I mixed on set for years on MDR 7506s. I find them too bright for normal listening but the extra high end is great for hearing set noise. One day I got tired of dealing with the wind noise issue. Wind gets between the ear cup and my ear and makes noise, and in the moment I can't tell whether the noise is coming from the mic or from the lack of isolation from the on-the-ear design. Granted I have big ears, so this may not be a problem for most users.
I have since switched to Shure SRH840s. They are an around the ear design so I don't have the wind issue anymore, and I enjoy the extra isolation. And they're not as bright as the Sonys so I get less ear fatigue on long sessions. The bass is not as hyped as the Sonys, but it's not as tight either. And midrange is a littler sweeter on the Sonys. But overall they have a flatter representation, which I enjoy. Not as scooped or smiley as the Audio Technicas and way better midrange. They're also lacking the boxy bandpass sonic signature I hear in Beyers. Several friends have made the switch after using mine.
