Thanks for your feedback. We're always looking for ways to improve. For our JBL Tune 235NC, charge the battery to 100% and then listen to music without any bass boosted, and at a very low volume. If the battery 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. If you need more help, please contact our customer support.

We're here to help with your JBL Tune 235NC. Please check if both earbuds are charging. If yes, try to reconnect the left and the right earbuds by tapping the button of both earbuds three times. Please also unpair or forget the JBL Tune 235TWS on your source device. If manually pairing them fails to resolve the issue, please try to unpair them again and perform a factory reset. To reset the earbuds, plug the charging case into a power source and insert both earbuds. Press and hold the button on the right pod for about 5 seconds until the LED turns off and on again. Resetting the earbuds will wipe all of their previous pairings and settings, so it will be necessary to pair them again. If the issue continues, please contact our customer support for more assistance.

Thanks for your feedback. We're always looking for ways to improve. For our JBL Tune 235 NC TWS, source devices (phones, tablets, etc.) all behave a bit differently. Some have very loud outputs, and some can be quite a bit lower, even at maximum volumes. You may try to use an equalizer like JBL Headphones App on your music application to adjust the volume to your preference. If you need more help, please contact our customer support.

We're here to help with your JBL Tune 235NC TWS. This can be caused by wireless interference or a weak connection.

We appreciate your feedback. Our JBL Tune 235NC have active noise cancellation (ANC) feature which helps reduce the external noise. 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 surroundings. You can also adjust the ANC mode using the JBL Headphones App. For optimal noise reduction, make sure the ear tips 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. For volume issue, if you have already maximized the volume levels on both your source device and the earbuds itself and still find the loudness insufficient, please note that the EQ (equalizer) feature can be accessed through the JBL Headphones App to adjust and enhance the volume levels of specific frequencies in the audio signal. If you have already tried this and remain unsatisfied with the loudness, rest assured that we're always looking for ways to improve, and your feedback will be forwarded to our development team for future improvement.
