Thanks for reaching out. If one side of your JBL Tune 115TWS is louder than the other, it is likely caused by a build-up of dust in the grille or an unsecured seal within your ear canal. Please angle the ear tip slightly downward and gently twist the earbuds into your ear canal to achieve the best seal and secure fit with the earbuds. The in-ear headphones are also susceptible to a build-up of dust and dirt, which can cause volume imbalance issues. Please try cleaning the earbuds by removing dust or dirt using a pointed toothpick to remove large amounts and a small amount of rubbing alcohol applied to a cotton swab for final degreasing. If you need more help, please contact our customer support for further assistance.

We're sorry to hear about what happened to your JBL Tune 115TWS. Here are some cleaning steps for re-establishing charging: 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 an eraser for further cleaning. Use a cotton swab with some rubbing alcohol to clean the charging terminals of 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.

We're here to help with your JBL Tune 115TWS. We recommend cleaning the contact pins on the case and earbuds using a cotton swab with alcohol. These pins are sensitive to dust. Please ensure the pins are dried before placing them back on the case. It is also necessary to reset the earbuds by tapping one of the earbuds twice and holding it for 5 seconds on the third tap. Put the earbuds back in the case to complete the reset. Resetting your earbuds will erase all previous settings and pairings. Please remove or forget the earbuds from the list of paired Bluetooth devices before pairing them again. If you need more help, we'd like to work with you directly.
