Looking to buy headphones

I'm looking at getting a pair of full sized, noise isolating headphones for listening to my iPod on the go.  The headphones would need to be at least kind of portable, cheapish (about $130 CDN max), and sound good.  I have no idea where to start, though.  I really need some advice.  Thanks in advance.

Koss portapro. Genious. Have a pair myself, and not only is it portable, comes in an own small, leather bag, and have an adapter to Guitar jack: It's got a lifetime warranty! Here in Norway, it costs around, well, lets see, about 30 euro, about 50 Canadian Dollars. Thats what it costs in my country.

You want cans for on teh go?

I roll with in-ear earbuds.

I guess the boss soundports are good for portable cans. dunno bout the pice.

Yeah, I want to have full sized headphones since I want good sound quality and isolation.  I've never had a pair of in-ear earbuds that have fit in my ears really well.

Steelseries Siberia?
They don't have noise isolation but they look SICK and haven't heard anything bad about them.

I'd link but Steelseries' site is down.

Actually, get these: http://www.sennheiser.com/sennheiser/home_en.nsf/root/private_headphones_audiophile-headphones_500319

Oh, god, I want those Sennheisers.  Most are a good ways out of my price range, though.  Some of their lower end stuff might be ok....

afaik senn doesnt make cheap closed (isolating) cans.

The ones that nullname posted are open cans (not isolating) and will leak audio like a motherfucker which is not good if you are using these on the go.

AudioTechnia makes some noise-isolating cans. AND they're active noise-cancelling, Buick recommened these to me when I was using a desktop mic.
