Earmor M31N-Mark 3 MilPro Active Hearing Protectors - Black

Active hearing protectors designed for use in high-noise environments, equipped with a noise reduction system down to 82 dB. The M31N Mark 3 model delivers effective sound protection while still allowing awareness of ambient sounds.

Two directional microphones mounted on the outside of each ear cup pick up sounds, which are then played back through speakers inside the ear protectors. This design allows you to maintain situational awareness without removing the headset.

The model automatically limits noise above 82 dB, providing a protection level of (NRR) 22 dB. At the same time, quieter sounds are amplified according to the selected work mode, which makes it easier to hold conversations and improves situational control.

The onboard electronics operate extremely fast – with a response time of under 1 ms, the system reacts almost instantly to sudden changes in sound intensity, minimizing hazardous impulses. The protectors offer 5 work modes, letting you adjust to current conditions.

The black ear cups are made of durable polymer with a thickness of 3 mm, providing high resistance to mechanical damage. The model meets the IP67 standard, ensuring protection against dust and water.

The adjustable headband is designed to distribute pressure evenly, ensuring a stable fit on the head and long-wearing comfort. The MIL-STD-416 standard confirms suitability for use in demanding conditions.

Automatic shut-off after 4 hours of inactivity helps conserve energy. Powered by 2 AAA batteries, the design includes safeguards against accidental shutdown.

The model features a waterproof battery compartment and retaining loops for the caps, reducing the risk of loss. The compact design makes it easy to transport and store with your gear.

The built-in 3.5 mm AUX jack and included cable let you connect external devices such as radios, phones, or audio players. This way, you can receive messages or audio directly through the protectors without needing extra headphones.

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