I'm doing most of the work with a HD 600 as well. A confortable headphone with a high quality sound.
Keep in mind: The HD-600 is an "open" model (I don't know whether this is the correct expression or not).
If you are looking for a headphone for live recordings it wood be better to get a "close" one.
Kind regards
