To be honest, I decided to save a little money and buy these headphones made specifically for the Kawai electric piano, rather than the more expensive ones I tried in the store. I was not mistaken in that, the sound from the piano is excellent and rich. The only drawback, in my opinion, is that my auricle does not fit completely into the ear pads - after all, the ear has an elongated shape and oval ear pads are more suitable than round ones. But this does not affect the sound quality or comfort. The headphones do not press and you can play for several hours. But there is one drawback that is NOT directly related to the headphones. When you take off the headphones, the sound from the electric piano seems very flat, since the built-in speakers are significantly inferior in quality to the sound that comes through the headphones.
