The MG-20H Music Adapter for Helicopter / Military Headsets allows you to interface your portable music device with a Helicopter or Military Headset.
This will allow music to be heard only through the individual Headset it is connected to. It will not go into the panel for all of the passengers to hear.
This adapter has no additional amplification, it relies on the volume of your music source. The result may not be loud enough in a Helicopter.
