I bought the headphones for my Kawai CN-35. Here, however, seem a bit too much to be 250 ohms. Although I have made the setting "high-ohmic headphones" on electric piano, they are still a little too quiet, so I always play at approximately 3/4 of the maximum volume. Moreover, it sounds not always optimal compared to the internal speakers. The dull piano sounds, for example too dull. Unfortunately, there is also still a slight noise is heard when depressing sustain pedal. All in all it took me for electric piano playing unconvinced despite überragendem comfort.
Otherwise I tested the headphones even at 320 kbps and has to associate myself with the other positive reviews. The sound is really very detailed and suitable for analytic listening, the bass is neither too much nor too little. However, I have noted a slight scratching at something louder volume both on the piano, as well as music. Therefore, and due to the lack Tauglichtkeit for Piano 4 stars.
