Introduction
After using your Sony WI-C200s for prolonged periods and one earbud isn’t producing clear audio – decreased volume or no sound. The reason is that the connected wires from the earbud to the circuit board are loosened or disconnected.
Steps 5 and 6 require [guide|750|de-soldering the connections|new_window=true] on the circuit board and the earbud and soldering it in place.
Before beginning, make sure to power off the headphones completely.
***Caution***: soldering/desoldering presents potential for device damage and burns. Always solder/desolder in a well-ventilated area.
