1. A method comprising:
- determining with a wireless headset a first angular position of the wireless headset;
in response to the determining, defining a size of a cone-shaped noise cancellation region for the wireless headset based on the determined first angular position;
after the defining the size, receiving with the wireless headset an audio signal; and
in response to the receiving the audio signal, processing the received audio signal based on the defined cone-shaped noise cancellation region.

Abstract
This includes systems and methods for accelerometer usage in a wireless headset. An accelerometer can be used to determine the location of a wireless headset. The determined location can be used to control and improve a noise cancellation system. In some embodiments, the determined location can be used in controlling the functions of buttons of the wireless headset. In some embodiments, the accelerometer can further be used to determine when the system is in use. If the system has not been in use for a predetermined amount of time, at least a portion of the wireless headset can be turned off to save power.
