Abstract: A portable headset 30 has a speaker 42, a radio receiver 32, and PAN circuitry 50 for receiving wireless electrical signals over a piconet such as Bluetooth. The radio receiver 32 or the PAN circuitry 50 may drive the speaker 42, and override circuitry 68 enables the PAN circuitry 50 to mute the radio receiver 32. The headset 30 may have a microphone 52. A mobile phone call incoming to a mobile phone 46 automatically causes a speech connection over the PAN to be established between the mobile phone 46 and the headset 30. The radio receiver 32 is muted and the user 44 carries on a phone conversation through the headset 30 without manually turning off the radio. Muting may be ceased upon termination of the phone call or of the PAN connection. A mobile phone user interface 56 may be used to control the radio receiver 32.
