Update: cant switch devices with out this app, connection failure when phone app is installed on is connected. Chatging case required. A pointless headeche. Then have to turn off bluetooth so airbuds in case dont steal your phones audio. Its not music its only Bose device control. Still doesn't give you the option to turn off the air buds. So if you think you are going to use you phone. Better know how to get to your buds or turn off bluetooth.
