From having had beyerdynamic headphones for more than 10 years including DT-880 250 Ohm, DT-990 250 Ohm, DT-770 32 Ohm, T70, T70p, T1v1, T5pv1, T51p, T50p, DT-1350 and now DT-1770 Pro I find it completely opposite. To me the DT-1990 and DT-1770 is like beyerdynamic has finally found their statement of their real house-sound. To me the soul of 1770 and 1990 is exactly what beyerdynamic has always been for me. Clean, bright, fast, open (but not Grado-like openness). The new PRO headphones is the perfect balance between all the former models. Strikingly musical but without a tiring WOW-factor that gets irritating in the long run.
