When you Double Up, you connect two UE BOOMs together for bigger sound. The easiest way to set this up is to use the Double Up option of the UE BOOM app. Once your UE BOOMs are Doubled Up you will be able to play to both at the same time from one phone or tablet.
After the two UE BOOMs have been synced together for the first time, they will then automatically Double Up the next time they are both powered on together. To turn this feature off, so that the speakers won’t automatically sync with each other the next time they are both are powered on, switch the ‘Double Up lock’ setting to ‘OFF’ in the Settings section of the UE BOOM app.
