The Sony didn't improve it, it's just the output impedance of the Sony headphone port being high enough (more than 1/th the impedance of the headphone) that's is altering the FR and adding bass boost... That's not the way the HD560S sounds

Can I ask why this doesn't happen with lower impedance gear (such as oneodio, and marshall major 3) Both are 32 ohms and they sound just like when I plug them in a phone (but a little louder)....

Also thank you for answering so nicely 😊
