FAQs & How-Tos

How can I check the software version on my Flip3, Flip4 or Xtreme??
By pressing Volume - & JBL Connect button for 3 seconds. A voice will tell you the current software version.
JBL Xtreme: iOS 14+ Compatibility
The JBL Xtreme will not be supported by the JBL Portable app while using Apple devices with iOS 14 or later versions due to incompatibility. 
You can continue to use the speaker through Bluetooth or Aux connection and manual pairing, but cannot stereo pair with another Xtreme through the JBL Portable App.  
There is no plan to release a new Firmware currently as the JBL Xtreme has been discontinued.

If you still wish to use JBL Xtreme with the JBL Portable app, please connect it with Apple devices with iOS 13 or below, or connect it with Android devices.
Upgrading the software on your PartyBoost or Connect+ Speaker

If there is an available update, look for the small red dot above the gear icon and follow the download instructions (see image below).

Can I place my Xtreme in the bathroom, where it is humid, and it may be splashed with water?
Yes, steam and drops of water in a bathroom are fine.
Can i connect 3 or more speakers together with JBL Connect?
No, for now it is only possible to connect two speakers together using the JBL connect feature. Newer JBL products feature JBL Connect+, which allows you to connect > 100 devices simultaneously, these however are not compatible with older JBL products featuring JBL Connect
After I updated my computer to Windows 8/10, I am no longer able to establish a Bluetooth connection with my speaker to play music. How can I correct the problem?
This is because most Windows do not support A2DP stereo audio streaming via Bluetooth, the standard for music-listening through Bluetooth. The system will support keyboards, mice, printers etc. via Bluetooth, but not audio. It is necessary to download the proper drivers, either from the computer manufacturer, the software manufacturer or the manufacturer of the Bluetooth chip in the computer. Help to do this must be sought with the companies that supply one or more of these computer features.
Can I use my Xtreme outside in rainy weather?
Yes, this is no problem.
How can I see that the device is fully charged?
When the Xtreme is ON, the row of 5 diodes at the bottom of the front will light up in turn, with the top flashing LED showing how far charging has progressed. When full charge has been reached, all diodes light constantly. In some cases, the fifth diode keeps on blinking, but does not light up constantly, no matter how long charging continues. Sometimes it will show constant light after charging has been stopped. This is normal, caused by tolerances in the circuits, and is no cause for alarm. The battery is charged to the same level. If the Xtreme is OFF, no diodes will light when full charge has been reached.
What can I do with the Connect app?
It is possible to rename the Bluetooth name of the primary connected device and set the Party or Stereo mode. If a firmware upgrade is available for any Connect, Connect+, or Partyboost compatible speaker, this can be installed through the JBL Portable app. Only identical products can be set to stereo mode. Please note that, even though you can pair a Boost TV with JBL Connect, you cannot control this from the JBL Connect App
When using JBL Connect, how far can i take the second speaker with me?
JBL Connect feature is using Bluetooth technology, so it is hard to say how far you can walk away. Depending on what other signals you have at your place that could interupt and wall material between 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.

Information on different firmware versions on same products and models

My Xtreme got dirty after a day on the beach. Can I rinse it under the faucet or shower?
Yes, rinse it under a faucet or under the shower, but not under full water pressure.
Is the device still splash-proof if the zipper over the connection panel is open?
No, only if the zipper is closed.

How can I connect two JBL Connect compatible speakers together?
Please press JBL Connect buttons on both speakers to connect.
Does the Xtreme has the same sound with and without AC power connected?
If you are playing on battery only, you may experience slightly lower bass level and dynamics near maximum volume. If you are AC connected and playing via your Xtreme speaker, you will hear an increase in bass performance. The reason that bass performance is lowered when playing on battery is to reduce power consumption for you to have longer playing time from your Xtreme speaker.
If I pair my Bluetooth speaker to my phone, and record a video with the phone, will the speaker's microphone serve as audio source?
No, all recordings made on the telephone will be using the telephone's built-in microphone. Replay of the recording will be heard over the speaker afterwards, though, as long as it is paired to the telephone.
Buttons unresponsive when plugged into a power source
If the buttons on your portable speaker are not working properly or are unresponsive while plugged into a power source, please try running the speaker on battery. If the buttons perform correctly while running on battery, this means your power supply is not providing enough current/amps. Be sure to use a power supply that has a rating equal to or greater than the amperage rating indicated in your product specs.

What is the difference between the 5000 and the 10000 mAH battery size stated on the box?
The physical battery has a capacity of 5000mAh @7.4V. This is the charged battery storage. When outputting ( so power from the battery is drawn ), it's using 3.7V, so half of the voltage, which will give you 37Wh - equivalent to a 10.000mAh battery with power stored at 3.7V

First, your Android device must have 5.0 OS (Operating system) or higher to support JBL Connect app. Devices under 5.0 OS will not be supported.
