Headphone Repair Question
 

Am trying to repair the (cat chewed) wires of my new titanium headphones,
and the usual splicing is not working. They are full size, the wire going to
a 1/8 jack. I can undo my repair and hear a low voltage from my supply
when applied to the wires. There are a common and either green or red wire
on each side, they do not seem to be insulated from one another (the common
and colored wire I mean). Any ideas as to what I am missing are
appreciated. :)
