Chosen Solution
I have a pair of Beats mixr headphones with the aux cable soldered straight to the speaker (don’t know why). A wire from the wider cable and a wire from the aux cable have deattached and I would like to see a tear down to see where to re-solder the wires onto the speaker. I can’t take out the Monster cable (it’s actually a genuine cable), and one ear works. The other ear has another aux port. When I use another aux cable, the ear that doesn’t work with the other cable works, but not the one that worked last time. So I have to use a headphone splitter and plug in both cables for both ears to work. But that’s a pain. How would I re-solder the deattached wires? An image of the disconnected wires is below.
@dudeperson use a multimeter and see if you have continuity between point 3 and 4. Measure between 1 and 3 and 2 and 3 and make sure that you do not have continuity. If those points are true you can solder the ground wire to point 3 or just solder it above or with the ground wire (green arrows) coming from the input cable.
