The Peltor Optime III earmuff is designed for extremely noisy environments, especially those dominated by high frequencies. It provides protection based on dual resonance minimization technology at the base of the housing, which results in maximum attenuation of high and low frequencies. It is available with headband support, neck support, helmet support, but also in green HiViz coloration, where visual contact with the user is required in difficult conditions, for example on road construction sites, airports or other high-risk work areas.
