Massive sound. All day long.
We just made our most powerful portable Bluetooth speaker even better. The iconic silhouette of the JBL Boombox 3 has a bold new update featuring a sturdy metal handle with silicone grips, twin sidecaps, and waterproof and dustproof signature fabric. It’s been redesigned inside too, added with a new subwoofer unleashing much deeper bass and massive JBL Original Pro Sound, all with lower distortion. And 24 hours of play time takes you all the way from your morning workout to a late-night hang with your friends. And for sound that’s practically limitless, instantly connect multiple speakers with the JBL Portable app.

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.

4. Open the JBL Portable app.
5. Allow the app to detect the single speaker playing music.
6. Once detected, press the Connect/Partyboost button on both speakers.
7. Allow the app to identify both speakers.
8. Click the Partyboost button, you will see the option for Party or Stereo, select Stereo.
Please note: Stereo Mode can only be enabled when 2 of the same speaker model are used.
For example, you will not be able to achieve Stereo Mode with a Flip 5 and Flip 6, only Party Mode.
Also, it is not possible to pair speaker models with Connect and Connect+ together, or pair to speaker models with Partyboost.Was this helpful? Thank you for your feedback! -
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.Was this helpful? Thank you for your feedback!
