I share the same hope that this will give our hobby a fillip and will make high-end headphones more popular. The marketing blurbs are clearly trying to entice consumers with the promise of a hi-fi experience (note the third quote, below, re. floor-standing speakers). This arguably goes beyond the usual tech/specs spiel that Apple uses to appeal to customers.
From the product page:
From deep, rich bass to accurate mids and crisp, clean highs, you’ll hear every note with a new sense of clarity
The Apple-designed dynamic driver produces a wide frequency range that uncovers the rich details of every sound — delivering your favorite songs with previously unheard texture and accuracy
Modeled after those in high-end floor-standing speakers, the driver’s dual-neodymium ring magnet motor minimizes total harmonic distortion across the entire audible range. The result is consistently clear playback, even at full volume.
Alas, all of the above came after the marketing about the headband, color scheme, and the “digital crown.” But this in the press release further speaks to the desire to promote ‘hi-fi’ sound:
A unique dual neodymium ring magnet motor allows AirPods Max to maintain total harmonic distortion of less than 1 percent across the entire audible range, even at maximum volume.
