This misses the point.
EVERY device I carry with me charges via USB-C right now.
My laptop, my work laptop, my headphones, my phone, my tablet/e-reader (remarkable).
It's insanely liberating to know that I can pretty much always find a charger for everything, and I only ever need to pack a single wall-wart.
Flying? One charger. Road trip? One charger. Biking to work? One charger.
Better yet - Leave a charger at work, keep a charger at home, don't need to carry 5lbs back and forth every day.
Forgot my charger? Every person I hang out with has a usb-c charger floating around somewhere.

You know what I really don't want to have to carry around anymore? Fucking cable adapters. You know what no one will have if I forget my charger? Fucking cable adapters.
Honestly - I probably wouldn't have bought these headphones yet because I'm quite happy with my current headphones.
But I'm very, very close to no longer even considering devices that ship without a USB-C port. And that's a shame, because I otherwise really like the Max, and probably would have slotted it in when my current cans die.
Getting over the hump to convert to USB-C initially was fairly expensive, but my job is good and I can splurge. I don't want to go back.
