Personally, the Audeze headphones (specifically the LCD-X) doesn't make the top 10. Not a hater, just the way I feel. Some headphones off the top of my head that are supremely comfortable that I've worn (some haven't owned) include:
HD600/650 - actually most of the older Senn's (HD555/558/598...)
The most comfortable headphone I've worn is the Beyerdynamic DT990 but all the Beyer headphones are extremely comfortable IMO.
The Fostex are lightweight and the Beyers will never cause you any pain whilst they're on your head, but they both have their drawbacks. The Fostex pads are too small and the Beyers (T1) have a horrible spike that causes your ears to ring for hours after you're done wearing them.
I'm not in any deliberate way trying to be contrary here - I genuinely believe that Audeze and Hifiman make some of the most comfortable headphones. I had zero problems with the HE-500 and the minor comfort-related issues I had with the Audezes were rectified with a little tweaking.
Having said all of that, I can perfectly understand that not everyone will agree.
