From personal experience, headphone jacks have been more susceptible to wearing out than USB-C.
The connection became so loose that the plug would slip out on its own.
The jack would (I assume) partially lose contact, resulting in missing frequencies in the audio and crackling if I rotate the plug.
Both of these can be partially remedied by cleaning the port, but after six years with my old phone even that didn’t work anymore. The USB-C port still did, however.
