3M™ PELTOR™ OPTIME™ II HEAD BAND H520A EAR MUFF CLASS 5  32 DECIBEL Developed for demanding noise-hazard environments with increased low frequency attenuation, these are a suitable choice for environments with substantial industrial noise or construction machinery, like airports and agricultural work. The headband is the same strong padded comfortable version as standard in the Optime™ range. Versatile protection for both short and long duration tasks. 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.
