Intermittent audio from product
If the sound played from your product cuts in and out, plays inconsistently or is choppy-sounding, try the following:
Check for and install any available product updates.
On a computer, visit btu.bose.com and follow the instructions to ensure your product has the latest features and enhancements. See Updating the software or firmware of your product.
Check the cellular reception of your phone.
A weak connection to the cell service could cause poor audio quality while on a call. Try the call again when the reception improves.
Check if the issue occurs only with the control module switch in the MUTE / top position.
Set the control module's mode switch to the bottom position for OFF (Intercom Only) mode. If there is no issue in Intercom Only mode, but the issue persists using MUTE (Intercom Prioritized) mode, there could be sound getting into the microphone.
In MUTE mode, any audio received from the intercom always takes priority. For example, if the microphone brushes up against something or is breathed into, that sound comes from the intercom and will take priority causing any non-intercom audio to mute. Adjust the squelch setting or reposition the mic/cable to avoid unwanted noise entering the mic.

Determine if the issue occurs with a connected auxiliary device.
Put the audio selector switch on the headset control module in either the middle or top position. (Be sure it is not in the down / Intercom Only position.) Then, disconnect the headset from the panel and connect an audio device to the 3.5 mm aux input on the headset control module. If you have a headset with Bluetooth®, you can connect a Bluetooth device instead: If the issue still occurs with the aux device, there is an issue with the headset; if the issue is not present with the aux device, the issue is related to the panel settings or connections.
Replace the cables used to connect your product
Try replacing the cables that connect your product. If no issue is heard with new cables, the first set of cables is the issue.
Try connecting a different Bluetooth® device.
If your Bose product can connect to another device, Bluetooth functionality is working. In cases like this, the issue could be with the first device or its settings.
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.
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.
