the natural sound for headphone listening
"We want to enjoy listening the music
with the mix balance of natural speaker sound
even if it is a headphone and earphone."

But in the studio, they are making the music using speaker.
This is the sound for speaker listening.
It is that you put the front speakers on your ears from Left and Right side.
Therefore, music mix balance that artists and engineers intended does not have to reach the ears of listeners who love headphone intact.
We should more enjoy the music by the correct music source optimized headphone and earphone listening. Then you would feel the music more deeply.
