My g430 headphones recently broke and I narrowed it down to the wire that connects the left speaker to the right. The video I was watching recommends using a spare RCA cable to replace the wire, my only problem is that every wire in the headphones is aluminum but the RCA I took apart is copper. I understand that connecting them directly would be stupid but the connection would be going through the little PCB (image) they have in the headphones. Would this still be safe and durable? I don't know much if anything about electronics I just have a soldering iron and youtube.
