In some embodiments, an audio responsive electronic device operates to intelligently turn on and turn off components in response to the detected presence of a user. In some embodiments, an audio responsive electronic device operates to suppress noise from the display device (or other sources of noise), and enhance audio commands from a user (or other sources of audio commands). In some embodiments, a media device is configured to adjust a transmission pattern to an audio responsive electronic device based on user position. ## Claims ### Claim 1 An audio responsive electronic device, comprising: a presence detector configured to detect a presence of a user within a threshold distance of the audio responsive electronic device;
