The wireless communication apparatus includes a blue tooth wireless earphone that can be operated independently and a network phone base. The blue tooth wireless earphone is embedded into the network phone base. When the blue tooth wireless earphone is used independently, a voice is inputted and outputted via a microphone and a loudspeaker of the blue tooth wireless earphone, respectively. Once the blue tooth wireless earphone is used in combination with the network phone base, the voice is inputted and outputted via a microphone and a loudspeaker of the network phone base. The blue tooth wireless earphone is also used independently to be connected to a blue tooth mobile phone, a PDA, etc. Furthermore, by being connected to an external apparatus through a USB interface, the blue tooth wireless earphone is charged by the network phone base, and such a design is also applicable in a hands-free car earphone.
