Poor sound quality from product | 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.

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.

Try connecting a different audio device.

If available, connect another audio device using the same cables and connections to determine if the issue is related to the first device or its settings.

Replace worn ear cushions.

The issue may be caused by the lack of a proper seal by the ear cushions around the ear. Also check to be sure the cushions are securely attached to the earcup. Replacing worn ear cushions will aid in comfort, the performance of the active noise reduction and battery life

Be sure the headset scrims are clean and free of debris.

Check for blockages in the scrim (the cloth grille inside earcup opening). Excessive debris can result in low audio or poor sound quality.

Check if the issue only occurrs during certain events.

It's possible unexpected noise might occur during certain events, like takeoff and landing. This is typically due to other electronics in the aircraft interfering with the electronics in the headset. While this isn't common, interference can occur with between electronics. If possible, determine the source of interference and if the source can be turned off, relocated or shielded from 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.

Disconnect all other headsets connected to the aircraft.

Unplug any other headsets connected to the aircraft intercom. If the issue goes away, it is related to another headset. Reconnect the headsets one-by-one to determine which, then check the settings for that headset.
