JBL PORTABLE APP

For complete control over the Xtreme 4 you will need to download the JBL Portable App.

Once you finish following the app instructions the Xtreme 4 will appear under your available devices.

Thanks to the Auracast feature you can cover much larger spaces by adding many PartyBoost JBL portable speakers together.

From inside the main tab, you can check battery life and if there's a firmware update like in my case that alert is going to cover much of the screen.

You can of course use the equalizer function from the main tab, enable PlaytimeBoost (eco mode for 6+ extra hours of music playback), use the Stereo Group function and check product information.

Finally, from inside the product information page you can rename the speaker, enable/disable feedback tones and reset the speaker to its factory settings.
