Electronic Hearing Protector M31 PLUS by EARMOR are top-notch hearing protection that allows you to protect your hearing from dangerous noise while still hearing ambient sounds.
These earmuffs with active hearing protection are invaluable in environments with high noise levels such as shooting ranges, where you may be exposed to excessive noise and face health risks of permanent hearing damage.
The functioning principle is that sounds are captured by two directional microphones and reproduced by speakers inside the earmuffs.
This allows the user to hear the surrounding environment and protect their hearing simultaneously.
Harmful noises are limited to a safe level of 82 dB, while lower-level sounds are amplified.
Thus, the M31 PLUS version is only earmuffs for hearing protection and audio reception via a 3.5mm Jack AUX connector, not a headset with amicrophone, meaning they do not enable communication through radios or transceivers (unlike M32 PLUS).
The PLUS model brings several enhancements compared to the previous version MOD3. For example, new gel silicone ear cups (ear pads) that increase comfort during long-term wear.
The PLUS version (introduced in 2024) is also equipped with cutting-edge technologies ensuring even better listening properties.
List of enhancements in the PLUS version compared to MOD3:
- New threads for easy detachment of earmuffs from the headband
- 3-second button delay to prevent accidental shut-off
- Silicone retainers for battery covers
- Improved metal battery cover
- Revised Dynamic Voice Tracking module (speech recognition and amplification)
- Increased resistance to radio wave interference
- Improved materials of ear cups (ear pad housings)
- New gel silicone ear cups (ear pads) (prevents ear overheating)
- New updated circuits and dynamic microphones
