Our Verdict
A pure pianist's tool — no speakers, no fluff. The D1 puts Korg's flagship RH3 action and ivory-feel keys into a flat-top body designed for headphones or external amplification.
Pros
- • RH3 (Real Weighted Hammer Action 3) — Korg's best keybed, same as the $1,500 G1B Air
- • Ivory-feel key surface for better grip and moisture absorption
- • 30 sounds including quality grand pianos, electric pianos, and organs
- • Line out jacks for connecting to studio monitors, PA systems, or amplifiers
- • USB MIDI for DAW integration — great as a studio controller
- • Slim 100mm profile and flat-top design — fits neatly on any desk or stand
Cons
- • No built-in speakers — you must use headphones, an amplifier, or powered monitors
- • 16kg is heavy for a portable — not something you'd carry on the train
- • No Bluetooth, no lesson function, no recording, no app — zero learning features
- • Single 6.3mm headphone jack — no sharing practice sessions
The D1 is an unusual product — a speakerless portable that prioritizes touch quality above everything else. If you need built-in speakers, look elsewhere. But if you have headphones or an amp and you want the most authentic piano feel at $600, the D1 delivers Korg's flagship action at a mid-range price. It's a favorite among pianists who already own a keyboard and want something better to practice on.
Technical Deep Dive
About the Key Action
The RH3 is Korg's top-tier action, and it shows. The keys have genuine heft in the bass register that gradually lightens toward the treble, closely mimicking a grand piano's hammer weight. The ivory-feel surface prevents slipping during fast passages. This is a serious action — noticeably better than the NH action found on cheaper Korgs, and competitive with Yamaha's GHS and Roland's PHA-4 Standard.
Who Is This Piano For?
You already know how to play, and you want the best possible key feel at $600. Maybe you practice at home with headphones plugged into a quality amp, or you need a reliable stage piano for weekend gigs. You don't need lessons or Bluetooth — you need keys that feel right under your fingers.
