To charge the case, please connect the supplied micro-USB cable to any USB power supply or laptop socket then connect the other end to the socket on the charging case. You will need to ensure this is fully connected by pushing until there is a mechanical click sound and the battery indicator on the front of the case lights up.
To charge the earbuds, simply put them back into the charging case and charging will begin automatically. The earbud status light will pulse white when charging and switch off when they are fully charged.
