QuietComfort Earbuds II Update process

1. When an update is available, the Bose app automatically downloads it.
   
2. Once downloaded, the app transfers the update to your earbuds, which can take up to 45 minutes
   Tip: The earbuds must be connected to the app for this to happen. The app can be open or minimized, but closing the app stops the transfer. Additionally, the earbuds must remain in your ears and within Bluetooth® range to stay connected and download the update.
3. Tap "Install Update."
   
   
4. Tap "Update Now" and follow app instructions to complete the update.
   
   
5. When the update is complete, the status light on the charging case goes out.
6. Take the earbuds out of the case and place in your ears. You should hear the connection "Vroom" tone. If not:
   1. Keep the earbuds in your ears and wait 2 minutes for the earbuds to reboot.
   2. If you still do not get the connection tone, place the earbuds in the case, close the lid for 10 seconds. Remove the earbuds from the case, place in your ears and try again.
