Main trade-off
Casio PX-S6000
The Bluetooth adapter occupies the same USB-A socket as a recording drive. Its supplied SP-3 is a switch pedal.
Head-to-head
Casio PX-S6000 vs Kawai ES920: Kawai keeps Bluetooth during flash recording, Casio’s devices share a port
The short answer
Choose PX-S6000 for a shallow battery-capable piano with a microphone input. Choose ES920 for chord-following backing styles, an included continuous F-10H pedal and a built-in Bluetooth connection that leaves USB available for flash recording. Casio’s Bluetooth adapter and flash drive compete for the same port. Both computer USB connections are MIDI rather than live piano audio. Kawai’s 375 mm body is 133 mm deeper before the music rest, and it needs AC power.
Before you choose
The reasoning and the trade-offs
Check what happens when the recording drive is plugged in
A player may want to stream a backing track from a phone and save their performance without involving the family computer. ES920 has built-in Bluetooth and documents Bluetooth-audio recording while leaving its USB memory connection available. PX-S6000 uses the supplied WU-BT10 in the same USB-A socket needed by its audio recording drive. That simple two-device plan therefore cannot use both accessories at once. Choose Kawai for the documented wireless play-along recording route, subject to the recording settings and source permissions. Choose Casio when singing into its mic input or keeping a shallower setup matters more.
What this is based on
Kawai explicitly lists Bluetooth-audio recording and built-in Bluetooth. Casio’s documented adapter and flash recorder use one USB-A port. No unsupported hub workaround, protected-content capture or app compatibility is promised.
Main trade-off
Kawai ES920
The bare body is deeper and there is no mic input in the complete connector list. Bluetooth MIDI also disables wired MIDI while connected.

- Choose it for
- You need the 242 mm deep body and want to sing through a dynamic microphone.
- Optional batteries help relocate practice, and you can add the documented half-pedal setup if lessons require it.
- Main trade-off
- The Bluetooth adapter occupies the same USB-A socket as a recording drive. Its supplied SP-3 is a switch pedal.
Kawai ES920
- Choose it for
- You record supported Bluetooth backing audio with your playing and need the flash-drive port available.
- You use chord-following accompaniment and want a continuous damper pedal included, with room for the deeper AC-powered setup.
- Main trade-off
- The bare body is deeper and there is no mic input in the complete connector list. Bluetooth MIDI also disables wired MIDI while connected.

Winner by situation
Start with what you need it to do
A phone backing track and playing must be recorded to flash
Casio’s adapter and drive share a port. Kawai documents built-in Bluetooth-audio recording, with normal source and recording limits.
- Casio PX-S6000
- Caution
- Kawai ES920
- Better fit
A shallow shared room and direct mic input matter most
Casio combines both. Kawai is deeper and needs an appropriate line-level mic route.
- Casio PX-S6000
- Better fit
- Kawai ES920
- Depends
Lessons require continuous damper control from the base box
Kawai includes F-10H. Casio includes an SP-3 switch and needs an optional setup.

How we reached this conclusion
Kawai explicitly lists Bluetooth-audio recording and built-in Bluetooth. Casio’s documented adapter and flash recorder use one USB-A port. No unsupported hub workaround, protected-content capture or app compatibility is promised.
The room-saving model leaves a pedal decision for the learner
PX-S6000’s bare body is 133 mm shallower, a useful saving when lessons share space with a desk or dining area. If the teacher expects gradual damper control, however, its SP-3 switch needs to be replaced by a documented optional arrangement. ES920 supplies the continuous F-10H. The shallow piano can still be the right choice, but its ready-to-practice price includes that extra if the technique is required. Compare the stand and pedal positions too. The keyboard’s depth alone does not describe where the player’s feet or chair will go.
How we reached this conclusion
375 minus 242 = 133 mm. Included pedal capabilities and optional Casio support are explicit. No accessory price or universal lesson requirement is assumed.
A solo backing band and a family singer can pull the choice apart
ES920’s chord-following Rhythm Section can accompany a person playing alone, without a finished backing track. PX-S6000 instead gives a singer a direct mic input and provides drum-pattern and arpeggiator tools. Neither feature automatically replaces the other. If adults sing while a child plays, Casio avoids a separate mic-to-line setup for that simple arrangement. If the main player wants bass and chords that follow spontaneous changes, Kawai addresses the stronger need. Both computer USB connections are MIDI, so involving computer audio later requires a separate plan whichever you choose.
How we reached this conclusion
Complete accompaniment and input lists plus computer MIDI documentation. Household roles illustrate a bounded use case rather than a promised motivation or learning benefit.

Meaningful differences
What changes the fit
| What changes | Casio PX-S6000 | Kawai ES920 | Why it matters |
|---|---|---|---|
| Phone audio and flash recording | WU-BT10 and recording drive share USB-A | Built-in Bluetooth and separate flash port, Bluetooth-audio recording documented | Casio’s straightforward wireless play-along recording plan hits a physical port conflict. |
| Singing input | Dynamic microphone input | Stereo Line In, no mic input | Kawai needs a suitable line-level source for a singer’s microphone. |
| Body depth without rest | 242 mm | 375 mm | Casio saves 133 mm before supports and cables. |
| Included pedal | SP-3 switch | F-10H continuous damper | Half-pedal practice adds an accessory to the Casio base setup. |
| Backing arrangement | Drum-pattern metronome and arpeggiator | Chord-following Rhythm Section | The two rhythm functions are not interchangeable. |
| Computer sound connection | USB MIDI only | USB MIDI only | Neither flash audio recorder proves live USB sound capture. |
What you give up
Every choice has a cost
If you choose Casio PX-S6000
- Live computer capture of its piano sound requires a suitable analog audio-input route. USB MIDI alone does not provide it.
If you choose Kawai ES920
- The same live computer-audio limitation applies. Its direct MP3/WAV flash recorder is a different destination.
Recommendation switch
The decision flips if...
Singing and a shallow battery-capable arrangement dominate
Choose Casio PX-S6000. Casio supplies the mic input and placement flexibility.
Phone-audio recording, accompaniment and the included continuous pedal matter more
Choose Kawai ES920. Kawai covers those documented routes while requiring more depth and AC power.
USB-only live computer recording is the requirement
Choose neither. Look for a verified USB-audio interface rather than treating flash recording as the same thing.
What matters in practice
Before you choose
You want to record music from a phone with your playing, but also need the piano to fit a shared room and support the kind of practice your family actually does.
What this comparison cannot tell you
- No arbitrary USB hub solution is assumed.
- Bluetooth MIDI is separate from Bluetooth audio and can have different routing restrictions.
- No guaranteed runtime, learning or sound-quality advantage is claimed.
