1) Ensure that the buds are connected via Bluetooth and the Noise Audio App, and that they have over 50% charge.

2) Open the Noise Audio App, go to Settings, and select the Firmware Update option.

3) If an update is available, tap to update; the process may take a few minutes—do not exit or refresh the page during the update.

Note: The V29 update is mandatory and is prompted automatically on the first app connection (refer to “Mandatory Firmware Update (V29)”).
