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.

Edit: Gotta love the downvotes without any actual counter arguments. Just because you don’t like my experience that doesn’t make it invalid.
