@devin7933 not sure how you are charging it but you want to make sure that the charger works. Next, check the charging cable connectors to ensure they are not bend etc. After that, check the DC-in jack on your headphones. Make sure there is no corrosion, debris etc. that prevents it from working. Clean it of any debris by using a few puffs of air to clean it out. After that, it's time to open it and check the board for an loose wires and time to replace the battery. [guide|170164]
