  • My device is waterproof, but what about salt water or chlorine water?

    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.

  • Does this speaker have an Aux Input?

    This speaker does not have an Aux Input, so no analog connection is possible.
  • 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.
  • 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

    Product information
  • Pulse 4: Light Show has Low Intensity

    The intensity of the light show is dependent on the amount of audio signal being sent into the unit.

    If you are experiencing a light show that doesn't move around very much, it is likely that you are not using a feature on your phone called Bluetooth Absolute Volume*. This means that the volume of your phone/tablet/device is controlled independently from the volume of the speaker.

    So, if you have the Pulse 4 set to maximum volume or close to it, but the volume on your device is set at a low level, the light show will show little to no effect. All you have to do is reverse it. Turn up the volume on the device to the maximum and set the Pulse 4 to the desired volume. This will send the correct level to the speaker and the light show will show plenty of effect. This also benefits the sonic quality as well. Therefore, we recommend always having the volume on your device turned up to a high level and then adjusting the volume level on the speaker itself. This way you'll be able to enjoy the light show while also getting good audio quality. Or, if possible, setup your device for Bluetooth Absolute Volume*.

    *BLUETOOTH ABSOLUTE VOLUME: Most phones/tablets/devices now use Bluetooth Absolute Volume (a.k.a. volume sync) by default. This is a feature that synchronizes the volumes of the device and the speaker, and allows the speaker volume to be controlled by changing the volume on either the device or the speaker. The volume being sent from the device is fixed at full volume.


  • What are the differences between Partyboost and Connect+

    Our newest products, such has JBL Pulse 4 and JBL Flip 5, feature a new technology called Partyboost .

    Partyboost technology
    • Improved Bluetooth connection between speakers.
    • A more powerful Bluetooth transmitter means that the speakers can be farther apart.
    • Partyboost can only connect to other Partyboost speakers.
    All newer Portable products from JBL will have Partyboost integrated.
    Unfortunately, this feature is not backwards compatible with  previous models that have JBL Connect or Connect+.
