If we're talking Bond-tier assessments then Apple already sell a covert microphone: AirTags. They “have no microphone” according to product specs, but they do have a huge speaker, and a speaker and microphone are the same thing like a generator and motor are the same thing: https://in.bgu.ac.il/en/Pages/news/eaves_dropping.aspx

Just because a speaker can technically operate as a microphone doesn’t mean that AirTags would be capable of this. The speaker driver definitely doesn’t have any recording capability. The only reason the 3.5mm jack mentioned in your article is capable of this is because the jack has functionality to allow analog recording for mic/line in cases. No dedicated speaker driver would have this because it would be worthless and costly.

There’s a fairly large jump between having a microphone and being able to be used as a surveillance device.
