I've got a pair of ATH-M40x that I use when I'm recording vocals with... I don't find them to be too "bassy" but I've only got a bunch of "consumer" headphones to compare them with, all of which have more bass. I've since "upgraded" to a pair of ATH-M50x which I like the sound of a little better for recording/monitoring at home, and left the M40x's at the office. I'd probably go with the ATH-M50x also considering most developers (plugins, etc...) seem to support the M50x and not the M40x just in case that matters. I like both sets, and would buy them again, but M50x has a slight advantage in my books.
