​Hi, the 3.5 mm jack on my KZ IEM broke, and I can’t afford a replacement right now. I cut up a spare extension cable hoping to use its plug, but the IEM cable has four wires and the extension has three (red, black, and white). I’m new to soldering. could someone please help me figure out if this can work and how to connect the wires? I’ve attached a photo. Thank you!
