Just buy any audio cable (multimedia stereo cable having 3.5mm jacks on both side having suitable length) from any common electronics shop near you, then move to any electronics technician in market (preferably the one who is repairing
tape recorders, tvs, speakers etc), ask him to cut this cables one end and join with the port inside headphones from where the cable jack part is coming out, ask him to remain the actual connections of headphones with connecting this wire on its inside electronics terminals then just cover back your headphones, its only a 5 minute job and very easy. tell him the headphones wire issue and he will attach this new wire inside headphones terminals then these will be okay,
Best of luck
