3m Electronic Ear Muffs Includes (2) AA Batteries HRXS221A-NA

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 headsets 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 muffs that fit over the ears to insulate against outside noise and a cord for plugging into a compatible device. Compared to ear plugs, ear muffs provide a longer life and a more consistent fit for reaching their optimal noise reduction rating (NRR). They're also more visible than ear plugs for confirming that workers are complying with hearing safety rules. Headset, 26dB, Headband
