The One Smart Piano with Lighted-Up Teaching Keys, Top1, Black

[Upgraded Surface] The ONE TOP1X has a higher sound window and larger speaker size than PLAY, which brings richer sound and better stereo effect. Not only a good choice for beginners, but also for experienced players. [Advanced Technology] It's also upgraded to a 2.0 smart piano keyboard with graded hammer action and double-contact design, which captures the dynamics of your performance very quickly. [Powerful Education Features] Guided by built-in 88 colourful LED lights, and 4000+ sheet music, 100 instructional videos and fun games in our free APP, this digital piano enables you to start playing in minutes. It's more than a piano keyboard, but also a piano teacher. [Authentic Playing Experience] The electric piano has 88 full-size Weighted Standard Keys that are the same key size as that of an acoustic piano. While its graded hammer mechanics give you the most realistic feel, the touch response function delivers a more compelling and dynamic sound. [Sounds Quality Matters] With sampling techniques of 16-bit stereo sampling tones and 44.1KHz audio sampling rate, 128 max polyphony and triple pedal, and 4 Hi-Fi speakers including two 20W-tweeters and two 25W-woofers, this upright piano perfectly reproduces the sense of surround sound of a grand piano.
