Customer Ratings & Reviews

Thanks for your feedback. We're always looking for ways to improve. For our JBL Tune 235NC TWS, 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. If the issue still persists, please contact our customer support.

Thank you for reaching out. With TWS ear buds, charging issues are frequently caused by foreign matter on the metal charging contacts. This can include sweat, grease, ear wax, etc.

Thanks for your feedback. To have better sound quality, you may check your device's music player app to see if the 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. Our JBL Tune 235NC headphones have active noise cancellation (ANC) feature. To activate the noise-canceling feature, tap your left earbud once. You can toggle between on, off, or ambient modes. With ambient mode, you can still hear some external sounds if you need to be aware of your surrounding. You can also adjust the ANC mode using the JBL Headphones App. For optimal noise reduction, make sure the eartips fit securely in your ears. To achieve the best seal and a 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 can also try different sizes of ear tips that came with the headphones to see if a better fit.

First, you may try to clean the charging terminals on the earbuds using a swab dipped in rubbing alcohol, as charging issues are frequently caused by foreign matter on the metal charging contacts. We also recommend cleaning the contacts with the tip of a pencil and the eraser at the end of the pencil, as the graphite and rubber can help to re-establish the connection between the earbuds and the case.
