USB cable torn out wires exposed? Repair?

ok these wires are insulated... This means you need to solder them back together.. there is a single wire inside each color.. twisting them will simply make matters worse.. I would cut them so there is a even wire that is not frayed and solder the ends back together.. this will work you just need to get a solder gun.. If u dont have one they are like 10 15 bucks at walmart..

wires are copper, red, green, copper wrapped in red, and copper wrapped in green. Sometimes blue....5 wires... do not untwist the 2 wires that are wrapped in copper.. they are supposed to be like that.. Im having trouble fixing my X11.. the wires inside the headset part came undone and I don't know where each wire goes on the circut board... NO ONE KNOWS... I have been looking forever and thought I might as well help someone else..
