M31H PLUS Electronic Hearing Protector, Helmet Mount - Coyote Brown

EARMOR M31H PLUS Electronic Hearing Protector – ARC Helmet Mount Active Ear Pro (NRR 22)

The EARMOR M31H PLUS is a helmet-ready electronic hearing protector made for players who run FAST/ARC rail helmets and want real protection without losing awareness. It amplifies low-level sounds like voices and movement, while limiting harmful impulse noise above 82 dB—ideal for CQB, outdoor skirmishes, and long milsim events where clear callouts and safety matter.

Key advantages for airsoft & milsim

• Helmet mount ready: pre-installed ARC-type helmet adapters for FAST/OPS-CORE style rails (stable fit, no headband pressure).
• Active hearing protection: NRR 22 dB to help reduce noise exposure while keeping you aware.
• Impulse limiting: suppresses dangerous peaks above 82 dB for safer play around loud bangs and pyrotechnics.
• Dynamic Voice Tracking: improves speech pick-up so team callouts stay clearer in noisy environments.
• 2024 PLUS comfort upgrade: gel silicone ear cups for better sealing and less overheating during long sessions.
• Foldable low-profile cups: easier rifle shouldering and compact storage in your kit bag.
• 3.5mm AUX input: connect a phone/MP3 (audio input) for simple wired listening between games.
• Auto shut-off: powers down after 4 hours to help save batteries.
• Weather resistant: IPX5 splash protection for rainy or muddy game days.

Important note (comms vs. hearing protection)

The M31H PLUS is an electronic hearing protector (no boom microphone and not a PTT/radio communication headset). If you need full radio comms with mic/PTT, choose a dedicated communication headset model.
