EARMOR M31H PLUS electronic hearing protection for helmets

EARMOR M31H PLUS – Advanced Hearing Protection for Tactical Use

The Electronic Hearing Protector M31H PLUS from EARMOR provides high-quality hearing protection, reducing harmful noise while keeping ambient sounds audible. These active hearing protectors are essential in high-noise environments, such as shooting ranges, where prolonged exposure to loud noise can cause permanent hearing damage.

Advanced Technology for Optimal Protection

The M31H PLUS uses two directional microphones to capture ambient sounds and reproduce them through internal speakers. This allows the user to remain aware of their surroundings without compromising hearing protection. Harmful sounds above 82 dB are automatically reduced to safe levels, while quieter sounds are amplified.

Note: The M31/M31H PLUS is intended solely for hearing protection and audio reception via a 3.5 mm AUX connection. This model has no microphone and does not support communication via radios or transceivers (unlike the M32 PLUS).

PLUS Version Improvements (compared to MOD3 series)

Introduced in 2024, the PLUS version includes several technological and ergonomic upgrades:

- New threaded attachment for easy removal of earcups from the headband

- 3-second shut-off delay to prevent accidental power-off

- Silicone battery holders for extra stability

- Reinforced metal battery cover for improved durability

- Optimized Dynamic Voice Tracking for better speech recognition and amplification

- Improved radio frequency interference protection

- High-quality earcup materials for enhanced durability

- New gel silicone ear cushions to prevent overheating and provide long-term comfort
