3M Hard Hat Attachment Format Earmuffs H520P3GS/E

3M PELTOR Optime II Earmuffs H520P3GS/E have been developed for demanding noise-hazard environments. A perfect choice for environments with substantial industrial noise or construction machinery, like airports and agricultural work.

Multiple adaptor options are available for compatibility with a wide selection of helmets. These helmet mounted earmuffs in classic green reduce noise levels up to 29 dB. The large space inside the cups helps reduce heat and moisture build-up, and the soft, wide cushions help decrease pressure around the ears, making them comfortable to wear for long periods. The cushions and foam inserts, available as Hygiene Kits, are easy to replace if they become worn or damaged, extending the life of the product. 

Compatible with 3M 25 mm hardhats and visors. Also includes 30 mm hard hat adapter.
