The Moldex M4 Ear Defenders are robust, high-quality ear muffs for work in noisy conditions. They give high attenuation with an SNR of 30 dB, which helps protect your hearing during long periods of exposure.
A particularly low profile keeps the cups close to the head. A light, flexible build with low contact pressure makes them easier to wear for long shifts.
