Customer Ratings & Reviews

Thank you for your feedback. To troubleshoot the issue with your JBL Tune 235NC TWS, please attempt a reset. First, remove the earbuds from the case, then tap on them twice and hold for five seconds. Afterward, place them back inside the case. You may need to forget your unit on your device to pair it again. If you need more help, please contact us.

We appreciate your feedback. Bluetooth typically performs well within a 30-foot range, but walls, obstacles, and other wireless devices can impede this. If you experience dropouts within 10 feet, there may be interference. To resolve the issue with your JBL Tune 235NC, ensure it is within 10 feet of your device with a clear line of sight (no obstacles). Try to forget/unpair the speaker on your device, and initiate a reset. To reset your unit, first make sure that the case is not charging, tap the right earbud twice, and hold the button on the third tap for more than five seconds. Lastly, try to connect the speaker to a different device to determine if the issue lies with the earbuds or the initial device you paired them with. If you need more help, please contact us at (877) 871-6755 / Mon - Fri: 9:00 am - 11:00 pm (ET) Sat-Sun: 9:00 am - 5:00 pm (ET).

Thanks for your feedback. Our JBL Tune 235NC should turn off and start charging once the charging case is closed. You may try to clean the charging terminals on the earbuds using a swab dipped in rubbing alcohol, as the issue can be caused by dirt on the 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. 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)

Thanks for your feedback. To raise the volume on your JBL Tune 235NC, make sure that both your source device and the earbuds are set to their highest volume levels. Activate the noise cancellation feature by pressing the button on the left earbud once until you hear a confirmation tone and see a white LED light up. You can also use the JBL Headphones App to enable or disable noise cancellation and adjust other settings. You may also initiate a reset. With both earbuds on, and not charging, tap two times, and hold the button on the third tap for more than 5 seconds. If the issue persists, please contact our customer support at (877) 871-6755 / Mon - Fri: 9:00 am - 11:00 pm (ET) Sat-Sun: 9:00 am - 5:00 pm (ET).
