Casio Privia PX 850 Piano Review

Casio Privia PX-850 Piano

The Casio Privia PX-850 Piano is the new flagship product in the Privia series. It provides you with top class piano sounds, and the feel of real piano from hammer response to damper resonance and lid simulation.

There’s a newer version of this model: Casio PX-860.


With the Privia PX-850 digital piano, Casio has attempted to give the user a more realistic sound and feel of an acoustic grand, by providing hammer response to keys to damper resonance and even lid simulation.

It’s easy to assemble (you may require another person’s help though) and has excellent sound quality, looks & features.

Who Is It For?
Perfect for home, church or the studio, the combination of a new keyboard action and a powerful new sound engine makes it a force to reckon with.

Now you can get a much better control over the nuances and the expressions, while playing the piano.

Those who have played a lot on proper pianos will find the pedals on the Casio PX850 to be smaller in size, compared to the size of standard piano pedals. That can be a bit inconvenient and will need time getting adjusted to. Is that a reason to complain? Remember, this one is priced around 1000 dollars.

Competition Check
There was a time when the name “Casio” used to be associated with toy pianos, but no longer. In fact, one of the other option that you could consider is the Casio AP420 or maybe the more expensive Casio AP620. These Celviano series are designed like classic pianos, have better cabinet designs & color, and also come with built-in music lessons.

The PX-850 however is more of a performance piano (alternative for acoustic piano) and doesn’t have built-in lessons. However, you can always connect it to a computer to work with music educational software, or connect it to iPad and use apps such as Home Concert Xtreme for lessons.

Another option to consider is the Yamaha YDP series. It’s more of a personal preference, however within the same price point, you can expect a few extras from Casio. For example, if the YDP gives you 128 note polyphony, you can expect 256 from Casio.

You can go in for the more expensive Yamaha YDP-181 but it has been around for some time and could be due for an upgrade. The new Casio PX-850, at this price point, however looks far more tempting (about 500 bucks cheaper).

If you want a much better product, then should probably look at the Yamaha Clavinova, but then they are quite expensive.

Same goes for the pianos in the Roland HP500 series and the Kawai CN series, which are better products, but priced more. In case, you’re looking for something slightly cheaper, the Casio PX350 is a good option to consider.

All Casio products have a standard 1 year warranty, but their pianos have an additional 2-year warranty which you need to activate through their web site,

once you buy the Casio piano. So overall, the total warranty is 3 years on parts and labor, which is not at all bad.

Overall Ratings

The PX-850 is a great alternative to an acoustic piano, and comes with a powerful on-board speaker system, and a cabinet that opens providing a rich concert sound. Now you can easily fill the room with big piano sound.

Some players also wish that the volume knob and the buttons for switching instrument tones were located somewhat above, and not just above the keys. Because some of them tend to touch them while playing. But then, they are not very close to the keys, and you have to be really sloppy to touch it. With some time, you’ll become aware of it & get adjusted to it.
