Our Verdict
Korg stripped away everything except what matters: three world-class grand piano samples from Italian, German, and Austrian concert grands, Korg's best RH3 action, and a 4-speaker system that fills a living room.
Pros
- • 3 grand piano sounds sampled from real Italian, German, and Austrian concert grands — extraordinary quality
- • RH3 (Real Weighted Hammer Action 3) with ivory-feel keys — Korg's flagship action
- • 40W 4-speaker system with dedicated tweeters — rich, room-filling sound
- • Bluetooth Audio + MIDI — stream music from your phone through the piano's speakers
- • Dual headphone jacks (6.3mm + 3.5mm) with spatial headphone optimization
- • Elegant furniture-style cabinet in multiple finishes — designed to live in your home
Cons
- • Only 5 sounds total — if you want organs, strings, or synths, look elsewhere
- • No lesson function, no recording, no app — zero learning aids
- • 120-note polyphony is modest for a $1,500 console (competitors offer 192–256)
- • 43kg — once placed, it's not moving
The G1B Air is an opinionated piano. With only 5 sounds, it bets everything on piano tone quality — and wins. The three grand piano voices are among the best we've heard at this price, and the 4-speaker system makes them sing. If you want versatility, buy a Yamaha CLP. If you want the purest piano experience in a console under $1,500, this is it. The Bluetooth Audio streaming is a genuine bonus that competitors at this price often lack.
Technical Deep Dive
About the Key Action
The RH3 action with ivory-feel keys is Korg's best. It delivers a satisfying, weighted touch with natural gradation from heavy bass to light treble. The ivory-textured surface provides grip even with slightly damp fingers. It's a mature, refined action that rewards expressive playing — press gently for pianissimo, dig in for fortissimo, and the keys respond faithfully.
Who Is This Piano For?
You want a beautiful piano that sounds and feels like a real instrument, and you have no interest in 200 sounds you'll never use. You're placing this in a living room or study, and you want it to look like furniture, not a gadget. Bluetooth Audio is perfect for playing along with music streaming from your phone.
