FAQs & How-Tos

As with all in-ear headphones, our range of True Wireless Stereo headphones can be susceptible to a build up of dust and earwax. This can cause low volume on one or both earbuds, or balance issues (e.g. right earbud is louder than the left earbud). To reduce the likelihood of these issues occurring, it is a good idea to periodically clean your earbuds. Clean the earbuds by removing dust and wax after each use, using a pointed toothpick to remove larger amounts and a small amount of rubbing alcohol applied to a cotton swab for final degreasing. Remember to clean the charging points on the headphones and inside the charging case.
If you are experiencing volume or balance issues, always check for wax and dirt in and around the earbud and driver and complete cleaning of the earbuds as described above. If the issue persists, there may be earwax/dirt stuck in the small holes in the grille in front of the driver, preventing sound output. To resolve the issue try dipping the affected earbud tip into a solution of lukewarm tap water and a small amount of dish soap (washing up liquid). The earbud tip should only be put into the liquid up to a maximum depth of 1-2 mm only (see images below). Immersing the earbuds in water or putting the earbuds in water at a larger depth than this could void your warranty. Keep the earbud tip in the water for about 2-3 minutes, then wipe/clean the grille with a small brush (such as a toothbrush). This should remove the wax and resolve the volume/balance issues.

The JBL product is in a deep sleep mode, which it is to prolong the lifetime of the battery. Connect the case to a charger for about 2 seconds to wake the product up and take the earbuds out from the case. Once you put the earbuds back in the case, it's ready to pair through Bluetooth.

Double-tap the button on the right earbud, then on the third tap - press and hold the button for more than 5 seconds (until the unit shuts off).
This restores the earbuds to the factory defaults.
TWS must be connected to perform the reset, so neither of the earbuds should be off or in the charging case.
It also may be necessary to remove or forget the earbuds from the list of paired Bluetooth devices in order to pair again.Was this helpful? Thank you for your feedback! -
PSAP (Personal Sound Amplification) is a new feature accessible within the JBL Headphones App. When this feature is turned on, it works similar to Ambient Aware, but it focuses on picking up vocal frequencies in front of you.
1. GAIN: The Personal Sound Amplification function is designed to amplify sound in the vocal range, it can assist users with (limited) hearing loss to maintain conversations more easily, especially in noisy environments. It should then amplify the speech of the person sitting across from you, not the general ambient sound as with Ambient Aware. The algorithm uses beamforming to pick out the voice from the other sounds, much like what happens during a phone call, but instead of focusing on your own voice it focuses on the voice further away from you. The gain setting allows you to amplify those vocal frequencies.
2. BALANCE: The balance setting adjusts the amplification effect between your left and right ears using the slider. When set to 0 (in the middle), both ears will receive the same amplification, but depending on the user’s personal needs/preferences, they can focus the amplification more towards either the left or right ear.
