3M Over-the-Head Electronic Ear Muffs, 26 dB Noise Reduction Rating NRR, Dielectric No, Black

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. They have ear muffs that fit over the ears to insulate against outside noise. 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.
