I have one. Replaced the ear pads with tape modded DT770 velour, and dampened the drivers with felt discs.
These GMP250 has beautiful, life like mids, deep bass and slightly rolled off highs. I use them especially for acoustic music like bluegrass because they handle acoustic instruments better than any of my other headphones, and the bass slams as it's supposed to do.
At $110 it's a steal. But they need a powerful (tube) amp. And the stock pads are not the most comfortable.
Maybe you can find reviews if you look for he MB Quart QP250, which is the same headphone. German Maestro took over MB Quart.
