Introduction
This guide will show you how to replace the charging port on your Sony WH-CH710N headphones.
If your headphones are not charging properly, the port may be clogged with debris or damaged from moisture or regular wear. Replacing the charging port can restore proper functionality and extend the life of your device without needing a full replacement.
Before beginning the repair, review the Sony WH-CH710N Not Charging troubleshooting page for possible solutions. If you have confirmed that the charging port is damaged, power off the headphones and disconnect them from the charger or audio cable before proceeding.
Warning: This guide requires the use of a soldering iron to desolder the charging port. If you are unfamiliar with soldering or need a refresher, refer to the How to Solder and Desolder Connections guide.
