USB-C is far easier to break than rca plugs in my experience and then you lose data and rapid charging or charging completely if the phone doesn't do wireless. Until phones get repairable like the current generation of laptops where you pop the port out and can replace it we aren't in a great spot.
It's annoying. Especially if you use those headphones on another device that has 3.5mm headphone jack and no easily accessible free USB C port. And if you need to charge and use headphones...
You can even keep the connector on the end of the audio cable permanently.
