I, for one, am comfortable with the standard pads and never bought the XL pads. Plus I like the look better with standard pads...
Yes, they sit on my ears in part, but I found a position that is comfortable for as long as I do wear them (which is 2-3h max as I use other headphones at home / at the office).
As I understand they are sold at about no win / no loss level as they are much more complicated to make than the standard pads. Its nice that they are on offer for people who are having problems with comfort, but reading reviews most seem to be fine with the standard pads I think.
There was a revision of the so called over-ear Momentum? They were a nightmare for me btw., too small by far.
I agree that the standard ones look better. I think a large majority of people have no issue with the standard pads. It sounds like you're not 100% without problems. I can't use them at all.
The Momentum revision is mentioned here:
