Attaching or moving the boom microphone on the headset

The microphone boom and attached cable can be mounted to either the left or the right earcup, depending on your preference. Learn how to disconnect and reconnect the microphone assembly to replace it or swap sides on your headset.

To reattach or relocate the boom microphone:

  1. On the microphone connector at the earcup, loosen the two screws using a Phillips screwdriver, then pull the connector from the earcup
  2. On the terminal cover at the other earcup, loosen the two screws, then pull the cover from the earcup
  3. Align the microphone connector to the desired earcup, then tighten the screws to secure it in place
  4. Align the terminal cover to the opposite earcup, then tighten the screws to secure it in place
  5. Test the headset before flight.
