Hi, Does the red charging light turn on when you connect a compatible charger to the headphones to charge the battery? ''It not'' it may be that the charge port is faulty or loose from the board and therefore the battery won’t be charged so that the headphones work or perhaps the battery is faulty. Use a strong light and a magnifying glass to visually inspect the charge port to ensure that there is no obstructions preventing a good connection and that the pins are a;ll staright and parallel with each other and not bent, broken or missing. Here’s a link to a [https://www.youtube.com/watch?v=VAHaVWFBtF4|video] that shows how to open the headphones so that the port and the battery can be accessed.
