My headphone has a faulty jack, it has sound only coming out of the right earbud. If the plug and cord is twisted/tangled right, there's sound on both earbuds, but that's occasional. Seems like I can just buy a new jack for my Skullcandy Ink'd earbuds, but I don't have a solder. Is there a store that can solder my new jack? Or do I just have to borrow it from someone? I live in Edmonton, Canada.
