Earmor M31 MARK4 Active Hearing Protectors - Black
Active hearing protectors designed for use in high-noise environments, equipped with a noise reduction system down to 82 dB. This model provides effective acoustic protection while still allowing you to hear ambient sounds.
2 directional microphones mounted on the outside of each earcup capture sounds, which are then played back through speakers inside the hearing protectors. This solution allows you to maintain situational awareness without needing to remove the headset.
level of noise attenuation, fast response time
The model automatically limits noise when it exceeds 82 dB, providing protection at a level of (NRR) 22 dB. At the same time, quieter sounds are amplified according to the selected work mode, which makes conversations easier and improves control over your surroundings.
The electronics used operate extremely quickly - a response time of under 1 ms means the system reacts almost instantly to sudden changes in sound intensity, suppressing dangerous impulses. The protectors offer 5 work modes for adjusting their operation to the current conditions.
damage-resistant construction
The black earcups are made from durable, flame-resistant polymer with a thickness of 3 mm, providing high resistance to mechanical damage. The model meets the IPX5 standard, ensuring protection against water jets from various directions with an intensity up to 12.5 liters per minute.
The headband design allows for even pressure distribution, resulting in a stable fit on the head and comfortable wear over extended periods. The MIL-STD-810F standard confirms that the headphones are suitable for demanding conditions.
battery powered, automatic shutoff
Automatic shutoff after 4 hours of inactivity reduces energy consumption. The device runs on 2 AAA batteries, and its design includes safeguards to prevent accidental shutdown.
This model is equipped with a waterproof battery compartment and retention loops for caps, reducing the risk of losing them. The compact design makes it easy to transport and store in your kit.
U-174 plug
The model is fitted with a U-174 plug compliant with NATO standards, compatible with military equipment.
