I have upgraded to USB-C headphones...
But, years ago I got a handful of USB-C to 3.5mm adapters as manufacturers were starting to discontinue the 3.5mm jacks by default.
I was of course used to needing a USB adapter for headphones because I had a RAZR v3 for many years, which I also used as an mp3 player. I believe it only had a micro USB port.
