-
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.
