Dear ADIer

I have a simple qustion about the sound level compared with the original source from PC or Moble phone.

When connecting the music from the laptop to the input of the EVA-ADAU1452 and listening to the output with the earphone, I feel that the output is lowered and the bass is attenuated compared to the original sound of the laptop. I do not have a measuring instrument now, so I need to find out the cause of this problem by listening to it. What causes these symptoms? Is it a problem of impedance match between PC output and earphone in EVAL-ADAU1452?
