Elvex COM-655 Electronic Non-Foldable Ear Muffs with Impulse Filter & 3.5mm Audio Input Jack, 25 dB NRR, Weight: 12.8 oz. by Elvex


Description

This Item Includes: Two 1.5 Volt AAA Batteries;The communications features allow you to have close range communications in select continuous noise environments. The microphones on the outside of the ear muffs listen to the environment and can amplify weak sounds, and the gain limiter suppresses sounds exceeding 82 dB.;Frequencies below 400 Hz and above 4,000 Hz are not processed and therefore the speech to noise ratio can be improved in many continuous noise environments.;An impulse (or impact) filter electronically eliminates impulse sounds by closing down the circuitry in four milliseconds, and opening the circuitry againin about 1/4 second (in order to prevent echo effect). The gun shots are eliminated, but the shooting instructor can still be heard.;An audio jack (3.5 mm jack) for connection of MP3 players and radios is standard. This jack willprovide listen-only capability (not two way communications). You can hear both the auxiliary device and Com-655.
