Left ear not working/connection problem

Hello! I have been using pre-packaged earphones with my iPhone XR for 1.5 years now, and recently they started glitching. After somewhat thorough inspection I concluded, that it is the lightning port (not the hole in the phone, I mean) that is causing trouble. Is there a way for me to replace the port? Maybe cut one from one of the old cables and solder all the wires? Is that even possible/worth trying?
