Electronic Ear Protection M31 PLUS SET by EARMOR

The M31 PLUS electronic earmuffs from EARMOR provide premium hearing protection, allowing you to shield your hearing from harmful noise while still hearing your surroundings. Featuring built-in active hearing protection, these muffs are perfect for high-noise environments such as shooting ranges, where you're exposed to hazardous sound levels that could cause permanent hearing damage. They operate via two directional microphones and internal speakers, allowing ambient awareness while keeping dangerous sounds below 82 dB and amplifying quieter sounds like speech.
The M31/M31H PLUS versions are dedicated to hearing protection and audio input only via 3.5 mm AUX jack and do not feature a microphone—they are not headsets for communication via radio or walkie-talkie (unlike the M32 PLUS).
Produced by EARMOR, now recognized as a manufacturer of military-grade communication systems like the MARK3 headsets, their products are known for quality, durability, and compliance with strict military standards. This set includes a classic headband for standalone use and ARC rail helmet adapters compatible with FAST, MICH, and AirFrame helmets.
