My DT-880's are the Premium 250 Ohm, probably only subtle differences performance-wise from your Studios. They have become my favorites, too, I can totally understand how they made the top of your list.:TI am using several pairs of cans for different purposes:
My dearest headphones are clearly the DT-880 Studios, but the 770 is very remarkable, given its low price.
- BeyerDynamic 880 Studio (20+ years old, 600 Ohms, open or semi-open): for listening to music, when I find time to do so. Very HQ phones, which I prefer for classical and jazz music
- BeyerDynamic 770 (250 Ohms, closed): for listening, when I need hard stuff with heavy bass at near ear bleeding levels - which happens occassionally
- Stax SR40 (with simple SRD-4 adaptor, driven by a separate T-amp): just close-by at one of my stereo set-ups. Quite relaxing sound, very clear, but a bit light on bass
- Koss PortaPro (15 years old, open): while travelling. I haven't found anything better in such a small form factor at a price tag anywhere that affordable
- Sony MDR-ZX600 (closed): mainly for portable use while filming or travelling, but simply less resolution, than even the lowly Koss Porta Pro and not anywhere comparable to the rest of the bunch.
