Extend the length of your headset or helmet cables and adjust the volume with an inline knob.
Now each person in the vehicle can adjust their headset or helmet kit volume independently. Are you a moto rider? Adjust the volume without having to reach for your tucked away phone or radio.
The volume knob attenuates the incoming volume and does not increase the volume. If users need more volume, turn the volume up on the device and then adjust personal volume settings with the inline knob on the extension cable.
