QuietComfort Earbuds II are engineered to get better with time. Our intent is to add new features via over-the-air software updates. In order to receive these updates, it is important to download the Bose Music app. The first time you connect your QuietComfort Earbuds II to the app after a software update becomes available, you’ll be notified that the update is downloading. Putting the buds back into the case will complete the installation.
