1. A device to support a noise cancellation function, the device comprising:
- an audio socket including a microphone contact; and
an ambient noise detection module to;
receive an ambient noise data signal from a headset via the microphone contact, the microphone contact being alternatively coupled automatically to a first microphone and to a second microphone;
detect an impedance at the microphone contact; and
provide a first noise cancellation signal to a first speaker of the headset responsive to the impedance having a first value and to provide a second noise cancellation signal to a second speaker of the headset responsive to the impedance having a second value.

Abstract
Methods and apparatus for a battery-less, noise-cancellation headset compatible with 4-pin audio jack are generally described herein. An example head device to support a noise cancellation function may include a first microphone associated with a first speaker, and a second microphone associated with a second speaker. The example headset device may further include an audio plug having a single microphone contact, and a controller circuit to oscillate back and forth between coupling the first microphone and the second microphone to the single microphone contact at a predetermined frequency.

6. A method to provide noise cancellation, the method comprising:
- receiving an ambient noise data signal from a headset via a microphone contact of an audio socket;
detecting an impedance at the microphone contact, the microphone contact being alternatively coupled automatically to a first microphone and to a second microphone;
providing a first noise cancellation signal to a first speaker of the headset based on the ambient noise data signal responsive to the impedance having a first value; and
providing a second noise cancellation signal to a second speaker of the headset based on the ambient noise data signal responsive to the impedance having a second value. - View Dependent Claims (7, 8, 9, 10)
