FAQs & How-Tos

6 results
  • You will need to dry the charging port completely before plugging in power for charging.
     
  • You cannot download the JBL Portable App on a PC. This app is only available on mobile devices.
  • Your JBL speaker is waterproof with IPX7 rating. (IPX7 means it can survive immersion in 1 meter/3.3 feet for up to 30 minutes.) To maintain the looks and functions of your speaker, please make sure to rinse it with fresh water after using it at a swimming pool or the ocean, then dry off all covers and areas where water can gather. The standard for waterproofing is for tap water. Chemicals and salt in your pool or the ocean can damage the waterproof seals or harm the surface finish over time if not rinsed off after use.
  • 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. PartyBoostButtonsGroup.png
  • 1. Turn on both speakers.
    2. Connect your device to one of the two speakers via Bluetooth.

    3. Start streaming music to that speaker (for best results play music on this speaker for more than 20 seconds before proceeding with the next steps).
    4. Open the JBL Portable app.
    5. Allow the app to detect the single speaker playing music.
    6. Once detected, press the Connect/Partyboost button on both speakers.

    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.

  • 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.
