Introdução
The JBL Live 660NC headphones (also known as JBL Live 660 NC or JBL Live 660NCBT) may need a charging port replacement if they stop charging, lose connection easily, or fail to turn on when plugged in. Before beginning this repair, you may want to visit the JBL Live 660NC Troubleshooting Page to make sure the issue isn’t caused by a simpler problem.
Over time, the charging port can wear out due to frequent use, debris buildup, or physical damage. Always power off your device, unplug all cables, and handle each component carefully to prevent further issues during the repair.
Note: You don't need to remove the battery as shown in Step 7, but be sure to disconnect the battery.
