    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. :)

    Its called tinsel-wire. The stuff is made from thin strands of enamelled
    copper wire mixed with cotton? strands. Quite difficult to solder, it's
    meant to be crimped.

    Cords which have to handle a lot of flexing are sometimes made using it,
    usually curly telephone cords, and in your case headphone cords.

    Dave the wire in these cords are sometimes enamel coated for insulation,
    they put different colour to enamel on to identify. this enamel coating is
    very thin but tough to remove sometimes a bit of cooking with a soldering
    iron necessary, sometimes burning off with a cig lighter then soldering, or
    at extremes very fine sand paper before soldering or a combination of all
    three. the wire is very thin and delicate, good luck. or get a replacement
    cord from the manufacture. regards bob
  4. Hint for removing enamel:
    - Heat it up with a match or cigarette lighter;
    - When hot, quickly sink it in alcohol.
    The enamel cracks. Just take it off with your fingers.

    Thank you all, and to Ricardo, that worked perfectly and my head phones work
    great now.

    X-No-Archive: Yes
    By far, the most effective method for removing even the toughest enamel is
    dipping the wire in molten sodium hydroxide. It is probably the only effective
    way of removing enamel from a stranded wire made of enameled wires.
