Product Description

Noise-proof and noise-reducing earmuffs for use with V-type helmets.
The helmet mount version can be mounted directly on many industrial safety helmets without the need for additional accessories.
A high-density foam pad that provides a high-quality, low-noise seal for the wearer's comfort.
This protection is based on a two-shell technology that minimizes resonance in the enclosure for optimum high frequency attenuation.
The acoustic connection between the inner and outer casings provides maximum low frequency attenuation.
Sealed ring width filled with a high density sponge for optimum fit and reduced contact pressure.
