3M In-Ear Electronic Ear Plugs, Ear Plugs Dependent Noise Reduction Rating NRR, Dielectric No, 1 PR

Communication headsets and earpieces combine hearing protection with the ability to connect to a radio network for hands-free communication between compatible devices. They also prevent those nearby from overhearing incoming communications to maintain privacy and avoid distraction. Listen-only devices allow the user to receive voice and audio messages while two-way devices allow the user to give and receive messages. These headsets and earpieces are ideal for maintaining communication between different areas of a workplace and coordinating teamwork at construction sites, emergency scenes, refineries, airports, and other loud settings.

Listen-only earpieces connect to an external radio, walkie-talkie, or personal audio device to give users the ability to receive messages or listen to music or other audio. When used with a walkie-talkie, they also allow users to transmit messages. They have ear plugs that fit into the ear canal to form a seal against outside noise and a cord for plugging into a compatible device. Compared to ear muffs, ear plugs are more portable and more comfortable to wear over a longer time period and when working in hot or humid areas. They also won't get in the way of hard hats, faceshields, or eyewear.
