Eighty-eight keys, and what they weigh · review
A bundle rather than an instrument alone: the CDP-S160 with a stand, a bench, a pedal, a music stand, an adapter and headphones — and the only piano here to publish a battery life and a weight.
What it amounts to The only bundle here that includes the stand and the bench, and the only piano on this shelf whose maker publishes a weight and a battery life. Its action is published as touch response rather than as a hammer mechanism, which the closely related CDP-S110 does state.
A bundle: the CDP-S160, a pedal, a music stand, an AC adapter, headphones, a stand, a bench and a sustain pedal. The piano itself: 88 keys with touch response, ten sounds with layering, reverb and chorus, 23.1 lb, and up to 13 hours on batteries.
Two figures here exist nowhere else on this shelf, and both are the kind that normally go unpublished.
Thirteen hours of battery life. The sibling CDP-S110 publishes six AA batteries and no duration — the page for it lists battery operation as a strength and cannot say how long. Thirteen hours is a figure a reader can plan a day around.
Twenty-three point one pounds, published by Casio. No other piano on this shelf publishes a weight at all, and on an instrument that has to be carried up stairs that is the number that decides it. The product record for this listing holds 24,049 g, which is the whole bundle including the stand and the bench.
The bundle is the rest of the argument. Four pianos on this shelf include a pedal and a music stand; one includes headphones. Only this one includes a stand and a bench, and those are the two things a first piano cannot be played without — a keyboard on a dining table at the wrong height teaches posture that takes years to unlearn.
The counter-argument is on this shelf too: a cabinet piano here publishes three real pedals in a fixed cabinet, and its page notes that a cabinet does not move while you play, which no X-frame stand fully achieves.
What this listing does not publish is the action as a mechanism. It says touch response and that it accurately simulates the feel of an acoustic piano — a claim about the result. The closely related CDP-S110 on this shelf states a hammer action across all 88 keys, and that is a different sentence. The two models are near neighbors and this page will not assume they share a keybed, because the listings do not say so.
No polyphony — which no piano on this shelf publishes — and no speaker power.

| What it is | A bundle: the piano, a pedal, a music stand, an AC adapter, headphones, a stand, a bench and a sustain pedal |
|---|---|
| Keys | 88 with touch response, which Casio states simulates the feel of an acoustic piano. Not published as a hammer action — two pianos on this shelf publish one |
| Battery life | Up to 13 hours of continuous play on batteries — the only battery life published on this shelf. One other piano here publishes six AA cells and no duration |
| Weight | 23.1 lb, published by the maker — the only maker-published weight on this shelf |
| Sounds | Ten built-in, with a layer function, reverb and chorus |
| Connectivity | Headphones, audio devices and computers, over a stereo mini jack, a USB port and pedal jacks |
| Polyphony | Casio puts nothing in writing on this. No piano on this shelf publishes one |
| Action type | Casio publishes touch response and not a mechanism. The sibling CDP-S110 on this shelf publishes a hammer action across all 88 keys |
| Speakers | Casio puts nothing in writing on this. |

The listings differ. The CDP-S110, published on this shelf, states a hammer action across all 88 keys, and its page calls that the line separating a piano from a keyboard. This listing states touch response and says it accurately simulates the feel of an acoustic piano — which is a claim about the result rather than the mechanism. The two are closely related models and the published words are not the same, so this page reports both rather than assuming they share a keybed.
A stand and a bench, principally. Four of the seven pianos on this shelf include a pedal and a music stand; one other includes headphones. Only this one includes a stand and a bench — and an X-frame stand and a seat at the right height are the two things a first piano is unplayable without. The page for a cabinet piano on this shelf makes the opposite argument: a fixed cabinet does not move while you play, which no X-frame fully achieves.

88 touch-sensitive keys · 480 sounds · full accessory bundle
Not a weighted piano and not sold as one: 88 full-size touch-sensitive keys, 480 sounds, and a bundle that includes the stand, pedal, headphones, bag and adapter. The most complete box in this group.
Best for: A first instrument for someone who is not yet sure they will keep playing.
≈ $190
88 weighted keys · 10 sounds · pedal and stand included
A slim 88-key board with Casio’s Scaled Hammer Action II and, unusually at this price, the SP-3 pedal, music rest and power adapter already in the box. Ten sounds rather than hundreds — the money went into the keys.
Best for: A first weighted piano where the pedal and adapter should not be a second order.
≈ $820
88 keys · SuperNATURAL · headphone output
Roland’s entry into the FP series: 88 keys with an ivory-feel surface, the SuperNATURAL engine, and a keyboard mechanism Roland describes as quiet in itself — the detail that decides whether a flat-dweller can practice at night.
Best for: Someone who will practice mostly in headphones and wants the action to be the strong part.
≈ $500
