Which headphones are comfortable?

I listen to Grado sr-125s for 4-5 hours a day at work through my ipod, I have found them to surpass my expectations for comfort and sonics.

Sennheiser - nothing else will do!

Sennheiser 600's. I used to have some really nice ByerDynamics but they were just uncomfortable so I never listened to them. The Sennheisers not only sound incredible, but they are very comfy..

Sennheiser and tubes are a good substitute for sleeping pills.

I'm kidding (sort of) I have Senn 600 - and Grado RS-1. I have tube amp with Senns (ASL MGhead) and RA-1 for Grado. I read all the hype about the Senns and they sound great for classical. I like the Grado for rock and jazz (actually Senns are good for jazz also). The Grado's are just more musical and toe tapping. They both have a place in my system depending on the music. I would miss either one if they were gone.

Oh, comfort... ummm the Senns are much more comfortable.

Don't even try the in ear canal phones - I have the Shure E3 and I'd rather stick an icepick in my ear.

Thanks for all the info. The Sennheiser 580s and Grado SR-125s were topping my list and this info reinforces my thoughts.
