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.

Up to 240W now actually

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’ve heard that argument floating around and I don’t buy it. Step-up and down converters are a thing.

That’s a terrible argument. Apple could have very easily made this run at something other than 13v.

I’d be surprised if the headset even drew 65W, the other points notwithstanding

Yes, and apple did choose not to, so their customers will praise apple that they got ANOTHER only apple connector!

Not to mention the praise for “innovation”. I swear to God most of the “innovation” I see is more proprietary or useless shit to screw over the customer. I suppose regarding company priorities that’s excellent innovation.
