I'm professional musician and I bought it for my home studio. I own also Sennheiser HD 449. From my perspective It might be difficult to mix and master on these AKG if you are not used to them because they are heavy on bass and middles, sound is not balanced. HD449 are more suitable for that purpose because they are more balanced. I still use AKG in the end to check if song makes even more impression in good headphones. Anyway, If buy them for listening to the music - they are the best. The sound is brilliant - good mids, punch in the bass, very clean highs.
