I concur. I gave them both a try yesterday and they were much comfortable than the Momentum 2.0. Momentum feels like the cup is covering 3/4s of the ears. Speaking of sound quality, I personally think the QC35 is leaps and bounds ahead of the QC25. It sounds very clear and I would definitely go for the QC35 over the Sennheisers any day (and with the excellent noise cancelling feature, it becomes a no brainer).
