Reddit reviews Electrovision 3 5mm Stereo Jack Plug, Gold

but then it is much better for the environment and you don't have to inhale lead fumes. Personally I'd recommend replacing the plug, as long as you have a fairly steady hand those 3.5mm jacks aren't too hard to solder. It's probably easier to replace it by cutting off another jack and splicing the cables, though you might have a bit of a tough time identifying which one is which. You'll get a neater job by using something like this though.
