Abstract: A headset that includes an input that receives an audio signal from an electronic equipment, and at least one earpiece having an electro-acoustic speaker for converting electrical signals to audible sound. The headset further includes at least one microphone that receives ambient sound and converts the ambient sound to an ambient sound signal. In addition, the headset includes a processing circuit formed as an integral unit with the input and the at least one earpiece. The processing circuit includes circuitry that combines the audio signal from the electronic equipment with the ambient sound signal from the at least one microphone and provides the combined signals to the at least one earpiece such that the electro-acoustic speaker reproduces the ambient sound in combination with audio from the audio signal.

Abstract: A system and method for providing an electronic device that facilitates hands-free operation of a portable communication device in a wide range of applications and environments, including use in a vehicle. The electronic device includes a detector to automatically activate at least a wireless interface based on the occurrence of one or more predetermined events. The generates a signal that directs the control circuit of the electronic device to provide power to a wireless interface to facilitate communication between the electronic device and an associated portable communication device. Once a communication link is established between the electronic device and the portable communication device, the electronic device may function as a car kit, vehicle, speakerphone, etc.
