Mu.S.E. is your musical companion for the modern era.
An embedded light sensor reads in ambient light levels
Combining this with an internal time clock, Mu.S.E. is able to automatically select the perfect playlist to stimulate your environment.
By simply swiping your hand in front of the device, Mu.S.E. automatically begins playing
Mu.S.E. sets the tone for any occasion
