Which Headphones?

[AppleSF]

Ok now I am in sort of a delema. I have found four headphones that I like the best coming from a list of ten I had. Now those four are:

Sennheiser HD595's
Sennheiser HD580's
Beyerdynamic DT 880's
Ultrasone HFI-650's

I will mainly be using these on my G4 20GB Ipod and on my computer for listenting to music or playing games.

So what do you guys recommend?

THANKS!

The HFI-650 as it'll be the most effectively powered by both sources. It also sounds pretty good.
