3. The method of claim 2 , wherein:

the audio information associated with the companion communication device comprises audio information corresponding to a voice call application.

4. The method of claim 2 , wherein:

the audio information associated with the companion communication device comprises audio information corresponding to a media application executing on the companion communication device.

5. The method of claim 1 , wherein:

changing the display of the user-selectable control for routing audio information comprises removing an option associated with the wearable audio output device as an audio route.

6. The method of claim 1 , wherein:

changing the audio output operation of the companion communication device comprises pausing output of audio information by the companion communication device.

7. The method of claim 1 , wherein:

changing the audio output operation of the companion communication device comprises un-publishing, by an operating system component, availability of an audio route associated with the wearable audio output device.

8. The method of claim 1 , wherein:

the wearable audio output device comprises at least one ear bud of a pair of ear buds; and

the wearing status indicates whether the at least one ear bud is being worn by a user.

9. A wearable device comprising:

a processor;

a speaker;

a sensor configured to determine a change in wearing status of the wearable device; and

a communication interface configured to pair the wearable device with a companion communication device and to send a first signal to the companion communication device to cause the companion communication device to:

detect, based on a signal received from the wearable device, a change in wearing status from a first wearing status that indicates the wearable device is being worn to a second wearing status that indicates the wearable device is not being worn; and

change, based at least in part on the change in wearing status of the wearable device, display of a user-selectable control for routing audio information associated with one or more applications executing on the companion communication device.

10. The wearable device of claim 9 , wherein:

the communication interface is further configured to receive audio information associated with the companion communication device, and

the processor is configured to generate an audio output signal, for output by the speaker, based on the received audio information.

11. The wearable device of claim 9 , wherein the first signal to the companion communication device causes the companion communication device to:

select an audio route from at least two possible audio routes based on the change in wearing status; and

send, based on the audio route, audio information associated with the companion communication device to an audio output of the companion communication device instead of to the wearable device.

12. The wearable device of claim 9 , wherein change display of the user-selectable control for routing audio information comprises:

removing an option for the wearable device as an audio route.

13. A companion communication device comprising:

a wireless communications interface configured to communicate with a wireless ear bud;

a speaker for outputting audio;

a processor coupled to the wireless communications interface; and

a memory storing instructions that, when executed by the processor cause the companion communication device to perform operations including:

detecting, based at least on a signal received from the wireless ear bud, a change in wearing status from a first wearing status indicating that the wireless ear bud is being worn to a second wearing status indicating that the wireless ear bud is not being worn; and

changing, based at least in part on the change in wearing status of the wireless ear bud:

a behavior of the companion communication device; and

display of a user-selectable control to route audio information associated with one or more applications executing on the companion communication device.

14. The companion communication device of claim 13 , wherein changing the behavior of the companion communication device comprises:

selecting an audio route from at least two possible audio routes based on the change in the wearing status; and

sending, based on the audio route, audio information associated with the companion communication device to an audio output of the companion communication device.

15. The companion communication device of claim 13 , wherein:

changing the display of the user-selectable control to route audio information comprises removing an audio route option associated with the wireless ear bud.

16. The companion communication device of claim 13 , wherein:

changing the behavior of the companion communication device comprises pausing audio information of the companion communication device.

17. The companion communication device of claim 13 , wherein:

changing, based on the change in wearing status, the behavior of the companion communication device comprises un-publishing, by an operating system component, availability of an audio route associated with the wireless ear bud.

18. The companion communication device of claim 17 , wherein:

un-publishing the availability of the audio route associated with the wireless ear buds disallows selecting, on the companion communication device, the wireless ear bud for audio reproduction.

19. An apparatus for operation in a companion communication device, the apparatus comprising:

a processor communicatively coupled to a memory storing instructions that, when executed by the processor, configure the companion communication device to perform actions including:

detecting, based on a signal received from a wearable audio output device, a change in wearing status from a first status to a second status; and

changing, based at least in part on the change in wearing status of the wearable audio output device:

an audio output operation of the companion communication device; and

display of a user-selectable control for routing audio information associated with one or more applications executing on the companion communication device.

20. The apparatus of claim 19 , wherein changing the audio output operation of the companion communication device comprises:

selecting an audio route from at least two possible audio routes based on the change in wearing status; and

sending audio information associated with the companion communication device to an audio output of the companion communication device when the change in wearing status indicates that the wearable audio output device is not being worn.

21. The apparatus of claim 19 , wherein:

changing the audio output operation of the companion communication device comprises pausing output of audio information by the companion communication device.
