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.
Compared to 3.5mm where the frustrations I remember were usually limited to sometimes getting a bit of a crackle or one of the audio channels dropping out and worst case scenario you just unplugged it and put it back in and it usually worked. With USBC you have to wait to see.
