JBL Tune Flex True Wireless Bluetooth Noise Canceling Earbuds

Thanks for your feedback. In order for our JBL Tune Flex to give you the best audio response, you must create a tight seal within your ear canal. To achieve the best seal and secure fit, try to angle the ear tip slightly downward to make it easier to insert into your ear canal, then gently twist the earbud to fit it securely into the shape of your ear. It is best to try this with all of the provided sealing ear tip sizes until you find the one that accomplishes this most easily. If you need further assistance, please contact us.

Thanks for your feedback. We're always looking for ways to improve. For our JBL Tune Flex, we recommend cleaning the contact pins on the case and the earbuds using a cotton swab with alcohol. These pins are sensitive to dust. Please ensure the pins are dry before placing them back on the case. If the issue persists, please contact our customer support.

If it does, please follow these reset steps: take both earbuds out. Make sure that they are not connected to any Bluetooth. Press either the left or right earbud three (3) times then hold it on the third tap for 5 seconds. Once done, put back both earbuds inside the charging case for 10 seconds while the lid is closed, and connect them again to your device. Please contact us directly for further assistance.

Thank you for your feedback. Our JBL Tune Flex has up to 32 hours of battery life. This may vary depending on volume and music content. Please try charging both earbuds to 100% and then listen to music without any bass boosted, and at a very low volume. If it lasts close to the published up-to playtime, the battery is working fine. However, if you get less than 90% of the published spec, this likely means that the battery is losing its capacity. Please contact our Customer Support, so we can assist you.
