Earmor M31 MARK4 Active Hearing Protectors - Black
Active hearing protectors designed for use in high-noise environments, equipped with a noise reduction system up to 82 dB. The design effectively protects your hearing while still allowing you to hear ambient sounds.
2 directional microphones placed outside each earcup pick up surrounding sounds and transmit them through speakers inside the hearing protectors. This solution helps maintain situational awareness without having to remove the hearing protectors.
High level of noise reduction and lightning-fast reaction time
The automatic noise reduction mechanism activates when sound exceeds 82 dB, ensuring hearing protection at a level of (NRR) 22 dB. Lower-level sounds are amplified according to the selected work mode, making communication easier and allowing you to effectively monitor the environment.
Advanced electronics provide an ultra-fast reaction time - under 1 ms - allowing you to almost instantly neutralize sudden volume changes and eliminate dangerous sound impulses. The user can choose from 5 work modes to optimize functionality depending on the conditions.
Durable construction resistant to damage
Black earcups made from tough, fire-resistant polymer with a thickness of 3 mm boost resistance to mechanical damage. This model complies with the IPX5 standard, offering protection against water jets from various directions with an intensity up to 12.5 liters per minute.
A specially designed headband ensures even pressure distribution on the head, securing a stable fit and maximizing comfort even during prolonged wear. The MIL-STD-810F standard confirms the headphones are built for rugged field use.
Battery powered with automatic shut-off feature
Automatic shut-off after 4 hours of inactivity helps conserve energy. The device is powered by 2 AAA batteries, and the design is protected against accidental shutoff.
Water-resistant battery compartment and loops for securing the caps minimize the risk of losing them. The compact build makes it easy to carry and store with other gear.
U-174 plug
The set includes a U-174 plug made to NATO standards, compatible with equipment used by the military.

MIL-STD-810F standard specifies test requirements for military equipment, including metal detectors, to ensure their reliability in extreme environmental conditions. Tests include resistance to extreme temperatures, humidity, shock and vibration, among others. Metal detectors that meet this standard are guaranteed to work in harsh operating environments.
