Pairing issues with a Computer or PC
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 deviceAlways 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.The standard drivers provided by Microsoft/Windows system are not correct and will result in error messages (such as having to enter a PIN code), or pairing will not work.

Cleaning Instructions for Re-establishing Charging
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.
TalkThru Technology
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.
How to Turn off your TWS Headphones
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).
Fit and Sizing
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.
Manually Connecting
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.
