Any different between DT880 Premium & DT 880 Pro in term of SQ & comfort on ears?
Does 32-OHM version can be played directly from iPod/Sansa Fuze without amp?
Their soundstage is mostly the same, there are some small differences in terms of sound amongst them though. I'd like to refer you to Zombie_X's thread about the Beyers, he has put some time and effort into describing them all.
The Premium and Pro versions use the same drivers but the Pro version clamps a little bit more and as such also sounds a little bit more forward. The difference is really subtle though.
The 32-Ohm version can be played direcly from a Sansa Fuze but so can the 250 Ohm version. With this said, even the 32 Ohm Beyers are known to improve significantly with amping.
