INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A communication device and a communication method thereof are provided. The communication device includes a communication chip, a host processor, an audio processor, and a switch. The host processor includes a communication protocol module and a headset profile module. The audio processor includes an audio profile module. The communication protocol module supports a communication protocol including a headset profile, an audio profile and more profiles. The communication protocol module forms a first connection with a wireless headset. The headset profile module supports the headset profile. The audio profile module supports the audio profile. The switch selectively and electrically connects the communication chip to the host processor or the audio processor. When the audio processor executes a music play procedure, the communication protocol module suspends the first connection. After forming a second connection with the wireless headset, the audio profile module outputs a music package to the communication chip. ## Claims ### Claim 1 A communication device, comprising: a communication chip;
