I went for the "Velour" option from Sennheiser in the end... just seemed like they'd be the more comfortable option..   BOY do the EVER make a difference.   Comfort wise - it's like wearing a much more expensive set - they sit snug, but not unpleasantly so.. even after wearing them an hour...

I've had a set of capitals for a couple of months - I love the sound and the simple construction. The slight "clamp" and sound leakage make them perfect for running.. because of the larger drivers they have much meatier sound that most in ear type headphones - and in ear ones (wireless or not)...
