FAQs & How-Tos
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.
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
• 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.
Software updates for your speaker can be done using the JBL Portable app.
Download it from the Apple App store and Google Play store.
If there is an available update, look for the small red dot above the gear icon and follow the download instructions (see image below).
If you have an issue with your device it is always worth checking if there is a Software update available and performing the installation if there is.
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.
The driver (software) should support the following Bluetooth protocols, to be able to play music/sound from your Computer/PC/Laptop:
• A2DP (Advanced Audio Distribution Profile) driver for your Computer/PC/Headphones to transfer music.
• AVRCP (Audio/Video Remote Control Profile) driver to send skip/forward/pause/play music to your device
Always get the latest driver version available for your Computer/PC/Laptop.
To download the correct driver (software), visit the manufacturer's website of your Computer/PC/Laptop. They usually have a "Support/Download" section where you can find the correct driver. Otherwise, we advise you to contact their support.

Move the audio source closer to the speakers
Move the speakers closer to each other
Make sure the streaming speaker (host) only connects to one audio source, disconnect the Bluetooth connection between the streaming speaker (host) and other audio source
Make sure the audio source only connects with one streaming speaker (host), disconnect the Bluetooth connection between the audio source and other speakers
Restart both your speakers and the audio source
Make sure speakers are away from other sources of wireless signal – you could be experiencing interference
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

If there are drop out or connection issues when using PartyBoost or Connect+, it could be one of three things.
1. Units are too far apart (move units closer together)
2. Interference from other 2.4gHz wireless units in the area.
3. Unit is no longer working as designed
Here are some steps to isolate the issue:
Try taking the units out of the house and test it outside with no interference to see if you still experience connectivity issues. If you still experience connectivity issues, please try steps below:
Whatever unit drops off, remove that from the chain. Test the rest of the speakers and keep doing it until you find the speaker that is causing the drop outs. If all speakers begin to drop off, please try a different order and repeat. Repeat this process with each unit being the “main speaker”.
Make sure to turn off all WiFi/RF devices. (Router, laptop, baby monitor, Nest cams, IP cams, WiFi switches, WiFi outlets, WiFi lights, cordless phones, etc.)
You should be able to identify the issue/speaker by following these 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.
Portable speakers with an Aux-in port, such as the Xtreme 3 and Boombox 3 - if connected through an Aux cable, should have less issues compared to using Bluetooth, however there can be issues with audio/video synchronization if used for this purpose.
Support for Bluetooth connectivity between a TV and speaker depends on a number of different factors such as Bluetooth & A2DP versions and Audio Codecs used by each device. This can vary based on the brand, model and age of the devices, however we cannot confirm if any specific combination of TV and speaker will work without issues such as latency or lip sync delay.
This unit is IPX7 rated, which means that you can submerge the unit in water as deep as 3 feet (1 meter) for up to 30 minutes.
