JBL Free X

It is not uncommon to have charging problems with True Wireless headphones. You may encounter that charging stops, does not start at all or that one of the ear buds suddenly switches on and begins the pairing process. This is almost always caused by dirt on the metal 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 clean all contact points, on each earbud and on the charging case.
You will need: cotton cloth or makeup swab, cotton swabs and rubbing alcohol. Also a pencil with eraser for further cleaning.

Use a cotton swab with some rubbing alcohol to clean the charging terminals of the headphones. Rotate the swab and scrub lightly on each contact surface, then use a cotton cloth to remove any dust and cotton residue left on the headphones. It is important to perform this process periodically to keep your headphones clean, thus avoiding affecting the charging speed/quality.

Wipe the contact pins in the charging case with a clean cotton swab. The swab can be slightly moistened with rubbing alcohol, but it is important that the interior is completely dry before closing the box. Use the cotton cloth and wait for it to dry.

Repeat until the contact points are visibly clean, and charging should work as designed.

Try cleaning the contacts with the tip of a pencil and the eraser at the end of the pencil, the graphite and rubber can help to re-establish charging also.
This procedure can be performed on all TWS earphones and cases.

This headphone does not feature volume control. You must manually control volume from your device.

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.

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.

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.

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.

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