I love my HD555 heaphones too. Fortunately, I work from home, so there's no one to annoy with the sound bleed. Generally speaking, I won't recommend Bose equipment because of the poor cost/quality ratio, but their sound cancelling headphones actually work really well for their intended purpose. I've not used a set that works better, although I think they do some kind of funky sound enhnacement, because some music just sounds strange when using them. Regardless, I consider their primary function drowning out background noise (like on a plane), and in that regard, they're unbeatable.
