[vedant.naik09]

I just broke my headphone plug.I bought a new one from the store.Just split the wires and found a blue,red,green,copper and red and blue wires.Where should i connect these??

easiest way is to use a multi-meter at the broken plug, the kind that beep for continuity make it quick and painless - just touch the probe to one of the bare wires and the other to the TRS plug and you will know which ones go where. Good reference on earbud repair here.
