From what I've read the X5's are a tad bit bigger and more balanced than the X10's which are supposed to be more bass oriented. I would say if you're looking for something with better bass, go with the X10's - and if you want a more balanced sound go for the X5's. Keep in mind I haven't heard them though, this is just what I remember reading from previous comparisons I have seen on the site.

can you elaborate on why x5's are your choice? there are many who would like to know
