Hi RIJWAN AHAMAD, If your JBL speaker produces distorted sound, see the JBL Charge 3 Sounds Distorted problem page for possible problems and solutions. I’m sorry to hear about this issue, you should reach out to JBL, and check your device’s warranty status before attempting a self-repair, it is possible that your speaker is beginning to die, or it was damaged, and if the device is under warranty you can work with JBL to get it replaced. Best of luck.
