UA True Wireless Flash X - Engineered by JBL

To pause/play music, tap center button on right or left ear for 1 second. To skip tracks forward, DOUBLE CLICK the center button on right or left ear. Unfortunately, you cannot skip tracks backward.

To activate the voice assistance, press and hold the center button on the RIGHT ear for 2 seconds until you hear your music stop. You will be able to speak to VA through your headphones and it should comply with your command.
 

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

Try all Flex Fit Ear fins included (S/M/L) to find a snug fit for stability during workout. Usually the biggest size that fits comfortably in your ear will provide the most stability. Try all ear tip sizes (S/M/L) to find a snug seal for optimum sound quality, and look for a balance of comfort and acoustic sealing.

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.) It also may be necessary to remove or forget the earbuds from the list of paired Bluetooth devices in order to pair again.

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.

The Left and Right bud should sync together automatically when removed from the case. If the Left and Right bud do not sync together automatically within 15 seconds, you may manually sync the buds together. With the buds out of the case, press the center button on each bud 3x. This action does not have to be done simultaneously. You may start with either the L or R bud to initiate syncing.

1. Put the earbuds back into the charging case and close the lid. 2. Press and hold the buttons on both the left and right earbuds for more than 2 seconds. Alternatively, only press and hold one of the buttons to just turn off the left or right earbud as required. 3. Use the Auto-off function via the JBL Headphone app (Only applicable for headphones supported in our JBL Headphone app).

This headphone does not support aptX, aptX HD, aptX Low Latency audio codecs.

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.

To activate TalkThru Technology, press the LEFT ear for a short press for 1 Second which allows you to clearly hear others for quick conversations without removing headphons. Music volume level should lower when TalkThru is engaged. Press again for 1 second to turn off Talk Thru.

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.

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.

If the left ear pod is silent, please perform a new pairing with the right pod like shown in the quick-start guide.
Take them out of the charging case and click the  center button on both the left and the right pod 3 times.
This forces a new pairing between the pods, and the left pod should automatically pair with the right pod from now on once you remove both pods from the charging case.

If you still cannot get the Left ear to play, please perform a factory reset by placing both pods in the charging case, while the charging case is charging. Now press the button on the right pod, and hold it for more than 5 seconds. You have now reset to factory settings. (Please note: If you have performed a factory reset, you will need to remove the headphones or "forget this device" from any smart phone or tablet they were once connected to. This will allow your device to now search for the newly restored headphones under BT devices)


The right pod is the primary, which is connected to your source, usually a smartphone.
The left pod is the secondary, which connects to the right pod.
 

To power on and pair the headphones, remove the ear tips from the charging case. If this is your first time using the headphones, they will automatically go into pairing mode. You will see the blue and red LED light flash on the RIGHT and LEFT ear as it attempts to pair with your device. Make sure your device is in range and BT settings are ON. The JBL True Wireless Flash X should pop up on your list of discoverable devices within 3-5 seconds, tap and connect. Once connected, you will see a slow blinking blue light below the UA logo on the RIGHT and LEFT Ear. This headphone allows you to use the ear tips in Stereo or Mono mode. If you wish to just use the LEFT or RIGHT ear, simply place the ear tip you do not wish to use back in the charging case.

• 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.

If you are experiencing issues getting the app to communicate with your headphones, (assuming you have already paired the headphones with the device) go into the communication apps audio settings. You will likely find the resolution there. You may have to set your headphones as the ‘communication device’ within the app you are using.
