A wireless communication headset having both wired and wireless modes is provided. The wireless headset can include a headset connector assembly that can be coupled to a cable connector of a cable, which can in turn be connected to a telephone. When the wireless headset is coupled to the telephone, it can advantageously be operable to exchange audio information with the telephone through the cable, receive electrical power from the telephone through the cable, or both. In addition, the cable connector can advantageously be coupled to the wireless headset without obstructing airflow to a microphone that is located in the headset connector assembly, through use of apparatus of the invention located on the cable connector, such as an acoustic tunnel, a microphone-speaker pair, or a microphone that is coupled to control circuitry operable to disable the microphone of the headset.
