Why won't my JBL speakers connect to each other?
If your JBL speaker won't connect or keeps disconnecting, chances are your device is too far away, or another device is interfering with the connection. Ensure the speaker has sufficient charge, that both devices have Bluetooth enabled, and close enough to pair. If all else fails, reset the speaker.
How do you connect JBL speakers together?
To connect multiple JBL speakers that are 'Connect capable,' simply press the 'Connect' button after pairing the speakers with your audio source. On your other JBL Bluetooth speaker, press its 'Connect' button. This should signal all the other Bluetooth speakers that they have been linked for simultaneous playing.
