1. Connect the first Partyboost speaker with your phone and keep music playing (for best results play music on this speaker for more than 20 seconds before proceeding with the next steps).

2. Press the Partyboost button on the first speaker.
3. Turn on the second speaker that you want to connect in Partyboost mode.
4. Now press the Partyboost button on the second speaker.
5. After a few seconds, both Partyboost speakers should connect and play together.
It can take a few seconds after music is started before sound will be heard from both speakers.
This is also the process for connecting more than two speakers in Party mode, simply turn on the other compatible speakers and press the Partyboost buttons.
