Elvex Com-655 Level Dependent Earmuff

Designed to improve close range communications in noisy environments. Microphones on the outside of this earmuff amplify weak sounds while the gain limiter suppresses sounds exceeding 82 dB. Frequencies below 400 Hz and above 4,000 Hz are not processed, so the speech-to-noise ratio is improved in continuous noise environments. An audio jack allows for connection to a radio for listen-only capability so that you can hear the auxiliary device and the Com-655. After four hours of continuous use, the auto off feature turns off the headset to conserve battery power.
