3NZF3 EAR MUFFS HARD HAT MOUNTED NRR 24DB

Ear Muffs: Hard Hat-Mounted Earmuff, Passive, 24 dB NRR, Polyurethane/PVC/Foam. 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.
