I don't know exactly what you have, but there is a common form of very flexible wire used 
for headsets that has fine copper strands mixed with some fibrous material. It might help 
to put a little liquid flux like the stuff that's used for SMT work on the wire. I've 
tinned this stuff by passing it through a gob of solder on my iron, sort of the way you 
tin toroid leads. Sometimes you can separate the copper from the fibers with your fingers 
before tinning it.

If it's not copper, you may be out of luck and you will have to use a plug that has screws 
or some form of mechanical connection.
