Looking to upgrade from my Ultrasone 680s.  I love the sound but they aren't really comfortable.  They start to hurt around my ears after listening for an hour.  Need something I can have long listening sessions with.  I would prefer something that has a sound similar to these.  I was wanting to buy the Ultrasone Pro 900s but they look the same as the 680s, just with felt ear covers.  Can anyone recommend me a good pair?  
 
I want them to be a closed headphone and I am willing to spend $300...or maybe a little more for the right pair.

The 680's appear to similarly designed to the HiFi 780.  If that is true, the Pro 750, 900 & HiFi 2400 (open) will each provide a major step up in comfort.  If you are a basshead and have the money, so for the Pro 900.  If you want a more balanced "wall of sound" with solid bass and slam, get one of the the other two.  Regardless of what you select, you will need to amp them.
