The catch
Casio PX-S6000
The Bluetooth adapter takes the same USB-A socket that a recording drive needs. The SP-3 in the box is a switch pedal.
Side by side
Casio PX-S6000 vs Kawai ES920 on singing, backing tracks and space: Casio’s devices share a port, while Kawai keeps Bluetooth during flash recording
Quick verdict
PX-S6000 is the choice for a shallow battery-capable piano with a microphone input. ES920 is the choice for chord-following backing styles, an included continuous F-10H pedal and a built-in Bluetooth connection that leaves USB free for flash recording. Casio’s Bluetooth adapter and flash drive compete for the same port. On both, the computer USB connection is MIDI and not live piano audio. Before the music rest, Kawai’s 375 mm body is 133 mm deeper, and it needs AC power.
Before you buy
Why, and what it costs you
See what happens once the recording drive is plugged in
A player may want to stream a backing track from a phone and save their performance with the family computer left out of it. The ES920 has built-in Bluetooth and documents Bluetooth-audio recording, and its USB memory connection stays available. The PX-S6000 puts the supplied WU-BT10 in the same USB-A socket that its audio recording drive needs, so that simple two-device plan can’t use both accessories together. For the documented wireless play-along recording route, choose Kawai, subject to the recording settings and source permissions. If singing into the mic input or a shallower setup counts for more, choose Casio.
Where this comes from
Kawai explicitly lists Bluetooth-audio recording and built-in Bluetooth. Casio’s documented adapter and flash recorder share a single USB-A port. No hub workaround that isn’t supported, no protected-content capture and no app compatibility is promised.
The catch
Kawai ES920
Its bare body is deeper, and the complete connector list shows no mic input. While Bluetooth MIDI is connected, wired MIDI is disabled as well.
Casio PX-S6000
- Why pick it
- A 242 mm deep body is what you need, and you want to sing through a dynamic microphone.
- Moving practice around is easier with optional batteries, and you can add the documented half-pedal setup if lessons require it.
- The catch
- The Bluetooth adapter takes the same USB-A socket that a recording drive needs. The SP-3 in the box is a switch pedal.
Kawai ES920
- Why pick it
- You record supported Bluetooth backing audio together with your playing and need the flash-drive port free.
- Chord-following accompaniment is part of your playing, and you want a continuous damper pedal included, with room for the deeper AC-powered setup.
- The catch
- Its bare body is deeper, and the complete connector list shows no mic input. While Bluetooth MIDI is connected, wired MIDI is disabled as well.

What this page compares
PX-S6000 or ES920 for singing, play-along recording and a shared room? Find out which connections clash and when a smaller body means more accessories.
Both are premium portable weighted pianos with two headphones, two-part recording and flash audio. They differ in microphone, accompaniment, Bluetooth and supplied pedal, and they compete for the same home music budget.
Which one fits
Pick the situations that sound like you
A phone backing track and your playing both have to be recorded to flash
On Casio, the adapter and the drive use the same port. Kawai documents built-in Bluetooth-audio recording, subject to the usual source and recording limits.

A shared room that is shallow, and a direct mic input, matter most
Casio offers both. Kawai is deeper and needs a suitable line-level mic route.

The model that saves room leaves the learner with a pedal decision
The PX-S6000’s bare body is 133 mm shallower, a handy saving when lessons share space with a desk or dining area. If the teacher expects gradual damper control, though, its SP-3 switch has to be replaced with a documented optional arrangement, whereas the ES920 comes with the continuous F-10H. The shallow piano can still be the right choice, but if the technique is required, its ready-to-practice price includes that extra. Compare stand and pedal positions as well, since the keyboard’s depth alone doesn’t say where the player’s feet or chair will go.
How we worked this out
375 minus 242 = 133 mm. What the included pedals can do and what Casio support is optional are both explicit. No accessory price or universal lesson requirement is assumed.
A solo backing band and a family singer can split the choice
The ES920’s chord-following Rhythm Section can accompany a person playing alone, and no finished backing track is needed. The PX-S6000 instead gives a singer a direct mic input and adds drum-pattern and arpeggiator tools. Neither feature automatically replaces the other. Casio spares you a separate mic-to-line setup when adults sing while a child plays. Kawai answers the stronger need if the main player wants bass and chords that follow spontaneous changes. MIDI is what both computer USB connections carry, so bringing in computer audio later means a separate plan either way.
How we worked this out
Based on the complete accompaniment and input lists and the computer MIDI documentation. The household roles illustrate a bounded use case. They don’t promise motivation or a learning benefit.

Where they really differ
| Spec | Casio PX-S6000 | Kawai ES920 | In practice |
|---|---|---|---|
| Phone audio and flash recording | WU-BT10 and recording drive share USB-A | Built-in Bluetooth and separate flash port, Bluetooth-audio recording documented | A simple wireless play-along recording plan on Casio runs into a physical port conflict. |

| Body depth without rest | 242 mm | 375 mm | Before supports and cables, Casio saves 133 mm. |
| Included pedal | SP-3 switch | F-10H continuous damper | Half-pedal practice means adding an accessory to the Casio base setup. |
| Backing arrangement | Drum-pattern metronome and arpeggiator | Chord-following Rhythm Section | The two rhythm functions don’t do the same job. |
| Computer sound connection | USB MIDI only | USB MIDI only | A flash audio recorder on either one doesn’t mean live USB sound capture. |
Trade-offs
What each pick costs you
With Casio PX-S6000
- Capturing its piano sound live on a computer takes a suitable analog audio-input route, which USB MIDI by itself doesn’t supply.
With Kawai ES920
- It has the same limit on live computer audio. Its direct MP3/WAV flash recorder sends the recording somewhere else.
Change of plan
When the answer changes
Singing and a shallow, battery-capable setup come first
Go with Casio PX-S6000. The mic input and flexible placement come from Casio.
Phone-audio recording, accompaniment and the continuous pedal in the box count for more
Go with Kawai ES920. Kawai handles those documented routes, but it takes more depth and needs AC power.
Live recording to a computer over USB only is a must
Neither model fits. Look for a verified USB-audio interface, and don’t treat flash recording as the same thing.
Decision guide
Before you buy
You want to record music from a phone along with your playing, and the piano also has to fit a shared room and suit the kind of practice your family really does.
What this page can’t tell you
- We do not assume any arbitrary USB hub solution.
- Bluetooth MIDI is not the same as Bluetooth audio, and its routing restrictions can differ.
- We claim no guaranteed advantage in runtime, learning or sound quality.
