How to Use LabSync With JLab Party Speakers

LabSync links compatible JLab Party speakers (GO Party, Pop Party, JBuds Party, and Epic Party) so they play in sync. One speaker uses Cast mode while connected to your phone or other Bluetooth source; additional speakers use Receive mode and follow the Cast speaker.

You do not need the JLab app to use LabSync. Enter Cast or Receive mode with the speaker button shortcuts below.

The JLab app on iOS and Android is optional. Use it to set left, right, or stereo channels, sync volume and lighting, and adjust settings before you start. Step-by-step app guides are at the bottom of this page.
