its the htc headset,its wired and it plugs into the micro-USB port instead of the headphone jack (digital sound vs analog sound) they came with my TP when i first got it but back then the audiopara exchange worked right away so i dont know what the difference is. i would get some noise cancelling ones if i can find some that are digital (uses the micro USB port). and calls can also be answered with it.
