The keyboard also features Duet Mode, which allows you to set the keys to the left and right of center on the keyboard to a similar tonal range. The Duet Mode comes in handy when two players, such as the student and teacher want to practice together.

This makes it possible to have a keyboard with a responsive touch in a unique, slim body. Additionally, the Casio CDP-S150 supports battery operation, which allows players to freely enjoy performing anywhere.

  • Casio CDP-S150 delivers a natural piano sound and feel in a slim and compact design.
  • Easy controls feature a one-button recorder that easily captures and plays back your performances.


  • Unfortunately, the piano is a bit heavy, which makes it difficult to stick it into your closet and retrieve it whenever you want.
  • It’s difficult to access the headphone jack since it is at the back of the unit.

Is the Casio CDP S150 Good?
