A wireless headset receives audio data wirelessly from a television receiver and outputs audio to the user through earphones. The wireless headset includes an inertial sensor that detects an orientation of the user's head. If the orientation of the user's head indicates that the user is sleeping, then wireless headset turns off the wireless receiver, thereby saving battery life.

1. A method, comprising: receiving, in a media device, audio data and video data of a media program;storing the audio data and video data of the media program in a buffer;powering a wireless headset with a battery positioned within a housing of the wireless headset;broadcasting, from the media device, an audio portion and a video portion of the media program;receiving, from the media device, in the wireless headset worn by a user, an audio portion of the media program;monitoring, in a sensor, a physical state of the user;detecting, in the sensor, that the user has fallen asleep based on the physical state;turning off a wireless receiver of the headset in response to detecting that the user has fallen asleep;transmitting a first signal from the wireless headset to the media device in response to the wireless headset detecting that the user has fallen asleep; andrecording the media program in its entirety, including going back and recording the media program from its beginning using the audio data and video data of the selected media program stored in the buffer, in response to the media device receiving the first signal transmitted from the wireless headset in response to the wireless headset detecting that the user has fallen asleep;transmitting a second signal from the wireless headset to a device coupled to the media device in response to the wireless headset detecting that the user has fallen asleep; andturning off the device coupled to the media device in response to the device coupled to the media device receiving the second signal transmitted from the wireless headset in response to the wireless headset detecting that the user has fallen asleep. 2. The method of claim 1 wherein the sensor is an inertial sensor coupled to the wireless headset. 3. The method of claim 2, comprising determining that the user has fallen asleep based on movements of the user's head detected by the inertial sensor. 4. The method of claim 3, comprising detecting that the user has fallen asleep if the headset has a particular orientation for a period of time longer than a threshold time. 5. The method of claim 2 wherein monitoring the physical state of the user comprises detecting, based on the output of the inertial sensor, an orientation of the headset. 6. The method of claim 5 wherein the orientation indicates that the user's head is no longer upright. 7. The method of claim 1 wherein the sensor includes a microphone and monitoring the physical state comprises monitoring the user's breathing using the microphone. 8. The method of claim 1 wherein monitoring the physical state comprises monitoring whether eyes of the user are shut. 9. The method of claim 1 wherein monitoring the physical state comprises monitoring a heart rate of the user. 10. The method of claim 1, comprising outputting a prompt on a display indicating that the media device will be powered down unless a user input is received in response to detecting that the user has fallen asleep. 11. The method of claim 1, comprising turning off the media receiver in response to receiving the signal in the media receiver. 12. The method of claim 10, comprising turning off a television coupled to the media receiver in response to receiving the signal in the media receiver. 13. The method of claim 1, comprising turning the wireless receiver back on in response to detecting that the user has woken up. 14. The method of claim 1 wherein modifying the output of the media device includes pausing the media program. 15. A method, comprising: receiving, in a television receiver, audio data and video data of a selected media program;storing the audio data and video data of the selected media program in a buffer;transmitting the audio data of the selected media program from the television receiver to a wireless headset;receiving, in the television receiver, a user input selecting a condition for transmitting a power-down signal to the wireless headset;transmitting the power-down signal to the wireless headset and a device coupled to the television receiver; andrecording the selected media program in its entirety, including going back and recording the media program from its beginning using the audio data and video data of the selected media program stored in the buffer, upon fulfillment of the condition for transmitting the power-down signal to the wireless headset. 16. The method of claim 15, comprising outputting a prompt on a display indicating that the television receiver will be powered down unless another user input is received. 17. The method of claim 15 wherein the condition is a particular time of day. 18. A wireless headset, comprising: a wireless receiver configured to receive from a media device an audio portion of a media program;a speaker configured to output the audio portion to a user of the wireless headset;a sensor configured to monitor a physical state of the user and to output a sensor signal indicative of the physical state;a controller coupled to the wireless receiver, the speaker, and the sensor and configured to receive the sensor signal and to turn off the wireless receiver when the sensor signal indicates that the user has fallen asleep; anda transmitter coupled to the controller and configured to transmit a first signal from the wireless headset to the media device and a second signal from the wireless headset to a device coupled to the media device in response to the sensor signal indicating that the user has fallen asleep, the first signal being configured to cause the media device to record the media program in its entirety, and the second signal being configured to cause the device coupled to the media device to turn off. 19. The wireless headset of claim 18 wherein the sensor is an inertial sensor configured to monitor an orientation of the headset. 20. The wireless headset of claim 19 wherein the controller is configured to turn off the wireless receiver when the sensor signal indicates that the user's head has not been upright for a period of time longer than a threshold time.
