Bass orientated portable headphones for up to £200

As the title says, what are the best basehead portable headphones for up to £200 (high 200 dollar wise) in your opinion?
 
I've had a look at the M100 so far but they look a bit strange.

From my personal experience the Ultrasone Pro900 is the top basshead phone at any price. Can be found used for less than $300.
