JBL Tune Flex True Wireless Bluetooth Noise Canceling Earbuds

We appreciate your feedback. Since you mentioned that there is no light indicator on the right earbud, it is possible that this is a charging issue, and it is frequently caused by foreign matter on the metal charging contacts, which can include sweat, grease, earwax, and more. These issues can often be resolved by cleaning the contact points on the earbuds and the charging case. Please note that your JBL Tune Flex comes with a 1-year manufacturer's warranty. For further assistance, please contact our customer support.

We appreciate your review. We're here to help. Our JBL Tune Flex's Active Noise Cancellation (ANC) is optimized for general ambient sounds (e.g., commute, office), and may be less effective in very high-decibel, industrial environments. Regarding rain exposure, the unit is IPX4 rated, meaning it's resistant to splashes and sweat (suitable for workouts), but heavy rain can sometimes impact performance. For touch sensor, and sound quality issues, please factory reset the unit: With both earbuds on, and not charging, tap two times and hold the button on the third tap for more than 5 seconds. Finally, place the earbuds back into the charging case to complete the process. You may need to 'forget' the headphones in Bluetooth settings on your phone/tablet in order to pair them again. For charging case connection issues, cleaning the contact points on the earbuds and charging case usually resolves them.

The unit is IPX4 rated (splash and sweat-resistant for workouts), but heavy rain can impact performance.

For optimal bass, first use the "Check My Best Fit" feature in the JBL Headphones App to ensure correct ear tip size and positioning. If bass issues persist, consider your audio source quality, EQ settings, or the source device. For intermittent bass, try adjusting your EQ or checking app/service settings. If bass is consistently lacking, toggle your EQ (on/off or boost), test with a different device, or perform a factory reset as a last resort. 4.

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.

Thank you for bringing this to our attention. To achieve the best seal and secure fit, you must create a tight seal within your ear canal. To do this, angle the ear tip slightly downward to make it easier to insert into your ear canal, gently twist the earbud to fit it securely into the shape of your ear, and continue twisting the earbud into your ear canal. You may also try using the different sizes of eartips for our JBL Tune Flex. Regarding the volume issue with your earbuds, please connect them to your other devices to see if the same issue occurs. 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.
