Casio PX850 Privia 88-Key Digital Piano Review

Casio PX850 Privia Digital Piano (Black)
The Casio PX850 Privia instantly became a top seller among digital pianos, and for good reason as well. The PX850 is one of Casio’s newer and most popular models, improving upon its hugely popular predecessor, the PX-150, in almost every way imaginable. For this reason, the Casio PX850 Privia  is now well known as one of the best digital pianos on the market for under $1,100.

Here is our review for the Casio PX850 Privia 88-Key digital piano. 


Right away, you’ll notice that the Casio PX850 Privia looks very professional. The design of the PX850 is even nicer than some of its main competitors, like the Yamaha P150. The Casio Px850 also comes with a designated stand and three high quality pedals, while Yamaha requires you to buy these things separately.

The PX850 is available in three different color schemes, black, white, and brown. Many digital pianos have a hard time pulling off the white or brown styles, but Casio has managed to do a good job with it. All the colors look natural and smooth, and performers using the PX850 are bound to receive compliments for the wonderful look of their piano.Casio PX850 Privia Digital Piano (White)

One unique feature worth mentioning is the ability to open up the top of the piano, in a similar way to an acoustic grand piano. This makes the piano look even more elegant, while allowing the sound to more easily project out into the room.

As far as weight goes, the PX850 is quite a bit heavier  than a lot of other digital pianos in its price range. It weighs 81.5 pounds without the stand, which makes it a more difficult to carry around. However, it can still be lifted and carried with only one person, meaning it will still serve you well if you are using it for performance purposes.

Feel Of The Piano

The Casio PX850 Privia feels like one of the closest digital pianos in its price range to a real acoustic piano. All 88 keys are made to replicate the feel of an acoustic, and they do a great job. The white key shave an ivory feel to them, and the black key tops are finished with ebony. All of the keys use tri-sensor scaled hammer action to match the feel of an acoustic when the keys are pushed down. The lower keys are heavier to push down, while the higher keys of the PX850 are lighter.

One feature of the keys worth noting is that the  sensitivity level can actually be adjusted. Some digital pianos have key sensitivity issues, causing them to either push down way too easily, or not easily enough. This causes the keys to feel ‘fake’, and playing these types of digital pianos make it hard to transition over to an acoustic should you need to do that. This isn’t an issue with the PX850, which has three sensitivity options – soft, normal, and hard. This allows you to make the PX850 feel exactly like you want it to, and match it as closely as possible to other acoustic pianos.

Sound Of The Casio PX850

While the design of the PX850 is top-notch, the sound of the piano is far more important. Luckily, the sound of the PX850 is superb, drastically improved over its predecessor. Casio uses new ‘AiR’ (acoustic and intelligent resonator) technology to simulate the sound of one of the world’s best grand pianos. Casio also allocated 3x the amount of memory to processing sound, and it definitely shows when you compare the PX850 to its predecessor.  Take a look at the video below to hear a beautiful sample of the PX850.

While the built-in speakers are a big improvement over earlier models, the PX850 still sounds best when it’s plugged into an external amplifier. Performers will already be using one anyway, so it shouldn’t be too much of an issue. The speakers still sound nice for in-home use as well.

Additional Features Of The Casio PX850

The Casio Px850 has many additional features that separate it out from its competitors. These include, but are not limited to:

Key Transposing
