Could not agree more. No-frills styling (i.e. kinda fug but durable plastic), extremely comfortable for long periods of time, over-ear doesn't leak a lot of sound into your surroundings, nice low-end punch, and otherwise flat enough for basic multitrack mixing work.
While I agree on all of the other points, they are most definitely not extremely comfortable. Especially if you have a larger head, you'll feel like your skull is in a clamp quite fast.
Other than that (and the headband cracking) those are one of the best headphones I've ever had.
I wrote it in May. It was well received then, but it has gotten more play now since the 37 signals post on caching. IMO my guide is the definitive guide to the caching system in Rails.
I believe this is the first time it has made it to HN. I've always gotten very good feedback on it. Thanks for your comments.
