Headphones for playing a live tourney

[djack]

What headphones are best for filtering out the noise of a live tourney? I may listen to music at some points during the tourney, but mostly I won't be. I'm posting this here, but maybe I should post it in MTT.

I'd prefer not to spend much because I'm cheap, so value is important.

Are headphones better than earplugs? I prefer headphones to earplugs anyway, so it's not that much of an issue, but I'm curious as to whether and how much I'm giving up with headphones instead of earplugs?
