ok i'll explain a little better..some time back i fixed it by soldering wires ..the wires got really small near the usb plug so it was very difficult to solder it back again.so i opened up the usb plug hoping to find space to resolder the wires but they were sealed in rubber , so i thought i have old mouse i cut its usb wire ..there are 5 wires coming out of head phone one of which is shield wire whatever that is , its in pic u sent.from first to last is as follow red , yellow (gold) , green , blue..thats the combination in volume control area when i open it. now the mouse has these wires green , red , white and yellow doesn't have shield wire
