With authentic piano sound and feel, a stylish modern design, and the powerful new Sound Projection speaker system, the PX-870 is a brilliant instrument for inspiring brilliant performances.

The PX-870’s award-winning AiR Sound Source includes a new four-layer stereo grand piano which comes alive with realistic damper resonance, simulating the entire body of the instrument, not just the strings. The piano also includes key action sounds, key off simulation, adjustable hammer response, and a lid simulator with four positions. The PX-870 also includes string resonance, which exposes the sympathetic harmonic relationships between vibrating strings. Along with adding to the subtle beauty of the sound, this adds authenticity when playing works by Debussy, Ravel, and other composers who wrote with string resonance in mind.

The PX-870 features a variety of 19 instrument Tones, with the ability to layer and split them as needed. With a generous 256 notes of polyphony, you can rest assured that even the most complex performances will sound perfectly natural.

The acclaimed Tri-Sensor II Scaled Hammer Action piano keys give you the expression your performance deserves. The simulated ebony and ivory textures give you an authentic and comfortable touch, combined with an innovative hammer action that is accurately scaled across the entire key range. Adjustable touch sensitivity and hammer response allow customization to suit any playing style.

The PX-870’s innovative new Sound Projection system fills the room with rich, detailed sound. This powerful 40-watt, 4-speaker system is designed to envelop the listener and audience with sound emanating from various places on the instrument, just as it would on a traditional grand piano. The Volume Sync EQ ensures that you hear a balanced, clear sound across the entire frequency range, at any listening volume.

The PX-870's convenient features are useful at home, in a lesson studio, or anywhere else. You can connect two sets of headphones using the ¼” jacks on the front panel, making the PX-870 ideal for quiet practice. A unique Headphone Mode optimizes the PX-870's sound for headphone use. Duet Mode splits the piano into two equal pitch ranges, allowing a student and teacher to sit at the same instrument.

60 songs are included in the built-in Music Library, with room for ten additional songs of your choice. You can also record your performances using the PX-870's two-track MIDI recorder, or insert a USB drive into a discreet port to capture your playing as a two-channel audio recording. Connect via class-compliant USB to any PC, Mac, iOS, or Android device,with no drivers or installations needed.

Concert Play allows you to play along with ten recordings of well-known orchestral pieces, with the ability to either listen to the piano part or silence it so you can play it yourself. To facilitate practice, you can even slow down these recordings without affecting their pitch.

Designed to compliment any décor, the PX-870 is available in either a black, walnut or white finish. Its compact, elegant cabinet with sliding key cover adds to the beauty of any room. The easy controls are located to the left of the keys, allowing you to play without distraction.

I will buy this piano again and again


Amazing quality for the price.



Very happy pianist here


Sounds great. Keys have a nice texture that closely resembles a real piano. Highly customizable sounds. I'm very happy with my purchase. I was previously using an Alesis Recital so this was a big improvement. Many years ago I played on an upright piano.



I recommend all my friends to buy it


it has very nice quality, color and the perfect sound. I enjoy every minute playing the piano. I definitely recommend to buy it.



Tone, Touch Response, Pedal Response...Surprisingly Good!


I use this keyboard as a composing/arranging tool, for practicing/improving my keyboard/piano performance skills (I'm not a pianist, I'm a professional guitarist/bass guitarist), and as hand exercise (practicing certain piano calisthenics helps maintain my hands' muscle tone and finger independence). I needed to get rid of the old acoustic upright piano I previously used for these purposes: it had stopped holding its tuning, various internal parts had deteriorated such that repair or rebuilding didn't make sense, and I couldn't play it when my wife needed to work in the same room; an electronic keyboard with realistic piano-like action that could be played silently (and heard through headphones) was more practical for our situation. I was able to try out c. eight different makes/models several times at my local Sam Ash store; this Casio model was the best for my needs and budget range (digital piano technology has certainly advanced since the last time I really explored it). I ordered it online; the "live chat" assistant was very helpful and attentive during various moments of the ordering and delivery-scheduling process, plus he was able to help me save some money during a sale period! Thanks to Casio for an excellent product, and thanks to Sam Ash for enabling my research, selection and purchase happen so effectively.
