4.1 Initial Charging

Before first use, ensure the earphones are fully charged. Connect the magnetic charging cable to the charging port on the earphones and plug the USB end into a compatible 5V charger (DC5V+/-0.25V, 100mA-500mA output current recommended) or a computer USB port. The LED display will flash while charging and show 100% when fully charged.
