FAQs & How-Tos

  • JBL Free: Manual Re-pairing to Bluetooth Devices

    In the event that ear pieces do not re-pair automatically to paired Bluetooth device, power off ear pieces individually by press and hold the buttons for 5 seconds. To enter Bluetooth pairing mode when ear pieces are powered off, press and hold on buttons of both earpieces for 8 seconds. Re-pair the right ear piece with desired Bluetooth device when LED indicator on right ear piece alternates between blue and white LED lights.

  • JBL Free: Charging Information

    When you place the two Free earphones in the charging case, you will see a white led ring light up on both of them. At the same time, some of the four dot-leds on the charging case will light up to indicate the battery level of the case battery. When the earphones are fully charged, the white led ring goes out on each of them. When both are fully charged, the charging case charging level leds go out too.

  • Resetting True Wireless Headphones

    Place both ear pods in the charging box, while the charging box is plugged into a power source.

    Press and hold the button on the Right pod for about 5 seconds. The LED on the pod will turn off and then turn back on again.

    This restores to factory defaults.

    (Please note that charging must take place for reset to work.)


    Product information
  • JBL Free: Handsfree calls

    The JBL Free automatically switches from stereo to mono when making or taking phone calls. Voice calls will only come through the right ear piece for a more natural call experience.

  • JBL Free: Manual Re-pairing Left & Right Ear Pieces

    In the event that left and right ear piece pairing is lost, power on both ear pieces and press the buttons 3 times on each ear piece to initiate re-pair.

  • JBL Free: Volume Control

    The JBL Free X does not feature volume control. In order to adjust the volume, you must manually increase/decrease from your device.

  • True Wireless Headphone Cleaning Instructions

    It is not uncommon to have charging problems with True Wireless headphones.
    Sometimes charging may stop. You may encounter that the charging does not start at all or one of the ear buds will suddenly switch on and begin the pairing process.

    This is almost always caused by dirt on the charging contacts. 
    These contacts are vulnerable because they can easily be contaminated by sweat, skin grease, or ear wax.
    They are usually gold plated, but gold plating does not prevent surface dirt.

    If you have charging problems, the first step is to always to clean all contact points, both on each ear bud and in the charging case.
    It may not be easy to reach into the tiny holes, but a cotton swab or makeup swab may be used.  Moisten the tip with a little rubbing alcohol, then rotate it and scrub lightly on each contact surface.
    Repeat until the contact points are visibly clean, and charging should work as designed.

  • JBL Free: Pairing Information
