Description

From the seller
The AUX port allows a compatible audio device to be connected with a standard 3.5 mm auxiliary cable, making it possible to listen to audio while wearing the earmuffs. Their electronic circuitry amplifies quieter ambient sounds such as conversation while automatically limiting loud impulse noises, including gunfire, to help protect hearing.
