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:
- 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.
My dearest headphones are clearly the DT-880 Studios, but the 770 is very remarkable, given its low price.
