Then using a pencil eraser, preferably an old pink type eraser, carefully clean all the surface areas as best you can then wipe with a clean & dry paper towel or lint-free cloth.
Some may not make contact as well due the the size of the contact area (tab inside jack) or the amount of force holding the contacts against the plug.Ĭould you carefully inspect the non-functional headphone plug (preferably with a magnifying glass, unless your closeup vision is better than mine) to see that there's no discolorations or imperfections on any of the surfaces?
I'd definitely be suspicious of anything 'gold plated' in this day and age.Īlso, all jacks are not the same in how they make contact with the plug surface. So, we're talking about the standard 3.5mm stereo (4 conductor) plugs, right? The only difference between them that the one that doesn't work is gold plated.
One works, the other one doesn't but both work in the front panel jack.
