3M 7100088423 Listen-only Earmuffs Black

Product Description

The 3M 7100088423 is a listen-only earmuff designed for single-way audio communication in occupational and industrial environments. Unlike standard passive hearing protectors, listen-only earmuffs allow the wearer to receive audio signals, announcements, or radio communications through built-in speakers while maintaining ear protection. The black cup design is suited for professional field use. Licensed trades and safety-conscious contractors working in high-noise environments rely on this type of equipment to stay connected to site communications without removing their hearing protection.

This earmuff is appropriate for use in commercial, industrial, and infrastructure job sites where workers need to monitor radio or intercom audio while exposed to elevated ambient noise levels. It is commonly used by electricians, HVAC technicians, pipefitters, and other skilled tradespeople operating near loud equipment. The unit ships as a single piece and is packaged individually.

Installation Notes

Follow applicable OSHA hearing conservation program requirements when issuing personal protective equipment on job sites. Inspect cups and seals regularly for wear that could reduce attenuation performance.
