Crackling sound in one earcup | Bose Aviation Headset X

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.

Be sure the headset is being worn properly.

Due to the angle of the earcups, proper left and right earcup placement is essential for the headset to fit around both ears. The headset's performance can be greatly reduced if the earcup fitment around the ears is poor. For more information, see Wearing and adjusting your product.

Raise the volume level on the Down Cable.

The issue may be caused by having the volume setting too low. Increase the volume gradually to the highest setting.

Check if the noise is affected by the volume control on the aircraft panel volume control.

Without adjusting your headset volume, turn up or down the volume control on the aircraft panel. If the noise level changes as well, the noise is related to the signal being received from the panel.

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).

If you have ever unplugged the microphone cable from the headset, disconnect it again and check for debris or damage at the connectors.

Make sure the connectors on the cable and at the headset are both free of debris (dirt, lint, dust, etc.) or damage, which could prevent a proper connection. For more info, see Attaching or moving the boom microphone on the headset.

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.
