Casio PX-870 Review for 2023UPDATED REVIEW – May 25, 2024 | Casio PX-870 Digital Piano | LOWER PRICE HERE | The Casio PX-870 at $1199 price (piano bench optional) has now risen to the top in popularity of all newer furniture cabinet digital pianos under $1200 as compared to other brands including Yamaha, Kawai, and Roland based on all the numbers and orders we see for a new furniture cabinet digital piano in this price range.
In our opinion this model definitely deserves “Biggest Bang for the Buck” award in its price range for a furniture cabinet model for a number of compelling reasons. With 40 watts of stereo audio power going through 4 speakers (which is unusual in this lower price range) and top sound projection ports along with the largest amount of piano polyphony power available in the price range (256 note polyphony), the PX-870 is the most popular model under $1200 based on all the indicators we have seen as well as our personal experience playing it.  
UPDATE: May 25, 2024 – For a very limited time the Casio company is offering a $200 instant rebate on the very popular PX-870 which makes the final price $999. Given that Casio rarely does this kind of thing, should you want to purchase this Casio digital piano then you need to do it ASAP while you can still get this instant rebate. Getting $200 off is a lot of money saved on a $1200 digital piano like this one. That’s about 20% off.
Keep reading our review and if you believe this model is what you’re looking for then let us know and we can not only reserve one for you, but save you even more money along with no sales tax and complete factory warranty.
Casio PX-870 digital pianoThe Casio PX-870 is available in matte black, matte brown, and matte white and is sold at $1199 internet discount price. In our opinion this is relatively low price for what you get in this digital piano. It has some big improvements over previous models such as including a 3/4 height back privacy panel on the cabinet so that you cannot see through the piano from the front, a sliding key cover, and its contemporary compact size furniture cabinet design.


Casio PX-870 with key cover closedThe PX-870 model has a noticeably improved piano sound sample which has been upgraded in realism and piano dynamic range & expression along with a longer sustain pedal decay time for more realistic sustained piano tone. On top of that, the internal speaker system has also been upgraded in a way that projects the sound out of the piano in a more natural way using “sound escapement chambers” on the top of the piano which no other piano has in this price range with sound coming out of the top as well as forward towards you. So for $1199 the PX-870 is quite impressive and a winner for a furniture cabinet digital piano over the other brands and models in this price range based on all our experience with digital pianos.


Casio logoWhen it comes to the Casio company, just about everyone knows that name for every day consumer electronic products such as calculators, watches, cash registers, projectors, electronic keyboards, and many other items for the last 60+ years. Casio of Japan is a large world-wide company which has the reputation for packing a lot of cutting edge technology into reliable low priced products that give you a “big bang” for the buck. With their home & pro digital pianos they do the same thing and it just keeps getting better every time they come out with a new model.
Casio headquarters in JapanUnlike Yamaha & Kawai, Casio does not produce regular acoustic pianos and unlike Roland they don’t produce high priced electronic pro keyboards, guitars, drums, or other high end music gear. But what Casio does well in my opinion is make great innovative and competitive digital pianos for very low prices using the latest and greatest technology in a way that no other digital piano company has done so far under $1200. So when it comes to getting the most bang for your buck I can tell you right now that based on my playing experience with this model, everything I have seen & heard on the Casio PX-870 in its compact furniture cabinet is very impressive.


lower prices than Amazon or Internet



1. The piano sound is noticeably better than on the previous models because the piano sound chip was upgraded to be even more natural like a real piano with better expression and more organic piano tonal elements than before. You can really tell the difference if listening to both models. Also there is one more acoustic piano sound added along with some of the non-piano instruments that have been re-voiced and improved for greater authenticity. The stereo strings, choirs, harpsichord, electric pianos, etc, really do sound good and are a joy to play especially as compared to other digital pianos in this price range.

2. The sustain pedal decay time has dramatically improved so that when you hold down the sustain-damper pedal you will hear more sustain volume and noticeably more sustain decay time than ever before and when that happens you get a more organic & natural piano sound particularly when playing legato and using more sustain pedaling. The notes of the piano sound mix together more evenly and produce a smoother and more balanced tonal expression across the entire 88 keys that was not able to be achieved on the previous models.
3. The speaker projection system has changed on the PX-870. The former models had a hinged lid where part of the lid could be propped up so the piano sound could come out of the piano top. That was a very good idea but the down-side was that with the lid propped open, you could not rest any music, music lamp, or any other items on the piano top because they would fall off. Casio designed a new speaker projection system that allows the piano sound to come up and out of the piano top without the need of a lid.
There is a brand new speaker system in the piano that diverts part of the piano sound up and out through a long but narrow speaker grill that goes the length of the piano top and is inset and flush with the top. It’s located more towards the back top of the piano. The piano sound is also projected forward through speakers in the piano. 
In this way there is better sound disbursement and top remains closed so it has a sleeker look, no more hinged lid like the previous model that could potentially break, and you can put things on the piano top without those items sliding off because of the previous models’ partially raised and tilted lid. These are very well designed improvements that upgrades this new model in a noticeable way.
4. The synthetic ivory white keys and ebony black keys have been re-textured with a new material that brings the touch/feel of the keys even closer to that of the popular natural ivory acoustic pianos of past years…a noticeable improvement with a smoother feel.
5. The headphone listening experience has been improved over the previous models with new “headphone mode” with improved electronics that creates a more realistic stereo listening environment when using any good stereo headphones.
6. A Volume Sync system has been added to the PX-870 which allows the piano to have better low frequency response when playing the piano at lower volumes which is a good thing. This type of electronics has been available in digital pianos before but not in this price range.
7. The cabinet has been upgraded to look better with fewer seams in the case as compared with the previous model and the control panel buttons have been re-positioned to the left side of the keyboard to make the piano look simpler in design and less cluttered than before. Also the physical cabinet assembly process is more intuitive than on the previous model with cabinet parts able to be connected more easily.


Casio Music Space controller app

Casio also has a new proprietary iOS/Android app for the PX-870 called “Casio Music Space” which allows the piano to be connected to the app on your iPad for further (and better) control of functions & features. The PX-870 controller app makes using the PX-870 a breeze as compared to using previous models and trying to figure out how to access many of the piano features. Now those functions can be accessed on the PX-870 using your tablet color touch screen with a very intuitive app with many screen/page choices to control all of the major functions of the piano like never before in a Casio digital piano. Other digital piano brands have controller apps as well, but the Casio Music Space app seems to be much more advanced and also includes some educational music games, song playing features, and PDF sheet music scores of the many built-in piano songs within the PX-870. If you do not have a digital tablet (like iPad, etc) then the new PX-870 would be a good excuse to get one!


Casio triple sensor key action

As far as the the rest of the piano goes, and especially with the key action, Casio has kept their popular 3-sensor per key-weighted-graded piano style key action in the PX-870 which was also in the former model. I believe they’re doing this because so many people who owned the prior model really liked the key weight, balance, and movement of that key action so it has not changed and 3-sensors per key helps with better key repetition recognition. When it comes to shopping for a new digital piano, the key action should be considered the most important part of the decision making process for most people including piano students.


Casio PX-870 pianoPersonally I like the Casio key action better than the other furniture cabinet pianos under $1200 internet price and it feels more like an acoustic piano in a number of ways. The touch-weight and up-weight key response (when the keys are moving down and up) seem to be very responsive, they have a good fast reaction, and the weight of those keys is not heavy and not too light. Some digital pianos in this price range have key actions that are either too springy and don’t feel like piano keys, or the keys are too heavy and can cause hand, finger, and wrist fatigue. The Casio key action is enjoyable to play whether you are a beginner or more advanced in your playing skills.
Be aware that no digital piano in this price range actually feels exactly like a real acoustic piano, but this one comes pretty close, and for most people, including more advanced players, you can take your music pretty far on this piano. Also as I mentioned earlier, the new synthetic ivory and ebony key-tops have been improved from past models and are much smoother with a better tactile feel, and I noticed this right away when I played it. The synthetic ivory and ebony keys also help with absorption of moisture from your fingers so that the piano is more enjoyable to play if you’re the type of person who has sweatier fingers.

Another interesting feature Casio has created is their new reverb settings call Hall Simulation effects which gives the stereo acoustic piano sound more spacious effects such as you would hear in a large concert hall or church where there is natural echo that occurs when playing an instrument. There is a variety of different “Hall Effects” you can choose from and they really are impressive because you don’t normally find this kind of feature on a digital piano in this price range. It adds to the sonic presence of the acoustic piano sounds and can make the piano more enjoyable to play. I have heard these kinds of effects before in other higher priced digital instruments and they can add to the realism of piano playing, but these effects are not always necessary or appropriate especially with some pop or jazz. But overall it does make a huge difference


256-note polyphony

A big advantage not offered on other digital pianos in this price range is the 256-note polyphony piano sound processing technology.  More polyphony note processing power helps to keep notes from electronically dropping out when playing difficult & musically complex passages along with being able to layer two sounds together and using the damper pedal without note dropout when playing multiple notes together at the same time. Also, like many name brand digital pianos including Yamaha, Kawai, and Roland, the PX-870 offers the “half-damper” pedal sustain feature with pedal resonance effect which helps recreate the real acoustic piano pedaling  damper/sustain sound for more intermediate to advanced piano music.

For those students and recreational players who are at a more beginner skill level, they will have something to grow into instead of grow out of, and because of this your piano teacher (assuming you have one) will be happy too.

The PX-870 is upgraded in big noticeable ways over its competition such as Yamaha in this price range. Although no digital piano that I know of actually sounds exactly like a real acoustic grand piano (I play real acoustic grand pianos and know what I’m talking about), the new PX-870 gives you the definite impression that you are playing a real acoustic piano more than other brands and models do in this price range in my opinion. The dynamic tonal range changes when playing the keys softly or with greater force is noticeably wider than Yamaha and allows for a greater range of musical expression.

Casio PX-870 dynamic tonal range

This is especially important if you are taking lessons from a good teacher or you are at a higher playing skill level.The sonic quality of the Casio’s new piano sound especially going through its new speaker projection system in the top of the piano is very impressive across the entire keyboard and is something which can be enjoyed no matter what type of music you play.  If you are able to spend more money and/or are at a higher playing skill level (or want to be), then there are certainly other digital pianos to consider in a higher price range.

Casio has included in the new PX-870 another popular feature from the prior model which is a music library called “concert play” which consists of 10 orchestra classical songs (plus more you can download from an internet site) which you can play along with using the piano sounds from the piano. The 10 songs are in an audio wav format (recorded from an actual live orchestra) and it sounds just like a real recording of the instruments as you would have on a regular CD. The 10 songs are standard classical music and although they are fun to play along with and do sound good, you would need to be able to read music (or play by ear) and play along at the song skill level so that you could interact with the music properly.

Casio Chordana appYou can slow down the songs a bit which is helpful for learning, mute either right or left hand sound to play-along with and also do a few other things with the orchestra accompaniment which are helpful for learning. It’s a very cool feature and sounds good but there are only the 10 built-in songs available which are all in the classical category. The PX-870 also has 60 built-in well known classical piano songs that you can play along with using the new Casio Music Space app and also displays the sheet music to those songs. You pretty much have to know how to read music at a bit more advanced sight reading level for those songs to play them accurately, but you can also just play along by ear and have some fun doing it that way.

Another impressive feature that Casio has included in the PX-870 is “wav file” audio recording like they had in the previous model. This features allows you to record yourself as an audio recording (CD quality) and save it to a USB flashdrive in the piano. Then you can take that recording in the flashdrive and play it back on the piano and also plug the flash drive into your computer and play it back there. You can also email that song to your friends and relatives so they can hear it on their computer just as you played it. Nice feature to impress your friends and relatives and you can convert that file to MP3 on your computer for posting on social media sites. Beyond that, you can import that music into computer music programs for music education, composing, song arranging, etc for further musical interaction.

Another very useful recording and playback feature is the 2-track left & right hand MIDI recorder. This feature enables the student of player to record their left and right hand parts independently from each other and then you can play either part back and play the other part live along with it. This is just like a teacher would do it playing one hand while the student plays the other hand.

Now you can do the same thing all by yourself by playing back your recorded part while playing back the other hand “live” at the same time along with being able to slow down playback tempo while practicing your parts…very cool and great for students.


PX870 - Audio Projection ports

As I mentioned earlier, the new Casio PX-870 “piano top” audio projection system is a very innovative feature not found on any digital piano I know of under $1100 (see pic on left). The piano sounds can rise out of the top of the piano at all times through a special top speaker system with sound coming through a speaker grill at the top back portion of the cabinet going the length of the piano top (see left pic)  rather than be on a hinged lid like the previous model. This allows for a continual projection of the piano coming out of the piano like a grand piano would do through its open lid.

The downside of the previous model hinged lid is that you needed to prop it open on an angle and then could not rest anything on the top of the piano like a music lamp, sheet music, or other objects because they would fall off. Also the extra sound could only be heard by the “player” and not coming up into the room. In my opinion this new sound projection speaker system gives the player and listener a more realistic piano playing and listening experience.

Casio PX-870 cabinetThe internal 40 watt 4-speaker sound system with projection ports simulates the “open lid” of a baby grand with the top opened up.The overall sound on this model can be quite loud and resonate so there is no need to attach external speakers to this piano in my opinion and the volume and quality of sound from the piano will easily fill up a big room.

Other features of this new piano include split & layering of instrument tones, an adjustable speed digital metronome for rhythm & timing training, key touch sensitivity adjustments to personalize your playing, duet keyboard function allowing for two people to play at the same time, and other useful features including two stereo headphone jacks for two pairs of headphones so you and another person can have private practice. One thing I was a bit disappointed about on the PX-870 is that it does not have audio line output jacks. This type of connectivity can be important if you want to connect your piano to an external sound system through dual mono outputs to send the stereo signal out that way. On the PX-870 you instead can connect from the piano to an external sound system via one of the stereo headphone output jacks so it can work that way.

right front side of pianoOn most digital pianos if you connect in that fashion then once you are plugged into the headphone jack then the internal speakers of the piano shut off which can be quite inconvenient.However, Casio has wisely included a special speaker output mode on the PX-870 that you can activate which will keep the internal speakers on even if a headphone jack is being used…and that’s pretty cool.

The control panel and buttons are set off to the left side of the keyboard to minimize the buttons and give the piano a “cleaner, less cluttered appearance which is nice and you can make sound and function selections on the control panel, using the function button while pressing a designated function from the keys on the keyboard, or using the proprietary Casio Music Space app from the color touch screen of your tablet device and being able to control all of the functions intuitively that way which I mention again below.

It is important to note that the PX-870 piano does not have built-in drum rhythms, automatic chords, music styles, hundreds of instrument sounds, multi-track General MIDI song playback, LCD display screen, or other so-called “bells & whistles” that can possibly take away from a true piano playing experience. The PX-870 is focused primarily on the piano playing and is a very impressive piano for its price, especially as compared to any other digital piano brand or model near this price range, whether you are a beginner student or more advanced player. If you want some additional interactive features for the PX-870 you can easily connect to an iPad (iOS device) and experience some very cool piano educational & fun music technology that way which both adults and children will enjoy.

I use that feature (iPad apps) all the time in my teaching studio and my students love it and it helps motivates them to want to “practice” more often and that’s normally a challenge for many students to do:).


Casio Music Space app reverb controlSpeaking of educational apps, as I mentioned earlier, Casio has their own extensive iOS and Android app for the PX-870 digital piano called Casio Music Space.For the first time in the Casio company history, allows users of their newest digital pianos, including the PX-870 to control many of the most popular features in their new digital piano directly from a mobile or tablet device connected to the USB output of their digital piano. Until now on Casio digital pianos, controlling the sounds, built-in songs, and digital features such as layering, recording, etc had to be done from the piano control panel exclusively.


Casio Music Space - layering control

Although this is a good way to do it overall for many of their functions, there are some features that are not as as intuitive to use and this is true for the other digital piano brands as well.So Casio has PX-870 features that can be directly and remotely controlled from your tablet or mobile device using that app’s very cool user interface from your device color touch screen along with other features in the app such as educational games, sheet music, and a number of other things that exist in Casio Music Space app. Having this new controller app along with what you can do on the piano without the app makes this new PX-870 fairly unbeatable in my opinion, especially given its lower price under $1200.

pic of left side control panelThe PX-870 digital piano has a big piano sound for its price range which can replace a regular upright piano along with enough digital features to make the learning and piano playing experience fun and gratifying for most people seeking a quality instrument in a low price range under $1200. Speaking of low prices, in the distant past I would have also recommended that people consider buying a good used acoustic or digital piano instead of a new one because good new digital pianos used to be a lot more money than they are now. However, the newer digital pianos for 2023 like the Casio PX-870 are so improved and relatively inexpensive that it makes buying a used acoustic or digital piano almost a non-issue in my opinion.

Plus, you take a risk when you buy an older used piano (digital or acoustic) because it is purchased “as is” and you get no factory warranty. Plus with acoustic pianos they constantly go out of tune.
Casio PX-870 piano - reviewAlso, you cannot play them quietly (no volume control and always loud) nor is there a headphone jack for private play.There are also always risks in buying anything used including older used digital pianos because there are no guarantees they will work properly.
So do yourself a favor, if you are looking to keep the price near the $1200 price range for a digital piano, in my experienced opinion the Casio PX-870 is a clear winner in this price range for a furniture cabinet piano that is reliable and comes with a 3 year factory warranty for parts & labor.

It has resonant piano sound, responsive piano weighted key action, good pedaling functions, and enough extra interactive features to keep you busy for a long time. So unless you are motivated to go into a higher price range to get an upgraded digital piano beyond what the Casio PX-870 offers, then for the money the PX-870 in our opinion is the way to go for a furniture cabinet digital piano.

  1. Hi Tim. Do you know if the panel lock is persistent, i.e. will remain in effect after a power-cycle? This turns out to be an important feature for me. I have a 4-year-old son who will be distracted with the buttons. The Kawai ES-8 has persistent panel lock, but a lot of others will lose the lock after a power-cycle.

  2. I am very interested in this Casio! I have a Kawai es110 now and am wanting something in a cabinet with more volume and fullness in sound. I do have a question however. I am aware of the price difference but am wanting to compare the px870 with the Yamaha ydp163, another model I am currently interested in. The Yamaha certainly does look prettier but will it sound better? Thanks for your help.

  3. Hello Tim, thanks for such an amazing review. I am between the Casio PX870 vs Kawai KDP90?. The main two features I am looking for include a realistic key action and sound. Which one would you recommend for a beginner? Thanks a lot. JC.

  4. Hi Tim, Great review as usual. For beginner whose priorities are sound and key action would you recommend a Roland F140R or the Casio PX870? TIA

  5. actually both are nice but the new Casio PX870 has a more natural piano tone and easier to play, along with a much better sound system in the PX870. The F140R has some nice technology features such as drum rhythms, music styles, and a Roland iOS app to play around with using bluetooth connection, but I like the Casio for piano playing

  6. Hey Tim, you mentioned you use Ipad apps for learning in this review, Which ones do you use or would recommend? thank you.

  7. Would you pick the PX560 over this? I realize they are intended for different markets but it seems the 560 has more to offer with the same piano capabilities

  8. How does this compare to the Roland 501R? I like the Casio feel of the keys and I hear that Roland is similar.

    I also like how the Roland has user upgradable firmware.

    I guess I want to know if it compares well with this model?

  9. Some years ago you helped me choose a Casio PX850 which is working fine but would the PX870 be an upgrade? I'm more concerned about which would feel more like an acoustic and be more accurate given an acoustic piano is not an option. Thanks!

  10. Hello Tim,
    thanks for your very helpful review!I´m about to buy my first piano and have no experience. For me, it´s hard to opt between the Casio PX-870 and the Kawai KDP110.
    Could you tell me, which one you would choose and? Thank you!!

  11. Hi, what do you think about AP-270? In Brazil the AP is only slightly more expensive. Do you think the steinway sample is worth? The keys are better?

  12. Hi, thank you for your review on Casio PX-870. Can you confirm that the warranty is 3 years for both parts and labor? I am coming across sites that say manufacturer warranty is 1 year. Thanks.

  13. I wanted to add my comments here for Tim as I purchased this Casio PX-870 last week from him.

    I spoke to Tim at 6PM on Tuesday, April 5, 2022. Tim and I spoke for about 30 minutes and he answered all my questions. I am abbreviating my conversation with Tim as it is a long story to tell. 🙂 Tim was very accommodating and I found him so easy to talk to.

    I then ordered the piano from Tim that same night during our conversation. By the way, I already had an order placed with Amazon and I cancelled it while I was on the phone with Tim. I sent my Paypal deposit from a purchase order that was generated by AZ Piano Wholesale which was around 9:11PM already. I then received confirmation the next day, April 6 at 4:41PM from Fed-Ex and that the shipment information was already received by Fed-EX.

    At 6:45PM, Fed-Ex confirms possession of the piano at their facility. I have been following the progress of the Fed-Ex delivery as I have signed up for alerts. Once I received the Fed-Ex shipment information, I mailed out a personal check to Tim to his Glendale address. I received an alert from Fed-Ex that the piano will be delivered to my address on Saturday, April 9. Well, guess what? I received the piano on Saturday, April 9 at 10:41AM.

    Since I worked last Saturday when the piano was delivered, I wasn't able to assemble it till later that evening. I was playing with the piano by 8PM that Saturday. I am just a very happy customer with my choice I made regarding this piano. To me, it has all the bells and whistle that I need as I am only a beginner. This will be my first time to study and learn to play a piano.

    The PX-870 can also interface with the Casio Music Space and Chordana apps. It can control how the tones can be selected easily and a ton of other features. This adds a new level of control for the PX-870.

    Just for reference, I am a 67 year old guy who just wants to have fun learning to the piano.

    By the way, Tim, you can change the settings of your blog so that the newest comments are at the top of the blog.

  14. I just had a nice long conversation with Tim. I found Tim to be a really nice guy and made me feel comfortable and that I made the right decision during my research for a digital piano. I have been on YouTube and Google.

    I happen to decide on the Casio PX-870 and he reassured me that I made the right choice for choosing this model. So, I cancelled my Amazon order while I was on the phone with Tim and ordered the piano with him instead because Tim had a better price for me.

    I am a true beginner with regards to playing the piano. I decided I want to learn to play the piano while I still can. I am a retired Electronics Engineer and I went with my gut feeling as far as the specs of the PX-870 is concerned. I figured one of the specs which is the polyphony of 256 is better than the 192 of the Yamaha. There are other differences too but I will not go into it here.

    The software that supports the PX-870 is superior to the other apps that I have seen. I have been playing with the Casio app while I am waiting for the piano and it has a lot of functionality even when it is not connected to the piano. I have also downloaded the other apps for comparison and I found the Casio app better than the others.

    Thanks again, Tim.

  15. I am not a musician but an engineer. Since Tim has already reviewed the AP-470 also, it might be a matter of your preference since the Celviano is higher up on the scale of the Casio Electronic Musical Instruments than the Privia.

    Comparing the amplifier specs of the PX-870 vs the AP-470, they both have 20W + 20W, 12 cm x 2, 4 cm x 2, 2-Way, 4-Speakers. The rest of the specs are pretty much exactly the same except for the number of tones which is 22 (Ap-470) vs 19 (PX-870).

    So, Tim can definitely answer the question of whether the AP-470 sound as good as the PX-870 or the other way around if the PX-870 sound as good as the AP-470 since the price of the AP-470 is $1699 when I googled it and the PX-870 is $1099.

    I am happy with my decision in getting the PX-870 instead of the AP-470 as I was also looking at this model when I was in my selection process.
