There's definitely worse than the srh940, in term of comfort , having tried the hd25.
I find them very decent in term of comfort, I'm not sure why people are complaining.
Also modding them helps to increase comfort, although my main reason to mod them was desired sonical changes (you increase
depth of ear cup, using a rope).
Others suggestions:
beydynamics DT770 or DT880, (many pic from studios, where singer wear such headphones)
hd600 (producer steve hoffman like them, most neutral sennheiser headphone)
german maestro closed models (marketed for music production, and one of the best built quality you could find).
fostex t50p (marketed for music production, people that mod them swear it's an incredible sound for the price).
