Different pros: Evaluated only the sound quality over the wire from a relatively decent source (DX120) and how they sit on their heads. I only studied the headphones in the store, and did not buy them. The advantages of the sound - I can not single out. But I'm very picky, music lovers on the sly. The head is squeezed with such an effort that it sits securely and does not fly off, but at the same time it is not particularly strained by compression. Has cons: As soon as I put it on, I immediately felt that the bow was pressing from above. It's not flat, it's not soft. It is resilient, and with its pressure draws attention to itself. The price is high. But the main thing is the sound. In the LF region, maybe a little closer to the middle, some kind of frequency response hump is heard. This resonant frequency puts pressure on the ear, which is why it is impossible to say that the bottom is "transparent", etc. For this price (27000) I naively expected more sound development. Although, Sony has never been considered a music company. Other frequencies, detailing, the scene - I didnβt even evaluate it, sorry. I really didn't like that shortcoming in bass. I can't listen to these ears.
