The functional headset with overhead headband and Vox function allows you to communicate efficiently. Thanks to the mono earphone, you always stay in touch with your environment, even during conversations. The Vox function gives you even more freedom when working with your radio as it allows you to answer without pressing a button. This voice-controlled function is activated as soon as you speak into the microphone. Speaking activates the transmitter and transmits the spoken message to the person you are talking to.
