When you Double Up, you connect two ULTIMATE EARS BOOMs together for bigger sound. The easiest way to set this up is to use the Double Up option of the ULTIMATE EARS BOOM app. Once your ULTIMATE EARS BOOMs are Doubled Up you will be able to play to both at the same time from one phone or tablet.
After the two ULTIMATE EARS 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 ULTIMATE EARS BOOM app.
In the Double Up section of the app, you can choose how you would like the speakers to behave. There are two options:
- STEREO: In this mode, the two speakers play as a stereo pair, with one speaker dedicated to the left channel and one speaker dedicated to the right. You can even define which of the two ULTIMATE EARS BOOMs should be left and which should be right.
- DOUBLE: In this mode, the two speakers play identical streams.
You can also Double Up two ULTIMATE EARS BOOMs without the app:
- Simultaneously press the Bluetooth and + buttons on the speaker that is playing music.
- Then press the Bluetooth button twice on the speaker that you want to add.
