These earmuffs have been developed for use in extremely high noise environments, particularly those dominated by low frequency sounds. The protection is based on a technology with a double casing, minimising resonance in the holder casing resulting in maximum high frequency attenuation.

• Broad sealing rings filled with soft plastic foam for optimum fit and low contact pressure
• Good speech intelligibility
• Easy to replace cushions and inserts help keep them hygienically clean
