it be a cable . it be quite long . it work . I buy my husband a set of wireless headphone to use with he xbox 360 for he birthday . unfortunately , the cable that we have for the xbox -lrb- a gift , receive without a box and probably use -rrb- do not have the correct port for the audio connection need for the headphone . this cable have the correct port and arrive quickly -lrb- and cheaply ! -rrb- . no brainer if you xbox come with the older version of this cable and you need the extra connection .
