The catch
Casio PX-870
The cabinet alone is 34.3 kg, before packaging or delivery access come into it.
Side by side
Casio PX-870 vs Casio AP-S200: PX870 continuously detects pedaling, and AP-S200 includes wireless connections
Quick verdict
For phone music and wireless MIDI with no adapter to buy separately, the AP-S200 is the choice. When continuously detected damper response is the stronger priority, go with the PX-870.
Before you buy
Why, and what it costs you
Swapping pianos can leave the cabinet footprint unchanged
Both are listed at 1393 mm wide and 299 mm deep. If that footprint already fits your room, switching between the models needs no more listed floor depth. The keyboard mechanisms differ, and they still deserve a trial. Equal dimensions do not mean equal key feel.
Where this comes from
Listed width: PX-870 1393 mm, AP-S200 1393 mm. Depth before music rest: PX-870 299 mm, AP-S200 299 mm. Keyboard mechanism: PX-870 Tri-sensor Scaled Hammer II, AP-S200 Smart Scaled Hammer. This is a conditional workflow inference drawn from these documented inputs. There is no matched performance measurement.
The catch
Casio AP-S200
The damper has two levels plus off, which is not the continuous detection the PX-870 offers.

What this page compares
Casio PX-870 vs Casio AP-S200, compared on keyboard mechanism, damper response and included Bluetooth audio reception, plus the practice routines that decide the better choice.
Both of these Casio consoles list the same width and depth and record audio to USB memory. Included wireless connectivity is what the AP-S200 adds, whereas the PX-870 documents continuous damper detection.
Which one fits
Pick the situations that sound like you
You are picking a piano for a console space you have already measured
Both are listed at 1393 mm wide and 299 mm deep. If that footprint already fits your room, switching between the models needs no more listed floor depth. The keyboard mechanisms differ, and they still deserve a trial. Equal dimensions do not mean equal key feel.

- Good
You work with phone music and a compatible wireless MIDI app
The WU-BT10 for Bluetooth audio and MIDI comes with the AP-S200. Among the PX-870's listed connections, there is no comparable built-in or included wireless route. If your phone provides backing tracks and a note-responsive app, the AP-S200 handles both tasks through its supplied adapter.

- Caution
- Casio AP-S200
- Better fit
Your lessons right now include gradual pedal control
Half-damper support is advertised on both, but the PX-870 documents continuous recognition and the AP-S200 specifies two levels plus off. If you are working on gradual pedal changes, treat this as a meaningful control difference and try the response. The half-pedal label they share would otherwise hide it.

USB audio-file recording with no laptop is mainly what you want
It comes with both. Decide on pedal response, connectivity and complete price, and don't treat recording as a feature either one has to itself.

A lesson backed by a phone can skip a separate wireless purchase
The WU-BT10 for Bluetooth audio and MIDI comes with the AP-S200. Among the PX-870's listed connections, there is no comparable built-in or included wireless route. If your phone provides backing tracks and a note-responsive app, the AP-S200 handles both tasks through its supplied adapter.

Half-pedal support differs in how fine it gets
Half-damper support is advertised on both, but the PX-870 documents continuous recognition and the AP-S200 specifies two levels plus off. If you are working on gradual pedal changes, treat this as a meaningful control difference and try the response. The half-pedal label they share would otherwise hide it.
How we worked this out
Damper response: PX-870 Continuous, AP-S200 Two levels plus off. Gradual damper support: PX-870 Yes, AP-S200 Yes. This is a conditional workflow inference drawn from these documented inputs. There is no matched performance measurement.
Option A
Casio, PX-870
PX-870
On top of a shallow cabinet with three pedals and two headphone connections, the PX-870 records audio to a USB flash drive. It lists the same depth as the PX-770, so stepping up does not mean a deeper piano body.
- Best for
- Your lessons right now include gradual pedal control
Facts we checked
- Keyboard action: Tri-sensor Scaled Hammer II
- Damper response is continuous
- Bluetooth audio reception included: No
- Bluetooth MIDI included: No
Option B
Casio, AP-S200
AP-S200
Three pedals, a two-track recorder and the Bluetooth audio and MIDI adapter all come with the AP-S200. A cabinet depth of 299 mm keeps its permanent footprint manageable in a shared room.
- Best for
- You work with phone music and a compatible wireless MIDI app
Facts we checked
- Keyboard action: Smart Scaled Hammer
- Damper response: Off, plus two levels
- Bluetooth audio reception included: Yes
- Bluetooth MIDI included: Yes
Spec by spec
Where they really differ
| Spec | Casio PX-870 | Casio AP-S200 | In practice |
|---|---|---|---|
| Keyboard mechanism | Tri-sensor Scaled Hammer II | Smart Scaled Hammer | Try out the documented mechanism before taking its name as a guarantee about feel or mechanical noise. |
| Damper response | Continuous | Two levels plus off | Different response resolutions can sit behind the term half-pedal support, and they deserve a direct trial. |
| Included Bluetooth audio reception | No | Yes | What audio reception brings in is backing music from a supported device. It does not send sound to wireless headphones. |
| Included Bluetooth MIDI | No | Yes | For a compatible note-responsive app, MIDI support is what counts. An audio-only Bluetooth connection will not do. |
| Depth before music rest | 299 mm | 299 mm | The music rest, cable route and comfortable playing clearance are all left out of bare depth. |
| Audio recording to USB memory | Yes | Yes | Live USB audio to a computer is not the same workflow as saving an audio file to a drive. |
Trade-offs
What each pick costs you
With Casio PX-870
- Recording to a USB flash drive is not the same as streaming live USB audio to a computer.
With Casio AP-S200
- On the offer you selected, verify the bench and delivery service.
Change of plan
When the answer changes
Your lessons right now include gradual pedal control
Go with Casio PX-870. Half-damper support is advertised on both, but the PX-870 documents continuous recognition and the AP-S200 specifies two levels plus off. If you are working on gradual pedal changes, treat this as a meaningful control difference and try the response. The half-pedal label they share would otherwise hide it.
You work with phone music and a compatible wireless MIDI app
Go with Casio AP-S200. The WU-BT10 for Bluetooth audio and MIDI comes with the AP-S200. Among the PX-870's listed connections, there is no comparable built-in or included wireless route. If your phone provides backing tracks and a note-responsive app, the AP-S200 handles both tasks through its supplied adapter.
You need a verified winner on mechanical key noise or on personal playing comfort
Neither model fits. Manufacturer records contain no matched test for those outcomes. Try the instruments under the conditions you intend to play in.

What this page can’t tell you
- This comparison rests on documented specifications and conditional reasoning about your setup. We have not put key feel, mechanical noise or speaker performance side by side and measured them.
- The dimensions given are for the specified body or cabinet. Allow space as well for the rest, cables, bench and player.
- Before you order, verify the exact Amazon model, color, supplied accessories, condition and delivery date.
