Kerbl Level-Dependent Ear Muffs, SNR 31 dB with Microphone

Level-Dependent Ear Muffs – hear clearly, stay protected

These level-dependent ear muffs from Kerbl protect your hearing during loud work while keeping you connected to your surroundings. The built-in microphone picks up speech and signals in the 400–4000 Hz range, so you stay in contact even with the muffs on. Perfect for farmers, tradespeople and hunters working around noisy machinery.

Once the outside noise level exceeds 82 dB, the automatic level limiter instantly reduces the sound to a safe level, protecting your hearing without needing to remove the muffs. Used as standard hearing protection, they still deliver an attenuation of 31 dB (SNR). The soft, padded headband stays comfortable through long shifts in the yard, field or workshop.
