Description
The 3M™ PELTOR™ Optime™ 101 Earmuffs – H7B provide reliable, high-attenuation hearing protection in a behind-the-head configuration, ideal for users wearing hard hats, bump caps, or other headgear that might interfere with traditional over-the-head styles. These earmuffs offer a Noise Reduction Rating (NRR) of 26 dB and are CSA Class A certified, delivering effective attenuation across high and low frequencies. Designed for comfort and performance, the earcups apply even pressure for a snug but low-pressure fit, with replaceable cushions and foam liners available to extend product life.

Behind-the-Head Design : Ideal for use with hard hats or helmets that would interfere with over-the-head earmuffs.
Consistent, Comfortable Fit : Earcups provide uniform pressure for an effective seal and comfortable all-day wear.
Replaceable Hygiene Components : Compatible with 3M™ PELTOR™ Hygiene Kit HY7 for ear cushion and liner replacement.
E-A-Rfit™ Dual-Ear Validation Compatible : Fit can be verified with 3M™ E-A-Rfit™ system to ensure optimal protection.
