At first I was also obsessed with a 3.5mm audio jack, then I bought a phone with only USB-C, and guess what, a simple adapter that was in the box, or available for $1 in dollar store, basically does the job. The USB-C plug has 4 wires for gnd/left/right/mic and I can plug any 3.5mm headset on my phone. The adapter is on my headphone for months and it makes no difference me plugging an audio jack or a usb-c plug.
