Abstract: An ear hook for a wireless headset includes a carrying portion and a joint portion. The carrying portion has a first connection, a power control circuit and a battery unit, and the joint portion has a second connection. The first connection is connected with the second connection in a separate fashion. When there is a voltage input detected at the first connection, the power control circuit applies the voltage output at the first connection to charge the battery unit, and when there is no voltage input detected at the first connection, the power control circuit sets the battery unit to discharge. Therefore, when the carrying portion is connected with the joint portion, the battery unit inside the carrying portion discharges, and when the carrying portion separates from the joint portion, it is connected with a transformer via the first connection to charge the battery unit.
