Also I think the more serious issue is the SD card slot. The missing headphone jack is annoying, but you can work around it with an adapter. Not so for the card slot
You can work around the SD card just as "easily" as you can work around the card slot, as you can just always keep a usb-c sd card reader plugged into the phone.
Obviously, both of them are absolutely silly "solutions" to problems that wouldn't have been necessary in the first place.
It is an insurmountable hassle as none of my other devices — cameras, beltpacks, intercoms, mixing consoles — use or support usb-audio, nor will they ever.
It's already enough of a hassle to add/remove the 3.5mm/6.35mm headphone adapter, I don't need to have another adapter I can lose.
Aside from that, the whole usb-c stuff is so much more sensitive to dust and dirt, I wouldn't even want to have a usb-c adapter on my headphones.
While I currently buy Sony phones, for a while I had a phone without 3.5mm port and ended up just supergluing a splitter cable & headphone adapter to the back of it. But you have to replace it regularly as even with a right-angle usb-c connector the twist and turn is too tight to survive more than a few months.
