I'm talking about this specific context, rather than in general. I find that for usb-c earphones and small dongles/dacs, they disconnect more when I'm walking around with phone in pocket. They also tend to wear down with use much faster than normal aux cables. Usually, they last a few months for me before I start having issues.
And when usb-c phones disconnect just a little, usually the phone will pause the music completely and disconnect, whereas the aux headphones will just keep playing. So if the connection isn't perfect, the usb-c cable becomes unlistenable because I can't walk 20 steps without it pausing.
edit: I've tried many cables and dongles, so if you don't have this problem, it might be just that I move around more? Biggest problem for me is commutes and walking around.
