For closed ones DT770 should be one of the better ones for price so are you after bigger soundstage?
Open headphones like DT990 Beyers or AKGs have that.
Though of course at the expense of external sound isolation if you don't have quiet environment.
If it's microphone you're there's ModMic for turning any normal good headphones to headset.
Also Beyerdynamic's DT770-990 design is DIY modding friendly:

Headsets themselves are rarely comparable, at least without price taking jump.
Beyerdynamic MMX-300 (QPAD QH-1339 is custom version) is DT770 + mic and special product extra in price.
Cheaper ones tend to be based on lower model headphones.
And headphones with truck load of Chinese garbage drivers aren't any better.
Just getting that single driver to work well with headphone casing is always challenge, so multiple drivers don't make it easier.
Good stereo headphones and binaural sound are there for getting "3D" sound with headphones:
