What is the proper way to charge the earbuds?

Place the earbuds correctly in the charging slots and close the lid to begin charging. When the earbuds are charging, the LED bar of the case will keep blinking. The charging will stop automatically and the indicator light on the earbuds will turn off when fully charged. You can charge the case and earbuds at the same time, or charge the case first and then the earbuds. (Page 12)
