How do engineers squeeze all the necessary circuitry (and what is it?) into one of these devices, and do so this inexpensively?

With the demise of analog audio line out, headphone (output-only), and headset (adding mic-in) jacks in modern electronics devices—computers, smartphones, tablets, and the like—alternative methods of connecting analog audio sources and destinations are becoming increasingly common. Bluetooth-based wireless mating is certainly one option

The other common option involves instead leveraging the digital audio (plus power, along with other functions) connections that are still present in these devices.

Now that Apple has transitioned its devices to USB-C, both it and Google, along with others, offer(ed, in Google’s case) diminutive, cost-effective, and performant USB-C-based successors

And…whaddya know…for a pleasant change, the C-Media CM3271 USB audio controller shown in the earlier conceptual diagram actually matches what’s on the PCB underside!

Otherwise a 20ms delay is perfectly acceptable and error correction is worthwhile. Dante’s forward error correction seems the best bet to me.
