Control of audio system via context sensor

The invention describes a control of an audio system via a context sensor. Embodiments related to the control of a computing device via an audio output apparatus having a context sensor are provided. One disclosed embodiment provides a computing device configured to receive a first input from a context sensor on an audio output apparatus, and to activate a selected listening mode based on the first input, wherein the listening mode defining a mapping of a set of context sensor inputs to a set of computing device functionalities. The storage subsystem further includes instructions executable by the logic subsystem to receive a second input from the context sensor after activating the selected listening mode, and in response, to selectively trigger execution of a computing device functionality from the set of computing device functionalities based on the second input, and to transform an audio signal supplied to the audio output apparatus based on the selected computing device functionality.
