I've been using AKG K240 Studios for years now for mixing and tracking but also back home just listening to music or while watching tv/movies. However, I've been trying out the Beyerdynamic DT250's in the studio for a while now and found that they translate better... They give a more true presentation of the mix BUT are not that nice to listen to for long periods. They go on your ears, not around them (the same as the Sony 7506s). The AKGs are somewhat more hyped, but being that the muffs
blush
go around the ears, I can keep them on for hours. If you have glasses on, you'll appreciate that.
Beyerdynamic DT770 are also nice while listening to music, but the lows are massive on those, don't like to work on them. What else.. If you don't want to disturb or be disturbed by others, use closed phones, but note that they don't sound the same as an equivalent open-backed version and are usually more expensive.
So from my experience, for what you're thinking, I say try out the K240 Studios. Try them in the shop if you can, bring some music you know and listen 'em through.
