Update Without The App - Ultimate Ears BOOM 3 Faq

Update without the app

While it is quickest and easiest to update over-the-air with the app for your
ULTIMATE EARS speaker, if you can't update using the app or you simply prefer to
use an old-school desktop updater, we've still got you covered. Click on the Mac
or Windows download link below to download the update utility. After you
download the app, run it and follow the on-screen instructions. You'll need to
connect your ULTIMATE EARS BOOM 3 to your computer to complete the update.
REQUIREMENTS: This update supports Windows 7 and above, Mac OS X (10.8.x) and above.
