Clicking sound in one earcup

If your headphones produce an unexpected ticking, clicking or popping noise from one side, try the following:

Determine if any recent changes have been made to the headset or aircraft.

If any changes or modifications have been made to either the headset or the aircraft, look into whether or not those changes could have unexpectedly caused this issue.

Connect the headset to a different panel jack or, if possible, to another aircraft.

Non-TSO equipment, worn jacks/loose connections, or incorrectly wired jacks (i.e. reversed stereo or mic / ground wires) in the aircraft can cause issues. If available, try connecting the headset to another jack in the aircraft or to jacks in a separate aircraft. If the headset works fine when connected elsewhere, the panel jack or wiring to the jack is the issue.

Determine if the issue occurs when your headset is powered off.

Your headset works in passive mode (powered off with no noise cancellation). If the issue still occurs while the headset is powered off, the issue is related to signal coming being received by the headset from the aircraft panel (i.e. the connections, wiring, or interference).

Determine if the issue occurs when the mic is in use.

If the issue only occurs when speaking through the microphone, the Down Cable may be defective. Follow the link for more information on how to service your product. Depending on your product and region, you will be provided a contact number or the ability to setup service online.

Check for interference that could be causing unwanted noise.

While the noise is present, slowly move or turn your head away from sources of interference — like window heat, antennae, power cords, etc. If the noise is more noticeable as you get closer to a device or area in the aircraft, it is related to interference from that device or area. In some cases, repositioning even just a few inches can help. (Tip: If necessary, the headset can be used in passive mode — powered off with no noise cancellation — to avoid interference).

Determine if the tone of the noise changes when the avionics panel is touched.

If the tone changes when the avionics panel or any other area of the plane is touched, there may be a grounding issue with the aircraft or the intercom connections and associated wiring.

Plug in a different headset.

If available, connect a different headset to the aircraft to determine if the issue is related to the aircraft panel or its settings.

For 6-pin aircraft-powered installed connections, check the condition of the plug on the headset and the jack on the aircraft.

Check for any debris in the connector on the aircraft and check if any of the six pins are missing inside the headset plug.

Note: If the aircraft has a jack for an older model Bose AHX headset that was wired to provide mono audio to the right earcup, the jack will need to be rewired since the electronics in the newer A20 cable differ.
