About Hearing Protection

Earmuffs and earplugs are rated by the Noise Reduction Rating (NRR) guidelines, which are enforced by OSHA.

Earmuffs should be worn with the specified fit to offer proper protection and noise reduction.

You can wear Style C earmuffs over the head, behind the head, and under the chin.

Wired Headset Radios

Over Head Headset

Behind Head Headset

Connect two headsets with an audio cable to transmit sound—your voice powers the radio’s microphone.

Behind-head style can be worn under a hard hat.

Use a wall plate jack to create a fixed system between locations. Plug a radio into the jack and start talking. Any number of jacks may be wired together.

Use a clip adapter to temporarily connect a radio to two wires rather than using a fixed wall plate jack system.

Headsets with Microphone

Over Head (Single Output)

Over Head (Dual Output)

Make hands-free calls from your computer, laptop, smartphone, or other device. The headphones and microphone cancel background noise, so you and the person on the other line hear each other clearly without distractions. Bend the microphone’s arm closer to or away from your mouth to improve the clarity of your voice. These headsets have a call controller on their cord with buttons to quickly answer and end calls, adjust the volume, and mute yourself.

Headsets with single sound output cover just one ear, so you can hear people in the room on your end. They’re useful for relaying messages and instructions.
