6. The portable electronic accessory of claim 4 , wherein the audio interface is configured to provide the audio notifications responsive to availability of the new audio functional features.

7. The portable electronic accessory of claim 4 , wherein the audio interface is configured to provide the audio notifications responsive to the audio inputs.

8. The portable electronic accessory of claim 3 , wherein operation of the audio operating system is distributed between the one or more application processors and the one or more cloud servers.

9. The portable electronic accessory of claim 3 , wherein the one or more application processors are configured to execute the at least the portion of the audio operating system as a virtual machine to audio operating system code operated by the one or more cloud servers.

10. The portable electronic accessory of claim 1 , wherein the portable electronic accessory includes one or more headphones including the one or more speakers and the one or more microphones.

11. The portable electronic accessory of claim 10 , wherein:

the one or more headphones include truly wireless stereo (TWS) headphones; and

the portable electronic accessory includes a TWS headphone charging case including the control circuitry.

12. The portable electronic accessory of claim 11 , wherein the removable control package is removable from the TWS headphone charging case.

13. One or more cloud servers for supporting a portable electronic accessory, the one or more cloud servers comprising:

a network interface configured to communicate with the portable electronic accessory;

one or more processors operably coupled to the network interface; and

one or more data storage devices operably coupled to the one or more processors, the one or more data storage devices including computer-readable instructions stored thereon, the computer-readable instructions including:

software application code for audio software applications to be hosted by an audio operating system of the portable electronic accessory, the audio software applications configured to operate free from graphical user interface elements based at least in part on audio inputs and audio outputs at the portable electronic accessory; and

operating system support engine code that, when executed by the one or more processors, is configured to execute at least a portion of the audio operating system of the portable electronic accessory via a virtual machine emulating the portable electronic accessory, the audio operating system free of graphical user interface elements.

14. The one or more cloud servers of claim 13 , wherein the operating system support engine code is configured to instruct the one or more processors to support operation of the audio operating system by executing a cloud audio operating system.

15. The one or more cloud servers of claim 13 , wherein the computer-readable instructions further include an audio software application store configured to provide the audio software applications responsive to the audio inputs and the audio outputs at the portable electronic accessory.

16. A method of operating an audio operating system for a portable electronic accessory, the method comprising:

providing, by control circuitry of a truly wireless stereo (TWS) headphone charging case and TWS headphones of the portable electronic accessory, an audio interface of the audio operating system, the audio operating system free of graphical user interface elements, the audio interface including audio inputs and audio outputs, the control circuitry of the TWS headphone charging case including one or more cellular data radio circuits and one or more application processors;

executing software application code for audio software applications hosted by the audio operating system; and

providing the software application code for use by the portable electronic accessory responsive to the audio inputs.

17. The method of claim 16 , wherein executing the software application code comprises executing the software application code by one or more cloud servers remote from the portable electronic accessory.

18. The method of claim 16 , wherein executing the software application code comprises executing the software application code by the one or more application processors of the portable electronic accessory.

19. The method of claim 16 , wherein providing the audio interface at the portable electronic accessory comprises:

providing the audio outputs to one or more speakers of one or more headphones of the portable electronic accessory; and

receiving the audio inputs by one or more microphones of the one or more headphones of the portable electronic accessory.

20. The method of claim 16 , wherein executing the software application code comprises coordinating activity of the portable electronic accessory with activities of one or more other portable electronic accessories.
