Having a headphone jack will let you use any kind of headphone produced in the last 50 years, which has a 3.5mm jack. Also, while listening to music you could also charge your phone, if you choose to, but not with a USB-C only port. Furthermore, USB-C DACs are stupid, they are an annoyance, even the ones with the shortest cables - I broke three of them in two months because they’re idiotically designed and they don’t fold in my pocket - a thing that never happened with headphone cables.
