Sorry, there was a problem. Please try again later.We're here to help with your JBL Tune 230NCTWS. Charging issues could be one of the reasons why the earbuds are not working properly and these are frequently caused by foreign matter on the metal charging contacts. We recommend cleaning the contact points on the earbuds and charging case to see if it helps. If the issue persists, please contact our customer support service via our official website or toll-free hotline.
