    Restart both your speakers and the audio source

    Re-pair the audio source with your speaker

    If you’re streaming audio content from the internet, the issue could be with the internet connection and not your speaker

  • Charging the Speaker When Wet
    You will need to dry the charging port completely before plugging in power for charging.
     
  • Does my Speaker have Speakerphone/Voice Assistant Functionality?
    This product does not feature speakerphone or voice assistant functionality as it does not have a microphone.
  • How to avoid Bluetooth Interference or Interruptions
    • Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.

    • Try to shutdown other products that have Bluetooth, but are not being used. They are often the reason for interference even though they are not being used.

    • Do not stand too close to your Wi-Fi router since a Wi-Fi signal is stronger and in many cases will "overlap" the connection.

    • Be aware of walls around you. Concrete and brick walls will often interrupt the signal, as it cannot pass through such thick walls.

    • Bluetooth signals cannot travel through water, which includes the human body. Make sure with wireless headphones to keep your source device and the receiver on the same side of your body.

    • Open spaces such as parks can cause issues for your devices, as open air is "bad" for any Bluetooth signal if it cannot reflect from objects around you.
  • How to reset Boombox
    In power ON mode press and hold the "Volume +" and "Play" buttons at the same time for more than 3 seconds -> Unit will power Off by itself. Now the unit is reset to factory default.
  • IP67 Information
    This product is rated IP67, which is different from IPX7. IP67 protects the product from submersion in 1 meter (3.3 feet) of water for up to 30 minutes. It is also resistant against dust. Dust accumulation around electronics can lead to hardware failure, so the IP67 rating is an extremely beneficial addition to this product. 
  • PartyBoost Stereo Pair Proximity Issues With Other Speakers

    If you create a Stereo Pair using the JBL Portable App and you come within range of additional PartyBoost compatible speakers while they are ON, the app will find these speakers. This will break the stereo pair and create a mono PartyBoost group that includes all active speakers that are in proximity. This only happens when the JBL Portable App is actively running on the source device, including when it is running in the background, and when these other speakers are ON. To avoid this scenario, make sure the app is completely closed, without running in the background before coming near any additional PartyBoost speakers that happen to be ON.


    NOTE: The Portable App does not need to be running in order to enjoy Stereo sound from two speakers

  • PartyBoost support on the JBL Connect and JBL Connect+

    The new PartyBoost does not support the previous Connect and Connect+ features. For example: You will not be able to successfully connect the new PartyBoost enabled Flip 5 with a Connect+ enabled speaker like the Pulse 3 or Flip 4. You will not be able to connect the Boombox 2 to the original Boombox speaker.

  • Setting up Multiple Partyboost Speakers in a Group
    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
