If they want to get these things into schools it would be insane to expect the schools to also supply everyone with AirPods or some other kind of wireless headphones.
... Only a few people make music with a Mac, but it's been an important part of its history, and Apple cares about it.
This seems to be a recent phenomenon. A lot of electronic music production uses the Macintosh and Logic/Ableton workflow, to say nothing about how many of the best DSPs were Apple-exclusive until about a decade ago. I don't really think music production, at least in the EDM and hip-hop world, got popular on the PC until the rise of Fruity Loops and FL Studio, but that's available on the Mac now too.
