I'd like to add to the chorus of endorsements for noise-cancelling
headphones! A few years ago, I used to spend very, very long hours
in a large datacenter. The constant noise was really getting to me.
I bought a pair of Sony MDR-NC20s (discontinued, now MDR-NC50) and
they made life in the datacenter MUCH nicer.

I agree with below that over-the-ear not only does a better job of
sealing off noise, but keeps your ears warmer as well. I find that
my ears need to adjust to new headphones. Wearing them for long
periods of time will hurt initially, but that goes away.
