Thanks Oldpilot, ?I have a regualr Bose noise canceling headset and have added the micrphone piece to it. The cable needs to have a 2.5 or 3.5 mm stereo plug on one end and aviation sized plug ont the other. For my Garmin Virb I have something similar to record the in cockpit audio.
it is just a matter of finding the right cable.
