Earbud Recommendations

Calling all audiophiles (this includes you Adrea), do you have a preference in brand and style of earbuds? Anything with noise cancellation that's not going to break the bank?

I listen to my Muvo everyday while at work and the earbuds supplied by Creative do a decent job sound-wise, but I need noise cancellation as well. The equipment in my area interferes with the noise quality and I don't desire to continue increasing the volume. I'd like to have good hearing for years to come. Hence, my search for new earbuds.
