3M 7100099585 Communications Headset 27 Nrr

Product Description

The 3M 7100099585 is a communications headset designed to deliver both hearing protection and two-way audio capability in a single unit. It carries a Noise Reduction Rating (NRR) of 27, making it suitable for moderate-to-high noise environments where workers still need to maintain clear voice communication. The three-position band design allows the headset to be worn over the head, behind the neck, or under the chin, accommodating helmets, hard hats, and other PPE configurations. Licensed professionals in industrial, construction, and facility maintenance trades rely on this type of unit to stay in contact with team members without removing their hearing protection.

This headset is appropriate for environments where ambient noise levels require hearing protection under OSHA guidelines while simultaneous radio or intercom communication is necessary. Typical applications include construction sites, manufacturing floors, utility work, and facilities maintenance. The flexible band positioning makes it well-suited for workers who rotate between head-worn PPE throughout a shift. It ships as a single unit.

Installation Notes

This headset is worn PPE and does not require mechanical installation. Fitting should follow the manufacturer guidelines to ensure a proper acoustic seal and adequate noise attenuation. Workers should verify compatibility with their communication system or radio before deployment. Inspect the headset regularly for wear, damage, or degraded seals that could reduce NRR performance.
