3M Peltor Optime 98 H9P3E Cap-Mounted Earmuffs

The 3M Peltor Optime 98 H9P3E are cap-mounted earmuffs that clip onto a hard hat’s accessory slots, protecting hearing without a separate headband. Built for moderate-to-high noise, they let workers combine head and hearing protection in one comfortable system on the worksite.

Product overview

The Optime 98 H9P3E version attaches to compatible safety helmets via standard 30 mm slot adapters. Because the muffs mount on the cap, they free the head of a separate band and stow up out of the way when not needed. Twin-cup cushions and a balanced clamp give comfortable, consistent attenuation through the shift.
