I know nothing beats a good pair of reference speakers, but there are headphones out there that are labelled as "suitable for mastering." Anybody use these? Can anybody recommend a decent set? I'd quite like to have some reference speakers, but I don't want to drive the neighbors crazy (I live in a 4 unit apt. building). And I'm realizing that while I can get a nice-sounding mix through my plain old stereo, it won't sound that way through the iPod or in the car...at all... anyway, comments/suggestions?
