My headphones all of a sudden stopped working in one ear, then both. Same old story, I cut open the plug saw 5 wires (it's a TRRS plug, mic and button + headphones). The wires are
- Red (Right Of course)
- Blue (Left of course)
- Golden (ground of course)
- Green (no clue)
- Golden and Blue twisted together (no clue)
Plugging in the headphones to my laptop (which has a combo 3.5mm jack) I can hear sound on both earcups, but the sound is extremely low. My soldering is pretty shabby, so I'm suspecting that my bad soldering has increased the resistance so much that sound is low, but I'm not sure.
Why is the volume so low and how may I fix it?
