Did USB-c match their needs?
I can't imagine it wouldn't. The USB-PD spec can cover a verity of voltage and amperage combinations covering practically any digital electronic device up to 100W.
The only reason it's not used everywhere, is that it does add complexity to extremely simple and inexpensive devices. This thing is not simple or inexpensive, and it doesn't draw more than 100W.
That's not really true - it maxes out at 5 Amps which is only a decent amount of power if you use (relatively) high voltages. Vision Pro runs at 13 volts, which isn't supported by USB and if it was that would only be 65 watts - nowhere near enough to power this product.
Running at higher voltages (USB can do up to 48 volts) would likely have problems, it might be less efficient for example (which would mean they have to give it a larger battery).
I'd be surprised if the headset even drew 65W, the other points notwithstanding
