Noise cancellation is not working | Bose Aviation Headset X

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.

In non-pressurized aircrafts, the effectiveness of noise-cancellation decreases as the alititude increases. The headset might also produce a whining sound in these situations. For info on maximum altitude for full noise cancellation, refer to the headset specifications.

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.

1. Disconnect the down cable where it attaches to the panel
2. Inspect the connections for damage or debris and remove any debris that is found. If there is damage to any the connections, they may need to be replaced
3. Firmly reconnect the down cable to the panel

Note: Typically, a clicking or popping sound is heard when taking the plug in and out of the jack; this noise confirms the headset is receiving audio.

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.

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

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