Earmor M31N-Mark 3 MilPro Active Hearing Protectors - Black

Active hearing protectors designed for use in environments with high noise levels, equipped with a noise reduction system down to 82 dB. The M31N Mark 3 model provides effective acoustic protection while still allowing you to hear sounds from your surroundings.

Two directional microphones mounted on the outside of each ear cup capture sound signals, which are then played through speakers inside the ear muffs. The design lets you maintain situational awareness without needing to remove the hearing protectors.

Automatic limitation of noise when exceeding 82 dB serves as protection, ensuring hearing safety at (NRR) 22 dB. At the same time, quieter sounds are amplified depending on the selected mode, making conversations easier and allowing for better control of your surroundings.

Fast-responding electronics deliver a reaction time of less than 1 ms, so the system responds instantly to sudden volume changes, protecting against harmful noise impulses. The protectors allow you to choose from 5 work modes and adjust settings to current conditions.

Black ear cups made from solid polymer with a 3 mm thickness deliver outstanding resistance to mechanical damage. IP67 certification guarantees superior dust and water resistance.

A specially designed headband provides even pressure distribution, keeping the protectors stable on your head and comfortable for extended wear. The MIL-STD-416 standard certifies the design’s readiness for use in harsh conditions.

Automatic shutoff after 4 hours of inactivity helps conserve energy. Powered by 2 AAA batteries, the construction features safeguards to prevent accidental shutdown.

A waterproof battery compartment and securing loops for the caps reduce the risk of losing them. The device’s compact size makes it easy to transport and convenient to store in your gear.

A built-in 3.5 mm AUX port and included cable let you connect external devices like radios, phones, or audio players. You can listen to messages or sounds directly through the hearing protectors, eliminating the need for additional headphones.

The set is suitable for helmet mounting. It also comes with a hook-and-loop mounting kit so you can attach the protectors directly to, for example, a cap.
