Ok for this step plug the jack into its place(pink audio slot). After that click Start>Programs>Accessories>Entertainment>Sound Recorder. It will open up a box, when holding one of the headphones up to your mouth click the red circle and say something like "Test Test, This is a Test" now press the square to stop recording and then press the forward arrow to play. If you hear your recording then the headphone you tried first is the microphone is not click File>New when it asks to save click no and test with the other earbud, keep track of which is which otherwise you will mess up ruin your microphone and waste a set of perfectly good headphones.
someone help!!
