The Earmor M31H MOD4 is the helmet-mounted version of Earmor's M31 electronic hearing protector. It attaches to ARC-style side rails on FAST-type high-cut helmets, so you get hearing protection without a headband under the shell. The cups swivel up off the ear when you don't need them.

- Mounts to ARC-style helmet side rails, no headband needed
- Electronic sound amplification with automatic cut-off for loud impulse noise
- Manufacturer-stated noise reduction: NRR 22 dB

Important information
Noise reduction ratings are manufacturer-stated (US NRR scale) and have not been independently tested by R Supply Store. Real-world protection depends on fit, and is reduced by hair, glasses and helmet straps under the seal. Hearing protection lowers noise exposure; it does not remove the risk of hearing damage. Keep the volume of amplified sound and radio audio at a comfortable level.
Delivery
Ships directly from our manufacturing partner's warehouse in China, not from a UK warehouse. Most orders leave within 2 working days of payment and delivery usually takes 10 to 15 days. UK delivery is £5.50 on orders under £75 and free on orders of £75 or more. If you order items from more than one manufacturer, they may arrive in separate parcels. Full details are in our shipping policy.
