Sony MDR-XB450AP Extra Bass Headphone - Blue (International Version U.S. warranty may not apply)

hey what's going on guys so today I've got the MDR XD for 50 AP this is a stereo headphones from Sony and this one has the inbuilt microphone so you can see over here it's got it says that hands-free for phone calls and works with Android iPad iPod iPhone and Blackberry phones and I've actually tested this before and does work with Windows Phone also now these particular headphones come in like two variants so one of them is MDR xD 450 which is this one this is the one which I currently use and you can see the model number over there MDR XP 450 and the difference between these two is this one supports hands-free so this one will have a microphone on the cable and a little button so you can use it for your hands-free phone calls so keep in mind guys the XP 450 ap has that hands-free feature and this one does not I actually did get confused in both of these so first off I ended up purchas
