My cousin works at a major department store. Walmart. He works in the electronics section, and from time to time, people attempt to steal things by cutting the cables and so on. Anyway last week a customer tried to steal a pair of Sony ch700n Bluetooth – noise cancelling headphones, and the customer got caught. My cousins manager gave him the cans, but the only problem is that there is no jack, and wrt the cable itself., Well I'm used to seeing only right/left/common. These have two "regular" (PVC jacketed, pink and white) wires and 3 enamel coated wires(these are thinner than the PVC wires) colored green, gold, and red Presumably the enamel wires are for the mic and noise cancelling circuit? But tbh I am totally fine with skipping the mic, noise cancelling stuff and just using them as regular cans. My question(s)
1.) Which wires do I need *just for using them as headphones*
2) which of those wires is right and which is left?
3) is there a ground?
4) most reliable way to Remove enamel ?
Thank yall
If you have a multimeter, put the phones on, set meter to resistance as low as possible and try to find two wires that have some resistance to each other. If you are lucky there may be a click from one phone.

Enamel wire I have always scraped clean with a craft knife but if its very fine this may be difficult.
Seems more likely the enamel wires are the audio ones, and the others power.
But the wiring (if it's a demo set) may not be going directly to the drivers, it may be going to an internal amplifier.
Easiest way to remove the enamel so you can measure the resistance is to tin the ends (add some solder with a soldering iron) - the heat and flux will remove the enamel.

Fine emery paper can remove enamel from fine wires, repeatedly draw along the wire.
Many wire coatings are proof against standard soldering temperatures, requires higher temp setting, some give off cyanide fumes when burnt too, so ventilate well.
