JBL Boombox 2 - What's in the Box

FAQs & How-Tos

JBL Portable App: PC Information
You cannot download the JBL Portable App on a PC. This app is only available on mobile devices.
My device is waterproof, but what about salt water or chlorine water?
Your JBL speaker is waterproof with IPX7 rating. (IPX7 means it can survive immersion in 1 meter/3.3 feet for up to 30 minutes.) To maintain the looks and functions of your speaker, please make sure to rinse it with fresh water after using it at a swimming pool or the ocean, then dry off all covers and areas where water can gather. The standard for waterproofing is for tap water. Chemicals and salt in your pool or the ocean can damage the waterproof seals or harm the surface finish over time if not rinsed off after use.
Upgrading the software on your PartyBoost or Connect+ Speaker

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.


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.

Pairing issues with a Computer or PC
In most cases when a Computer/PC/Laptop has issues connecting to a Bluetooth device (Portable speaker, Headphones, Active speakers), it's caused by your Computer/PC/Laptop's Bluetooth driver (software).

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.

The standard drivers provided by Microsoft/Windows system are not correct and will result in error messages (such as having to enter a PIN code), or pairing will not work.
Battery Capacity Specifications
The Boombox 2 features the same battery capacity as the first generation Boombox. The Boombox 2 battery specs have recently been changed in measurement specifications but still provides up to 24 hours of audio playback.
Indoor/Outdoor Mode

The new Boombox 2 does not feature the Indoor/Outdoor Mode. With the first generation Boombox, the Outdoor Mode was loud, but lacking sufficient bass. The Boombox 2 has both improved bass and loudness to create the perfect balanced sound for all environments.

 
 
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.
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.
Issues with the JBL Portable App and your Android device
There might be several reasons that our Portable app may not be working correctly on your Android device. 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. If you are having trouble viewing your JBL Portable device in the app, please disable Bluetooth, and then turn it back on again. Now you should be able to see your device in the JBL Portable app.
Does my Speaker have Speakerphone/Voice Assistant Functionality?
This product does not feature speakerphone or voice assistant functionality as it does not have a microphone.
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.
Charging the Speaker When Wet
You will need to dry the charging port completely before plugging in power for charging.
 
Renaming of the JBL Connect App to JBL Portable
The JBL Connect app will be renamed as JBL Portable on the App Store and Google Play store in January 2021, it will still be possible to find the app in each store by searching for either JBL Connect or JBL Portable.
Audio distortion or drop outs while using JBL PartyBoost or Connect+

If you are having trouble with distortion or drop out, try the following suggestions:

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

2. Support for PartyBoost under aux-in connection.

PartyBoostBluetoothButton.png
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. PartyBoostButtonsGroup.png
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.
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.
Waterproof Information (IPX7)

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.
