  • The Mute+ATMOS combination button press to determine the Battery Status was originally designed for production line testing, not for consumer usage.  We determined that this testing method was inaccurate and began testing using specialized external equipment.  As of Software Version V21.13.11.80, the ability to check Battery Status inaccurately has been removed.

    When charging the satellite speakers you can be confident that the Battery Status is 100% when the LED indicator goes  out.  As well, when the LED begins blinking red, you are at 20% and should recharge or plug in your speakers.
  • A dedicated bass boost button located on the RIGHT ear cup on the CLUB 950NC & 700BT increases low-end frequencies of 5-6 dB adding a kick to your favorite tracks.
  • The BASSPRO GO receives is power ONLY from the harness that is connected to the car battery.  When connected to the harness, the car battery will charge the internal battery so that it is ready to be used as a portable the next time you need it.

    When removed from the harness, the full-range portable speaker runs on the internal battery.  It cannot be charged via either of the USB (A or C) jacks.  It will be charged the next time it is connected to the harness in the vehicle.
  • The BASSPRO GO uses the original Connect feature.  It is not compatible with devices using the Connect+ or PartyBoost feature.  You can connect up to two BASSPRO GO speakers to each other using Connect, or you can connect a single BASSPRO GO to other JBL speakers that have the same Connect feature, like the Xtreme, Charge 3, Flip 3, and Pulse 2.
  • Installation of a powered subwoofer/speaker in an automobile requires specific knowledge and experience.  If you’ve read the manual and do not feel comfortable performing the installation and setup yourself, we recommend that installation be carried out at a specialized center by a professional.
  • 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).
  • Please note: this text concerns Lithium-Ion batteries only.
    If a charger (power supply) comes with your product, use the original charger.
    If you have a device with USB charging socket use chargers with capacity above the minimum listed in the product specifications. Charging using a USB charger with higher capacity is not a problem.
    It is wise to charge only where you can observe the device, so you can stop charging if overheating should occur.
    All batteries, over time, will slowly wear down. A good battery will keep more than 70% of its original capacity even after 500 charging cycles. Capacity will decrease gradually, until almost no capacity is left, and the battery will need replacing, if this is possible and economical. Life expectancy is optimal when the battery is being used between 10 and 50 degrees Celsius.
    There is no memory effect in Li-ion batteries, so do not treat them like old Nickel-Cadmium types (which you had to run dry regularly).
    This means that you should never run Li-ion batteries completely dry. Actually, this will damage the battery. Whenever you can, keep them between 20 and 80 per cent capacity, where they perform best. However, it is better to charge the battery to 100% capacity than to run it dry.
    Never charge if temperature is at freezing point or lower (0 degrees Celsius, 32 F), since this will almost certainly damage the battery. 
    Never place the device that is being charged on a sofa, rug or clothing when charging. This can cause heat to build up, which can in turn cause overheating. Always place it on a flat, hard surface, where heat can dissipate quickly.
    Most rechargeable devices use Lithium-Ion (Li-ion) polymer batteries these days.
    This type has high energy density, very low memory effect and low self-discharge.
    You can find them in electric cars, golf carts, power tools and other applications, besides portable headphones, telephones and loudspeakers.
    Various subtypes exist that have different strengths and weaknesses, depending on the chemicals and metals used.
    Batteries gradually self-discharge, even if they are not connected to anything. Usually, you can expect a self-discharge of about 2% per month when the battery is new, and this may increase somewhat with battery age and temperature.
  • JBL QuantumSURROUND technology can be used with any type of multi-channel audio content. For example: Netflix content, Blu-ray, and music mixed in 5.1 or 7.1 surround.
  • Three things to know about Bluetooth (BT)… 
    1. Pairing:  Pairing is like creating a new contact in your phone’s Contacts list.  You have to do a little bit of work to create the contact, but once you do, connecting with that person in the future is fast and easy. 

    Let’s put this in terms of phones and speakers (or headphones).  Your phone needs to become acquainted with your speaker.  This is called pairing. 

    NOTE: Throughout this article, we will talk about your phone. However, it applies the same to tablets, laptops, computers and any other Bluetooth (BT) source device.
    To get this started, you have to put the speaker into pairing mode. You may have to press a few buttons to make this happen.  All speakers work a little differently, but generally speaking, follow these steps…
    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.
    NOTE:  Just as you can have many people in your phone’s Contacts list, you can have many speakers and headphones in your phone’s paired devices list. 
    2. Connecting:  Once you have paired, your phone remembers your speaker, and your speaker remembers your phone. However, the two must connect to play music through the speaker.
    Automatic Re-connection:  Let’s say your speaker is at home in the living room, and you leave for the day. When you come home and are within range of the speaker, your phone will automatically re-connect to it (assuming it is turned on).  You can press play on your phone, and the music will play though your speaker.  Of course, if your speaker is off, you will need to turn it on first. NOTE:  Some speakers make a sound when they re-connect. 

    Automatic re-connection does not always happen.
    • 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.
    Manual Re-connection:  If your device does not automatically re-connect, you can re-connect manually…
    • Go into Bluetooth settings on your phone and make sure BT is on.
    • Select your speaker to re-connect and play music.
    Some speakers allow several phones to be connected at the same time.  Others allow only one at a time.  Therefore, if you are unable to re-connect, it could be that some other phone is connected to the speaker.  In this case…
    • 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.
    NOTE:  Do NOT Unpair or Forget the speaker in your phone’s BT settings, as this will require you to repeat the Pairing steps above. 
    3. Resetting:  This is a drastic step and should only be done if the unit is not operating correctly. Do NOT reset your speaker every time you want to connect.  Resetting erases all pairings to all phones. You would then have to Unpair or Forget this speaker from each and every phone, and start the pairing process all over again. Check your owner’s manual or look for an article with more detailed BT instructions on your specific speaker or headphone model.

  • 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.
