Thanks for reaching out. Our JBL Live Free NC+ TWS earbuds are sold as a pair, and we do not sell individual earbuds for this unit.

You can enable the Ambient Aware feature of the JBL Live Free NC+ TWS by tapping the touch control of the left earbud. The JBL headphones app is not required to be running at all times when using this feature.

Thanks for reaching out. It is recommended that you charge both earbuds together. If you have charging problems, the first step is to always clean all contact points, on each earbud and on the charging case. 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. 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. Try cleaning the contacts with the eraser at the end of the pencil, the graphite and rubber can help to re-establish charging also. If you're still having issues charging your headphones, you may reach out to JBL Customer Service for technical support and assistance. https://bit.ly/2WocMfi

This resets the earbuds without restoring the settings to the factory defaults. Please remove/delete the old Bluetooth profile of your headphones before pairing and connecting.
