Seenheiser 414 or 424. Smaller ones are light and more comfy. For uncomfortable ones, try lessening the tension they impose on the ears, by bending the top band - becomes more comfortable.
Headphone I can stand for more than 1 hour
Every headphone I have ever had starts to drive me crazy after 1 hour. I started with the Sennheiser HD 414. Warm foam cushions and push too much on my ears. Tried the AKG K-1000. Too heavy and push on the side of my head. Grado SR 325 - too warm. Why can't anyone make a headphone that sounds good and one I can use for a couple of hours? Have you found a comfortable one yet?
