Our take on the Casio Privia PX-S3100 88-Key Digital Piano

The Casio Privia PX-S3100 is a slim 88-key digital piano with fully weighted, scaled hammer-action keys and a depth of about 9 inches, so it fits where most consoles do not. It adds a pitch bend wheel, two assignable knobs and a large library of non-piano tones and rhythms on top of the Privia piano sounds, plus Bluetooth audio and MIDI and USB. At $729.99 at B&H Photo-Video-Audio as of November 3, 2026, it sits near the low end of its recent range, which has run from roughly $700 to $850.

Pros
  • Fully weighted scaled hammer-action keys with simulated ivory and ebony feel
  • Very slim and light for an 88-key weighted piano, easy to carry and store
  • Wide sound set beyond piano, including electric pianos, organs, strings and synth tones
  • Pitch bend wheel and two assignable knobs for real-time control
  • Bluetooth audio and MIDI plus USB for apps and recording
  • Battery-capable operation for playing without an outlet
Cons
  • Speakers are modest; volume and bass are limited compared with console pianos
  • Key action is on the lighter side and some players find it less firm than rivals
  • No built-in stand or three-pedal unit; the included pedal is a simple sustain switch
  • Onboard menu system takes time to learn for deep editing

Questions and answers

Is the PX-S3100 worth it over a cheaper 88-key keyboard?
Yes, if key feel matters to you. The weighted scaled hammer action and slim body are the main reasons to pay more than for an unweighted keyboard, and the extra tones and controls add value for gigging or recording.
How does it compare with the PX-S1100?
The S3100 keeps the same slim body and key action but adds a pitch bend wheel, assignable knobs, many more tones and rhythms, and a larger display. Choose the S1100 if you only need piano sounds and want to spend less.
Does it run on batteries?
Yes. It can run on six AA batteries, which is useful for outdoor or stand-alone playing, though battery life depends on volume and use.
What is in the box?
You get the piano, a sustain pedal, a music rest and a power supply. A stand and a three-pedal unit are sold separately.
Can I use it with a phone or computer?
Yes. It supports Bluetooth audio and MIDI and has USB, so it works with piano apps, DAWs and MIDI software.
When is the price lowest?
It has sold around $700 during sales, and $729.99 at B&H Photo-Video-Audio as of November 3, 2026 is already near the low end of its recent range. Waiting for a holiday sale may save little.
