Let’s begin, predictably, with an Apple product video. The ad opens on a dark screen, pebbled with stars. As the music swells, our vision pans over a backlit curve — a planet, presumably, as depicted in just about every cinematic space opera — and then the curve reveals itself as a human head, cradled by a large set of headphones. AirPods Max have arrived, unruly product name and all. (They cost $550, and so far the reviews are mixed.)
