B & W CM5 S2 vs Usher BE-718

I have chance to buy a used pair of B & W CM5 for $800 and honestly I loved the sound. I was impressed however next month I will go to Taiwan and can pick up a pair of Usher Mini-X DMD for around $1100 dollars. They are much cheaper in Taiwan. However, I have never listened to the Usher’s. What do you guys think?
