With Double Up, you can connect your WONDERBOOM PLAY with another WONDERBOOM PLAY for a bigger sound. To Double Up, long press the play/pause button for 3 seconds on one speaker, then long press the play/pause button on the other speaker. Once pairing succeeds, you will hear a confirmation tone from both speakers, and music will now play from both speakers.

Long press the play/pause button again after pairing to toggle between mono mode (louder volume) and two-channel stereo mode.

Long press the power button on either speaker to leave Double Up mode.
