I find the Sennacherib to be very comfortable but I haven't tried em out in years. That's Sennheiser, but I thought the word was funny as this is what spell check came up with lol.
I tried Grado's, loved the sound but not that comfortable. I also tried some HUGE AKG headphones and found the fit unappealing. Even with the comfort doughnuts. I'm in the market for a set of cans but it's low priority. I have my own small room downstairs away from the upstairs bedrooms, and I listen to mostly quiet music, quietly.
