What kind of headphones/earbuds do you use, if at all?

I recently went through two pairs of Skullcandy. While giving pretty good sound quality for what I paid for them (NZ$80), they both crapped out. Luckily, both were within the same warranty. So for 8 months, I borrowed two pairs of headphones (which they will not be able to re-sell), for an $80 bond. Mucho gracias, amigo.

But I'm not going back to those. I'm getting something a little better. Not extravagantly better (though that would be awesome). But I've decided I want something with a closed-ear (I like how it feels and looks, and is better for the health of your ears, while providing some filter for outside noise (meaning your music is clearer, and you don't need it so loud)), but also collapsable (foldable... whatever the term is), so I can put them in my pocket or in my bag, as I only use headphones when out and about.

Talking to friends, looking in shops, and mulling over the Internet, I'm currently favouring these.

What do you think?

And what headphones do you use? Have you put much thought into your decision, or do you just stick by the trusty 'phones that came with your device?
