Main trade-off
Casio PX-870
The cabinet weighs 34.3 kg before considering packaging or delivery access.
Head-to-head
Casio PX-870 vs Casio AP-S200: AP-S200 includes wireless connections, PX870 continuously detects pedaling
The short answer
Choose the AP-S200 for phone music and wireless MIDI without buying an adapter separately. Choose the PX-870 when continuously detected damper response is the stronger priority.
Before you choose
The reasoning and the trade-offs
A replacement piano can keep the same cabinet footprint
Both list 1393 mm width and 299 mm depth. If that rectangle already fits your room, changing between these models does not require more listed floor depth. Their different keyboard mechanisms still deserve a trial. Equal dimensions do not establish equal key feel.
What this is based on
PX-870: Listed width 1393 mm. AP-S200: Listed width 1393 mm. PX-870: Depth before music rest 299 mm. AP-S200: Depth before music rest 299 mm. PX-870: Keyboard mechanism Tri-sensor Scaled Hammer II. AP-S200: Keyboard mechanism Smart Scaled Hammer. Conditional workflow inference from these documented inputs. No matched performance measurement.
Main trade-off
Casio AP-S200
The damper uses two levels plus off, rather than the PX-870's continuously detected response.

Winner by situation
Start with what you need it to do
You are choosing for an already measured console space
Both list 1393 mm width and 299 mm depth. If that rectangle already fits your room, changing between these models does not require more listed floor depth. Their different keyboard mechanisms still deserve a trial. Equal dimensions do not establish equal key feel.

- Good
- Casio AP-S200
- Good
You use phone music and a compatible wireless MIDI app
AP-S200 includes the WU-BT10 for Bluetooth audio and MIDI. PX-870 has no comparable built-in or included wireless route in its listed connections. If the phone supplies backing tracks and a note-responsive app, the AP-S200 supports both tasks with its supplied adapter.
- Casio PX-870
- Caution
- Casio AP-S200
- Better fit
Gradual pedal control is part of your current lessons
Both advertise half-damper support, but PX-870 documents continuous recognition while AP-S200 specifies two levels plus off. A player working on gradual pedal changes should treat this as a meaningful control difference and try the response. The shared half-pedal label would otherwise hide it.

You mainly want USB audio-file recording without a laptop
Both provide it. Choose using pedal response, connectivity and complete price rather than treating recording as an exclusive feature.

Half-pedal support has different levels of detail
Both advertise half-damper support, but PX-870 documents continuous recognition while AP-S200 specifies two levels plus off. A player working on gradual pedal changes should treat this as a meaningful control difference and try the response. The shared half-pedal label would otherwise hide it.
How we reached this conclusion
PX-870: Damper response Continuous. AP-S200: Damper response Two levels plus off. PX-870: Gradual damper support Yes. AP-S200: Gradual damper support Yes. Conditional workflow inference from these documented inputs. No matched performance measurement.
Choice A
Casio, PX-870
PX-870
The PX-870 adds USB flash-drive audio recording to a shallow cabinet with three pedals and two headphone connections. Its listed depth matches the PX-770, so the upgrade does not require a deeper piano body.
- Best matched use
- Gradual pedal control is part of your current lessons
Checked facts
- Keyboard mechanism: Tri-sensor Scaled Hammer II
- Damper response: Continuous
- Included Bluetooth audio reception: No
- Included Bluetooth MIDI: No
Choice B
Casio, AP-S200
AP-S200
The AP-S200 includes its Bluetooth audio and MIDI adapter, a two-track recorder and three pedals. Its 299 mm cabinet depth keeps the permanent footprint manageable in a shared room.
- Best matched use
- You use phone music and a compatible wireless MIDI app
Checked facts
- Keyboard mechanism: Smart Scaled Hammer
- Damper response: Two levels plus off
- Included Bluetooth audio reception: Yes
- Included Bluetooth MIDI: Yes
Meaningful differences
What changes the fit
| What changes | Casio PX-870 | Casio AP-S200 | Why it matters |
|---|---|---|---|
| Keyboard mechanism | Tri-sensor Scaled Hammer II | Smart Scaled Hammer | Try the documented mechanism before treating its name as a guarantee about feel or mechanical noise. |
| Damper response | Continuous | Two levels plus off | Half-pedal support can describe different response resolutions that deserve a direct trial. |
| Included Bluetooth audio reception | No | Yes | Audio reception carries backing music from a supported device, not sound to wireless headphones. |
| Included Bluetooth MIDI | No | Yes | A compatible note-responsive app needs MIDI support rather than an audio-only Bluetooth connection. |
| Depth before music rest | 299 mm | 299 mm | Bare depth excludes the music rest, cable route and comfortable playing clearance. |
| Audio recording to USB memory | Yes | Yes | Saving an audio file to a drive is a different workflow from live USB audio to a computer. |
What you give up
Every choice has a cost
If you choose Casio PX-870
- USB flash-drive recording is a different route from sending live USB audio to a computer.
If you choose Casio AP-S200
- Check the bench and delivery service on the selected offer.
Recommendation switch
The decision flips if...
Gradual pedal control is part of your current lessons
Choose Casio PX-870. Both advertise half-damper support, but PX-870 documents continuous recognition while AP-S200 specifies two levels plus off. A player working on gradual pedal changes should treat this as a meaningful control difference and try the response. The shared half-pedal label would otherwise hide it.
You use phone music and a compatible wireless MIDI app
Choose Casio AP-S200. AP-S200 includes the WU-BT10 for Bluetooth audio and MIDI. PX-870 has no comparable built-in or included wireless route in its listed connections. If the phone supplies backing tracks and a note-responsive app, the AP-S200 supports both tasks with its supplied adapter.
You require a verified winner for mechanical key noise or personal playing comfort
Choose neither. The manufacturer records do not provide a matched test for those outcomes. Try the instruments in your intended conditions.
What matters in practice
Before you choose
What this comparison cannot tell you
- The comparison uses documented specifications and conditional setup reasoning. We have not measured key feel, mechanical noise or speaker performance side by side.
- Dimensions describe the specified body or cabinet. Leave room for the rest, cables, bench and player.
- Check the exact Amazon model, color, supplied accessories, condition and delivery date before ordering.
