Periodic updates will available for your headphones. We recommend downloading the Bose Connect app to keep your headphones up to date.
Updating your headphones in the Bose Connect app
The Bose Connect app will check for updates upon opening and connecting to your headphones. The download icon will appear if an update is available. The update will begin automatically and start downloading to your device. This step can take up to 45 minutes and progress is indicated by the circle in the download icon. In this stage, you can still use your headphones normally while the update gets ready in the background.
Once the update is ready, "UPDATE" will appear in the app. Tap it to update your headphones.
This process should take a few minutes. Do not turn off your headphones during this process.
Updating your headphones manually
You can also update your headphones by going to btu.Bose.com and following the on-screen instructions. This method may be faster; however, you will need a computer and a micro-USB cable.
