Customer Ratings & Reviews

Thanks for your feedback. We're here to help. In order for your JBL Tune Flex to give you the best audio response, you must create a tight seal within your ear canal. First, 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. Next, check the balance control on your source device by going to the "Accessibility" settings and on your music player app, commonly found in the playback or EQ settings, and the balance control on the JBL Headphone or One App. Lastly, try to connect the headphones to a different device (phone/tablet/music player) to see if it fixes the problem. If the issue remains, please contact us at (800) 336-4525 Mon - Fri: 9:00 am - 11:00 pm (EST) Sat-Sun: 9:00 am - 5:00 pm (EST)

We appreciate your feedback. 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. For sound quality issue, this instance is sometimes caused by the quality of your source, depending on what you are listening to. You may check the music player app on your source device to see if Equalizer is engaged. If engaged, turn off the equalizer. If turning it off does not resolve the issue, turn it on again and adjust the EQ by boosting the bass to your liking. If you still find the sound quality insufficient, you can control the Equalizer through the JBL Headphones App to adjust and enhance the bass levels and desired music mode. If you have already tried this and remain unsatisfied with the sound quality, rest assured that we're always looking for ways to improve, and your feedback will be forwarded to our development team for future improvement.

Thanks for your feedback. We're always looking for ways to improve. With our JBL Tune Flex, 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. On the other hand if you're experiencing low sound we recommend trying different sealing eartip sizes if this does not resolve the issue. Our JBL tune flex is compatible with the JBL Headphones App, you can use the app to modify the sound to your preference. If this does not resolve the issue please contact our customer support.
