Still no headphone jack makes this a nonstarter, lame.
How often are you listening to music on your phone while it's charging? (because otherwise you can always just attach an adapter onto your headphones to make it USB-C). Seems like a weird hang up.
First, that's almost all the time for me because my primary use case for listening to music is in the car. Second, adapters are not a good solution because they can easily be lost.
