Slim & Stylish Portable Design

Sound no one would expect from such a compact keyboard

The use of 13 cm x 6 cm oval speakers with strengthened magnets delivers surprisingly great sound for such a compact instrument. An additional function that optimizes the equalizer in tandem with the volume provides balanced sound from the bass to the highs, even at low volumes.

Dance Music Mode and Voices expand ways to enjoy playing
