Chico's review compares the annies directly to the X1's IIRC. I love the annies, but currently you can get the akg k712 pro for cheaper. Also keep in mind that you cannot service the X1's pads. So if they get damaged you are sol.
Have you considered the sony ma900? I have demo'd these and they are outstanding. For 200 bucks you cant go wrong here at all.
