    3. Turn on the second speaker that you want to connect in Partyboost mode.

    7. Allow the app to identify both speakers.
    8. Click the Partyboost button, you will see the option for Party or Stereo, select Stereo.

    Please note: Stereo Mode can only be enabled when 2 of the same speaker model are used.
    For example, you will not be able to achieve Stereo Mode with a Flip 5 and Flip 6, only Party Mode.
    Also, it is not possible to pair speaker models with Connect and Connect+ together, or pair to speaker models with Partyboost.

  • When I connect my JBL speaker with a computer (PC/Laptop/Apple Mac/Nintendo Switch), can I use the PartyBoost feature?
    The PartyBoost feature is not available when your JBL speaker is connected to a computer via Bluetooth. This is a technical limitation. When connected to a computer, the computer is acting as the primary device. Therefore, the JBL speaker does not have control of re-transmitting the Bluetooth signal to other JBL speakers.

    NOTE: Speakers effected by this are the JBL Flip 5, JBL Flip 6, JBL Charge 5, JBL Pulse 4, JBL Xtreme 3, and JBL Boombox 2, as well as all future products featuring the PartyBoost feature.
