Ultimate Ears today updated its iOS and Android apps with a feature called 'Party Up' that lets users connect 'more than 50' of its Bluetooth speakers at once (via TechCrunch). When synced together, every speaker can be simultaneously controlled from a single mobile device, with the music selection and volume synced together across every speaker. Additionally, the company's UE Boom 2 speaker is gaining Siri integration with today's update, making it 'quicker, easier, and more convenient than ever to keep your party going.' After updating the app, users can find the new setting by swiping right-to-left on the home screen. In this new Party Up section of the app, guest speakers will appear at the bottom of the screen, called the drawer, and all users have to do is drag and drop each speaker they want to sync up into the middle of the screen. Similarly, to remove a speaker from the party, drag and drop it back into the drawer.PartyUp is an exclusive UE App feature that lets you wirelessly connect 50+ speakers and take your music where no other portable bluetooth speaker can go.
