How do I know I have the lastest firmware?

To check your speaker’s firmware version, go to the Speaker Settings section of the Ultimate Ears app (the gear icon on the top right of the app home screen). Scroll down to the bottom of the page. The app will display the current firmware version and will automatically check if there is newer firmware available. If the auto-update setting has been disabled or if you’re just curious, you can always tap the “Check for Updates” button to manually check for software updates.
