Gerber Electronic Ear Muffs Black Auto Cut Off Over 82dB

Gerber Electronic Ear Muffs – Auto Cut-Off Hearing Protection (NRR 21dB, Class 3)

Stay alert. Stay protected. Designed for shooting, hunting, and noisy environments, these intelligent earmuffs amplify ambient sounds while automatically cutting off dangerous noise above 82dB.

Gerber Electronic Ear Muffs combine advanced auditory technology with rugged comfort. Dual omni-directional microphones pick up environmental sounds and amplify them up to 4–5× for improved awareness. When the noise level exceeds 82dB—such as gunfire or machinery—the auto shut-off feature activates instantly to protect your hearing.

Soft ear cushions and a padded, adjustable headband ensure a snug fit for extended wear, while independent electronics in each ear cup deliver consistent, high-performance protection.
