EARMOR M31H PLUS ARC Helmet Rails

EARMOR M31H PLUS ARC Helmet Rails shooting earmuffs provide advanced electronic hearing protection designed for shooting ranges, tactical use, and high-noise environments. Two directional microphones capture ambient sound and reproduce it inside the ear cups. Harmful impulse noise above 82 dB is automatically suppressed, while low-level sounds such as speech or movement are amplified.

The PLUS version introduces several upgrades over previous models, including an improved Dynamic Voice Tracking module for clearer speech recognition, updated internal circuitry, enhanced resistance to radio interference, and new silicone gel ear cushions for increased long-term comfort. A 3-second power-off delay prevents accidental shutdown, and the battery compartment has been reinforced.

The M31H PLUS model features ARC rail mounting for tactical helmets. It is not a communication headset and does not include a radio microphone. It offers a 3.5 mm AUX input for connection to external audio devices such as smartphones or music players.

Low-profile ear cups allow comfortable aiming, while the foldable design makes storage and transport easy. Powered by two AAA batteries, the unit features automatic shut-off after 4 hours.
