I am looking for a pair of excellent portable over the ear headphones for use. I would like my iPod to be able to drive them sufficiently, and would also like minimum sound leakage. Thus far I have thought about the Beyerdynamic T5P or the Audio Technica W5000. And when I say portable, I mean that I could wear them on the airplane or occasionally out and about. What are your opinions on those and do you have any other suggestions?

I don't have experience with the two you mentioned, but be sure to check out the Ultrasone Signature Pro. Fantastic sound, highly isolating, and very portable.

Do you mean the Edition 8 or the S-900's? From Ultrasone?
