EARMOR M31 PLUS Electronic Hearing Protector – Active Earmuffs with Gel Pads & AUX Input The EARMOR M31 PLUS is a rugged electronic hearing protector built for players who want real hearing safety without losing awareness on the field. Designed to amplify safe ambient sounds (voices, callouts, movement) while automatically suppressing harmful impulse noise, the M31 PLUS is a top choice for airsoft milsim, outdoor skirmishes, and loud CQB environments where communication and comfort matter. What makes the M31 PLUS a field-proven upgrade Active impulse protection: suppresses loud noise above 82 dB with a super-fast response (under 1 ms) to protect your hearing. NRR 22 dB / SNR 29 dB: certified passive + electronic protection for safer sessions. Gel ear cushions: improved seal and comfort for long games, even with goggles straps and helmets. Low-profile cups: less interference when shouldering rifles and moving in tight CQB lanes. 3.5mm AUX input: plug in compatible devices for audio input (ideal for training or simple wired comm setups). Smart power saving: 4-hour auto shut-off helps prevent battery drain in your kit bag. Weather ready: IPX5 splash resistance for rainy, muddy game days. Built for airsoft scenarios In CQB, the M31 PLUS keeps your ears protected while still letting you hear the details that win rounds—door taps, footsteps, and quick callouts. Outdoors, the amplified ambient sound helps you keep track of teammates and movement across vegetation without constantly lifting your ear pro.
