JBL Boombox 3

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.

FAQs & How-Tos

How to reset Boombox
In power ON mode press and hold the "Volume +" and "Play" buttons at the same time for more than 3 seconds -> Unit will power Off by itself. Now the unit is reset to factory default.
How to avoid Bluetooth Interference or Interruptions
• Always have clear line of sight between your Bluetooth device (speaker, headphones etc.) and source device (Smartphone/tablet/PC etc). Be aware of obstacles in front of your devices.

• 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.
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 your Partyboost Speakers in Stereo Mode

1. Turn on both speakers.
2. Connect your device to one of the two speakers via Bluetooth.

3. Start streaming music to that speaker (for best results play music on this speaker for more than 20 seconds before proceeding with the next steps).
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.

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.

IP67 Information
This product is rated IP67, which is different from IPX7. IP67 protects the product from submersion in 1 meter (3.3 feet) of water for up to 30 minutes. It is also resistant against dust. Dust accumulation around electronics can lead to hardware failure, so the IP67 rating is an extremely beneficial addition to this product.

Smart TV Compatibility
It is always recommended to use our range of Soundbars, such as the JBL Bar series - if you want a speaker for your Television or Smart TV as they are designed specifically for this use, whereas our Portable speakers are designed primarily for use with Phones and Tablets.

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.
