USB-C headphones and DACs do exist too.

> The only other solution I have found is a USB-C-to-3.5mm dongle but then the phone doesn't fit comfortably in my pocket anymore, and it's very inconvenient when running.

Get USB-C headphones rather than a DAC so that the DAC is in the headphones. There are high quality ones including earbuds.

I would gladly pay you generous reward if you can find a pair that fits me.

I literally mean this.
