so I kept getting my feet wrapped in my AKG K550 headphone cord and finally I had a problem with a connection. I re-soldered the wires and just couldn't find the problem. Finally I found that the wire that looped to the other ear was broken at one connection to a thin copper ribbon cable. It couldn't be repaired as there was no room. The ribbon cable slips inside a flat channel that covers it so the sliding headphone adjustments wont wear on it. I tried using a piece of expensive flat speaker cable made for slipping under rugs. It just about fit. I guess I could have flattened it in a machine vise but didn't think of that until now.
Anyway, here's the picture of the flat cable needed. It is about a foot long with two solder pads. I can double it back and make the pads if I can find the cable. It's really thin, probably .010" and I'll measure that thickness if needed.
I called AKG and they only sell accessories. I can see why because reconditioned units are only around $100 now, about half what I paid for them on sale years ago. I probably have half that in the speaker wire I used. I looped the speaker wire outside the channels for now. They are decent phones and I recently replaced the ear pads. So yes, I know I should pitch them it's just that I've grown accustomed to their sound. I have other phones, bose, etc noise canceling types that hiss a lot and I have to have a wired connection to my keyboards.
Anyway, I've looked around for the ribbon cable. Any ideas?
Thanks,
Jerry
