With all this discussion about earbuds, I feel I should pass along a (possibly overcautious) warning from the Safety person where I work. I'd off-handedly mentioned that I'd just use my noise-cancelling headphones in the server room, and he was fairly insistent on verifying that they had a rated Noise Reduction Rating, as apparently just cancelling background noise isn't enough. So, right now I use foamies with a 32 or 34 NRR, and forego the headphones, since I couldn't find adequate documentation. Might want to consider similar, or at least consult someone more familiar with safety before forging ahead.
