For headphone use I'm against switching over to USB-C because it doesn't have the serviceability of a 3.5mm jack, I still own 3 sets of 3.5mm earbuds that I use everyday and the selection of USB-C type headphones is somewhat limited. Imagine soldering on a USB-C jack. It would be trickier than a 3.5mm jack. Does USB-C provide better structural integrity with the PCB it is soldered to versus a 3.5mm jack? Linux Tech Tips tested a USB-C to ~8000 insertions and and disconnections and it never failed. I doubt a 3.5mm jack would withstand this before the locking spring and conductor springs stretched or broke inside the female jack and the PCB copper traces broke or the solder joints broke. Who is for USB-C and who's for 3.5mm?
