EXTERNAL SPLITTING:when its connected to the external devices like DJ-turn table,mastering amplifiers boards,if yo wanna use only only the mic for backstage.
just disconnect the mic from the damaged headphones(use anthing this to split but tak concern of the wire not to be damaged) and you will be getting a wire along when you disconnect,so get that wire along don ever touch that,apart from that you will have the wires run to your headphones,just cut that and wound it with the cellophone tape,make them not to touch each other while playing,because you will get some loss.
