I completely agree with this.
As far as comfort...both are really comfortable, but I feel the F1 headband mechanism makes it easier to get a good fit right away. With the MA900, my ears are always touching the drivers...with the F1, my ears are like a millimeter away from the drivers. This is really a case of YMMV.
