What's missing from the existing ones?

There are other fast charging standards than Power Delivery. USB Battery Charging defines that when the data lines are shorted, a device can draw more current (up to 1.5A), but still at 5V. QuickCharge on the other hand uses the data lines to negotiate higher voltages, so an A-to-C cable can't protect you from that.
For Power Delivery, higher voltages are negotiated using the CC (configuration channel) pins. If you use an A-to-C cable, the A side does not have the CC pins and therefore you can't get more than 5V.
Have you checked what voltage arrives on the board if you use a regular USB-C charger? Maybe the headphones negotiate and need a higher voltage than 5V. Does it charge with only 5V supplied? (could be forced by using an A-to-C cable in case of Power Delivery)
That's what I've been using for a few years now, with SimpleCalendar (soon Fossify) on my phone. Didn't have any problems yet.

Das stimmt auch, freie Weichware darf natürlich kommerziell vertrieben werden. Aber die nullte Freiheit ist, dass eine solche Anwendung zu jedem Zweck eingesetzt werden darf. Es darf also kein Unterschied gemacht werden zwischen privatem und kommerziellem Einsatz, letzterer darf also nicht ausgeschlossen werden, das meinte ich.
Den Quellcode darf man übrigens genauso verkaufen wie die kompilierten Programme. Aber es gibt in der GPL ein paar Einschränkungen bezüglich des Preises den man verlangen darf, wenn man Kunden erst nur die Binärdatei ausgehändigt hat und die dann im Anschluss ihr Recht auf die Soße einfordern.
Der Krüppel kostet ganz bestimmt nichts für kommerziellen Gebrauch, das würde der Definition von Offener Soße/Freier Weichware widersprechen.
I've used it quite extensivly, big fan. It asks for further details on objects that have already been mapped, which also reveals things that don't exist anymore. It turns mapping into a really fun game with currently 163 different quests. The app also regularly asks you to verify opening hours or confirm the existence of certain objects. That being said, I almost always use it in conjunction with a real map editor, to add new stuff I find or to make more complex edits.
