Poor sound quality from product

Remove the batteries from the control module to view the headset option switches: Set the INTERCOM switch to ST (right position) or MONO (left position). When finished, reinstall the batteries.

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.

Set the device volume to 90–100% to send a strong signal to your product. Then, use your product to adjust the volume level.

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.

These headphones are designed specifically for use with StayHear+ eartips. Use of any other eartips, including original StayHear tips, will result in low audio, poor sound quality and/or reduced noise cancellation.

Your StayHear+ Tips should look like this:

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.

The connectors at the end of the headset cable might have debris or corrosion on them. Apply a small amount of isopropyl alcohol to a cloth, wipe the metal connectors, then dry them with a clean cloth. Once cleaned and dried, connect the headset and try again.

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.

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.

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.

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