification at all. Even at the maximum amplification level, they work the same as the cheapest junk from a hardware store. For comparison, I have the M31 Earmor, and next to those, this is clearly a non-functioning (except for the beeping) Chinese dummy.
