The Casio CDP-S160 (~$499) is my top recommendation for students on a budget. Its Scaled Hammer Action is lighter than most competitors – and that is a good thing. After 6+ years of putting students in front of this action, I’ve watched them develop clean, controlled technique that transfers smoothly to acoustic pianos. The even dynamic response is what seals it: when a student plays quietly, it sounds quiet. That kind of feedback is surprisingly rare at this price.

There’s a version of this review that spends a lot of time on specs. I’d rather skip to the part that matters: I’ve had students practice on the CDP-S160 (and its predecessor) for over six years now, and the results speak for themselves. These students transition to acoustic pianos without the awkward adjustment period I see from students who trained on inferior actions. That’s the bottom line.

Casio doesn’t get the credit it deserves in the piano world. The CDP-S160 is a serious student instrument at a price that makes it accessible to almost anyone starting out.

Sound Quality

The CDP-S160 has 10 voices, and honestly, most students will use one – the Grand Piano. It’s a clean, clear sample that sits in the mix well and doesn’t fatigue the ears during long practice sessions. It’s not going to compete with Yamaha’s CFX sampling in the P-225, but it doesn’t need to. For the first one to three years of study, what matters is that the piano sound is convincing enough to motivate daily practice. The CDP-S160 clears that bar comfortably.

The electric piano and organ patches are functional. Beginners exploring non-piano sounds will find them adequate. The string and vibraphone voices round out the set, though none of them are particularly inspiring. This is a piano first and foremost.

What does stand out is the dynamic response. The voice samples react proportionally to how hard you press the keys – soft playing sounds genuinely soft, and the full-force notes have real presence. I’ve tested budget pianos where the dynamics feel random or compressed into a narrow band. The CDP-S160 doesn’t have that problem. For a student learning to shape phrases and control their touch, that even response is genuinely valuable.

At 64-note polyphony, you will eventually hit limits. Heavy use of the sustain pedal with dense chords can cause the oldest notes to drop out. For beginners and early-intermediate students working through standard repertoire, this rarely comes up. But if you’re working on late-intermediate pieces with a lot of sustained harmony, you’ll notice it. It’s the most meaningful technical limitation of the instrument.

Key Action

The Scaled Hammer Action is the CDP-S160’s defining feature – and the thing I get asked about most when I recommend it.

Yes, it’s lighter than the key action on a Roland FP-10 or a typical acoustic upright. When people hear that, they often assume it means “less realistic” or “worse for technique.” My experience teaching on both tells a different story.

A lighter, responsive action teaches dynamic control precisely because it responds so cleanly to what the student does. There’s nowhere to hide. Every nuance of touch shows up in the sound. Students who train on the CDP-S160’s action learn to produce gradations of sound because the instrument rewards them for it. When they eventually sit at an acoustic piano, they have the sensitivity to work with whatever action weight they encounter.

Compare that to a student who trained on a stiff, heavy action. They’ve been compensating with arm weight and brute force. Sit them at a responsive acoustic and they overshoot constantly.

The scaling is proper: bass keys are heavier than treble keys, matching the graduated resistance of an acoustic piano. The simulated ivory and ebony key surfaces add grip without being slippery or sticky. Over years of daily practice, that texture matters, especially for younger students with smaller hands.

The one thing the CDP-S160 doesn’t have is escapement simulation – the subtle mechanical “notch” you feel when pressing keys very slowly on a grand piano. The Roland FP-10 at the same price has it. If you’re specifically training for classical repertoire and want every nuance of acoustic piano feedback, the FP-10 is worth considering. But for the vast majority of students, the CDP-S160’s action is more than sufficient.

Features and Connectivity

• Driverless USB-MIDI: Plug it into any computer, tablet, or phone and it works immediately – no drivers, no setup. This matters more than it sounds. Parents don’t want to troubleshoot software before a practice session.
• Casio Music Space App: Casio’s free companion app gives you access to settings, voice selection, and interactive lesson features. It’s solid – not quite at Yamaha’s Smart Pianist level, but genuinely useful for beginners working with play-along content.
• Duet Mode: Splits the keyboard so teacher and student can play the same octave range side by side. I use this regularly in lessons. It’s one of those features that sounds gimmicky until you actually teach with it.
• Battery Power: Six AA batteries or the included AC adapter. The battery option is a real practical advantage – you can set it up in any room, on any surface, without running cables. For families who don’t have a dedicated practice space, this flexibility gets used.
• Headphone Jack: One standard 1/4-inch output. Works with any headphones or adapter. Fine for solo practice.

The notable absence is Bluetooth. There’s no Bluetooth audio or MIDI – if you want to connect wirelessly to apps like Flowkey or Simply Piano, you’ll need a USB cable. For students who work heavily with apps, that’s a real inconvenience. The Roland FP-10 has Bluetooth MIDI at the same price if wireless connectivity is a priority.

There are no built-in lesson features beyond what the app provides, no rhythm accompaniment, and no recording functions. None of these omissions matter for a student focused on learning to play the piano – but if you want a more feature-packed instrument, look at the Casio PX-S1100 (~$649) or step up in budget.

Build Quality and Design

The CDP-S160 is remarkably slim and light. At 23.1 lbs, it’s easy to move, easy to store, and – with the battery option – easy to place anywhere. Families with limited space appreciate this more than any spec on a sheet.

Build quality is solid. The chassis doesn’t flex under normal playing pressure, the buttons feel durable, and the key surfaces have held up well across multiple years of student use in my teaching experience. This is not a toy.

The speaker system is modest. For quiet practice in a bedroom or small living room, it’s perfectly adequate. If you want to fill a larger space or play along with recordings without headphones, you’ll find it underwhelming. An external Bluetooth speaker or wired amplifier solves the problem if needed.

The slim profile also means there’s no music rest included in the base configuration – you’ll want a separate stand with a music desk, or a dedicated keyboard stand that includes one. Factor that into your total budget if you don’t already have a setup.

Who It’s For

• Beginners and early-intermediate students. This is what the piano was designed for, and it excels at it. The action, the dynamic response, and the reliability make it ideal for the first two to four years of study.
• Parents buying for kids. The light weight, battery power, and driverless USB connectivity make it the most practical option in this price range for a household that hasn’t yet built a dedicated piano space.
• Budget-conscious buyers who won’t compromise on touch. The action is the most important thing about a student piano. The CDP-S160’s Scaled Hammer Action is the best-value option in this price tier.
• Teachers looking for a secondary studio instrument. Affordable, reliable, easy to move – useful to have around.

Who Should Skip It

• If wireless app connectivity is important, the Roland FP-10 (~$499) has Bluetooth MIDI and Roland’s Piano Partner 2 app ecosystem.
• If you want escapement simulation for classical training, the FP-10’s PHA-4 action is the best in class at this price – though note its action runs on the heavier side.
• If your budget is tighter, the Yamaha P71 (~$429) is an Amazon exclusive that’s identical to the P-45. Its compressed dynamic range actually has a teaching benefit: it forces students to exaggerate their touch, which builds control. A legitimate option $70 cheaper.
• If you’re an intermediate or advanced player, step up to the Yamaha P-225 (~$699) for the CFX sound engine and a more expressive action.
