charge it
You’ll need to charge your headphone’s battery before using it. Plug the charger into the charging port on your headphones (as shown below) and a wall outlet.
The indicator light is red while the battery is charging. When the battery is fully charged, the indicator light turns green.
Note: Your battery is designed to last the life of your headphones. It should only be removed by a recycling facility. Any attempt to remove or replace your battery will damage your headphones.
