Actually, IMHO, if the bolded the criteria then the MDR-1R would win out. They feel more comfortable and secure over the head than the Momentums and the MDR-1Rs are true circumaural. I'd grant the Momentums to be more "common hi-fi" sound with it's somewhat U-shaped signature.
It really depends on the shape of your head. For me, the Sony felt much less comfortable and secure than the Momentum. They're also lighter than the MDR-1R. The Senn is one of the most comfie portable cans I've ever worn.
