How To

Many Harman Kardon, JBL and AKG products run on rechargeable batteries. In most cases, these batteries will provide years of excellent service and keep the music playing for many hours.

WARNING – the rechargeable batteries inside our products are not user-serviceable. Please do not attempt to open the product or replace the battery. Doing so will void your warranty.

Battery issues fall into three categories:

• Your speaker or headphones run out of power after only a short time.

• The speaker will not play at all because the battery will not hold a charge.

• When you plug in the cable to charge your speaker, sometimes it charges and sometimes it does not- the red charging LED or other indicator might not come on.

  Here are some things to try that often fix these issues.

1. It could be as simple as a bad USB charging cable. If you have other charging cables, give them a try. (Be sure that the cable has the same type of connector as the original one that came with your product.)

2. Same for the charger- if your product charges by USB, try a different USB charger. Be sure that it is rated at least 2.0a (2 amps) output.

3. Try other electrical outlets at your location to be certain it is not a local wiring issue.

4. Charge the product overnight for at least 8 hours.

5. When you plug the charging cable into the speaker or headphones, is the connector stable, or can it be wiggled around? If it can be wiggled, this could indicate that the charging port has been damaged or come loose. Sometimes wiggling the connection restores charging power.

IMPORTANT: Some products such as Xtreme, Xtreme 2, Boombox, Partybox 100 & 300, GO+Play and the Onyx Studio series do not use USB charging. Instead, they have a specialized charger. Do not attempt to charge these products with other cables or chargers.

If none of these fixes the issue, it could be that the battery has died or is losing its capacity, or that the charging connector on your speaker is damaged. Please contact us so we can assist you. Be sure to mention that you have tried the steps in this Battery & Charging FAQ so that our agents do not ask you to repeat these steps.

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.

Harman continuously strives to improve the performance of our speakers through software updates in the JBL Portable App. To optimize battery life and performance for your speaker, please perform a software update:
First download the JBL Portable App from the App store or Google Play store to your mobile device.
Then connect to the speaker by Bluetooth.
Open the JBL Portable App and select settings to check and install the new Software version.
The red dot indicates the presence of an update (see image below).

Three things to know about Bluetooth (BT)… 
   

1. For most speakers, quickly press and release the speaker’s BT button.  However, with some speakers you may have to press and hold the BT button for a few seconds.  Most speakers make a noise or have a blinking LED to let you know they are in pairing mode. 
   
   If this does not get you into pairing mode, check your owner’s manual or look for an article pertaining to your specific speaker.
2. Go into BT settings on your phone.  Search or scan for available devices.
3. A list of available or discoverable devices will appear on your phone.  Select your speaker.
4. Two things have just occurred:
   • Your phone and speaker are now paired.
   • Your phone and speaker are now connected so that you can listen to music.

 

• Some phones may not work like this.
• Someone else may have connected to the speaker.
• Perhaps you connected to a different speaker while outside of your home.

• Go into Bluetooth settings on your phone and make sure BT is on.
• Select your speaker to re-connect and play music.

• Go into the other phone’s BT settings and disconnect the speaker or turn off BT.
• Then follow the steps above to manually re-connect your phone to the speaker.

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.

To take a phone call, tap the center button of the right or left ear for 1 second. To hang up a call, tap and hold the center button for 1 second. To ignore a call, tap and hold center button for 3 seconds until music resumes. You may also use the ear buds in MONO or STEREO mode which allows you to make a call or listen to music on either bud independently.

Yes, anyone that is near your JBL LINK speaker can get access to previous search history or information about Calendar, Google, Gmail etc., if you have shared this kind of information with the LINK speaker.

No, this is not possible. Siri is activated by pressing the play-button for some seconds. Since the play-button on the headphone doubles as on/off button, pressing and holding it will simply turn the headphone off.

Boost TV is not designed to be wall-mounted. It is designed to be surface-mounted underneath a television.
