I mentioned AKGs for home listening before but forgot the model #. I use the K501s. They require a headphone amp, but sound great. They're a little light on bass, but I'm not a bass hound, anyway. Open headphone, nice natural sound.
I didn't go for the Grados or some of the others mentioned because they're supra-aural (pads sit on the ear) and I wanted circumaural (pads sit around the ear, not on it). I go absolutely bonkers with supra-aural headphones, regardless of sound quality. Sensitive ears, I guess.
Anyway...I also have the Sony 7506 for work, and they're okay, not great. And I love my Etymotic ER6s for field use and on my motorcycle.
