3M Peltor Optime 101 H7P3E Cap-Mounted Earmuffs (SNR 30 dB)

The 3M Peltor Optime 101 H7P3E are cap-mounted earmuffs delivering a high SNR of 30 dB. They clip onto a hard hat’s accessory slots so workers get strong head and hearing protection in one system, ideal for high-noise sites where helmets are required.

Product overview

The Optime 101 H7P3E is the cap-mounted version of 3M’s high-attenuation Optime 101 earmuff. Because it attaches to compatible safety helmets via 30 mm slot adapters, it removes the need for a separate headband and stows up out of the way in quieter areas. Deep cups and soft cushions keep the muffs comfortable through long shifts.
