I've just found this headset to be too much for the A320. I only used it a little bit.
The microphone can be connected to either earcup for convenience. Measures 8.4"h x 6.3"w x 3.2"d. Includes A20 dual plug (GA or Boeing normal plugs) Aviation Headset, in-line clothing clip, control module, aux-in cable adapter, carrying case.
