Peltor X5P3E Hard Hat Mount Earmuffs

3M PELTOR X5 Earmuffs are designed for very high noise situations, offering a Noise Reduction Rating (NRR) of 31 dB for both headband and hard hat-attached models. The high attenuation provided by these earmuffs is a result of the combination of specially-formulated foam in the earcups and cushions and the innovative spacer and cup design.
