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.
