It's likely some variant of "Litz Wire" which was commonly used in cloth covered headphone wires 2 or 3 hundred years ago [I'm not older than dirt, but I CAN remember when dirt was young :-) ]. Several very thin, flexible strips of metallic conductors wrapped around a thin string or two. Virtually impossible to solder and the metallic strips may not be Cu but some alloy. Connections were made mechanically by crimping to pins and lugs.
You might be able to crimp on a very small pin [like a Molex pin] which will take solder and then solder that to the connector. 73, Fred K6DGW Auburn CA USA > Bob DeHaney wrote: >> I bought a Sennheiser Headset to use with my K3, and the stereo headset >> audio plug is defective.
