Isn't it obvious? It has a detachable cable with a mic. It seems to be made of "better material" such as the urethane cushion which can also be flip inside out....(if such thing appeals to you). It has a case thats not provided with xb800/900. Most of all its a "celebrity headphone" which equals more style and the "brand name". Both party will be getting paid so they will obviously have to make it pricier.
Thats all I can think of but yea if all those stuff does not matter to you then go for the xb800. Honestly just for those extra accessories it better to just get the xb800.
