Quick answer: For most buyers, the Korg B2SP (around $580-650 at US retailers) is the best Korg digital piano — it’s the same NH-action B2 piano as the base model, but its bundled 3-pedal unit supports half-pedaling, something the stand-less B2’s included pedal doesn’t do without buying Korg’s optional PU-2 unit separately. Budget shoppers can start with the plain B2 (around $500-600), and players who want a furniture-style console with Bluetooth audio streaming should look at the C1 Air (around $1,700-1,800) or the LP-380 (around $1,300).
Korg currently sells four digital pianos most US shoppers run into: the entry-level B2, the B2SP bundle built around the same instrument, the compact console C1 Air, and the furniture-style LP-380. According to Korg’s own US specification page, the jump from B2 to B2SP buys more than a stand — it changes what the included pedal can do. We ranked the lineup by what actually changes as price climbs.

1. Korg B2SP — Best Overall
Korg B2SP
- Same NH (Natural Weighted Hammer Action) keyboard and 120-note polyphony as the base B2.
- Bundled wooden stand plus a 3-pedal unit (damper, soft, sostenuto) that supports half-pedaling out of the box.
- 15W x 2 speakers, the same sound engine and 12 built-in sounds as the standalone B2.

The B2SP is our top Korg pick because the pedal unit it bundles genuinely does more than the plain B2’s included pedal: Korg’s own US spec page for the B2 lists half-pedaling as requiring the optional PU-2 unit, sold separately, while the B2SP’s included 3-pedal unit supports half-pedaling without any add-on purchase. For only a modest premium over the stand-less B2, you’re not just buying furniture — you’re buying a pedal feature the cheaper box doesn’t include.
2. Korg B2 — Best Budget
Korg B2
- Same NH hammer-action keyboard and 120-note polyphony as the B2SP — no difference in the piano itself.
- Ships with a basic damper pedal only; Korg's spec sheet lists half-pedaling as requiring the optional PU-2 unit.
- No included stand — budget for a separate X-stand or bench if you don't already have a surface for it.
The B2 is the right pick if you already own a stand or keyboard bench and just want the instrument itself. Just go in aware that “digital piano” on the box doesn’t mean full pedal functionality is included — the stock damper pedal here is on/off only, per Korg’s own specifications, and if you later decide you want half-pedaling for sustain-heavy playing, the PU-2 add-on narrows (and can erase) the savings versus just buying the B2SP up front. See our best sustain pedal guide if you’re shopping pedals separately either way.
3. Korg C1 Air — Best Bluetooth Console
Korg C1 Air
- RH3 hammer action — heavier feel in the low register, lighter in the high register, like an acoustic grand.
- 2 x 10cm stereo speakers at 50W combined, with 30 onboard sounds including German and Japanese grand piano samples.
- Bluetooth audio receiver — streams music or an app's audio into the piano's own speakers so you can play along.
Don’t assume “Bluetooth” here means what it means on some other brands’ lineups. Retailer listings describe the C1 Air’s Bluetooth as audio-in only — it receives a stream from your phone or tablet so the piano’s speakers play it back, which is useful for practicing along with a backing track, but it is not a MIDI link for a lesson app or DAW. That’s the mirror image of the naming trap we found on Roland’s FP-10, which has Bluetooth MIDI but no audio streaming — see our FP-10 vs FP-30X comparison for that version of the same “check which direction Bluetooth goes” problem on a different brand.
4. Korg LP-380 — Best Traditional Console
Korg LP-380
- RH3 hammer-action keyboard and 120-note polyphony in a furniture-style cabinet with 3 pedals built in.
- Two 22W amplifiers (44W total) driving built-in speakers — close to triple the B2SP's combined output.
- 30 onboard sounds, including acoustic and vintage electric piano voices, with USB Audio/MIDI connectivity.
The LP-380 is Korg’s answer for buyers who want a piece of living-room furniture rather than a portable board on a stand — full-width cabinet, built-in 3-pedal unit, and enough amplifier headroom that the speakers won’t be the limiting factor. It costs roughly twice the B2SP, but the gap buys a different action generation (RH3 vs NH), nearly 3x the speaker wattage, and a cabinet that doesn’t need a separate stand purchase.
How Korg’s lineup actually differs
- B-series (portable). The B2 and B2SP share the exact same piano — same NH action, same 120-note polyphony, same 12 sounds. The only difference is the bundled stand and, more importantly, a pedal unit that actually unlocks half-pedaling the base model’s included pedal can’t do.
- C1 Air and LP-380 (console). Both move up to the RH3 action and dramatically more speaker power, but only the C1 Air adds Bluetooth — and that Bluetooth streams audio in, not MIDI out, the opposite of what you might expect from other brands’ “Bluetooth” spec-sheet line.
- Across the board, polyphony tops out at 120-note on the models that list a figure — lower than some rival brands’ 192-256-note flagships, worth factoring in if you plan to layer sustain-heavy chords. If you’re still deciding whether you need a weighted action at all before committing to any brand, see our digital piano vs keyboard comparison.
For a cross-brand view at the entry price point, our best digital piano guide covers Yamaha, Roland, and Casio alternatives in the same range as the B2 and B2SP. And if half-pedaling and pedal compatibility matter to your decision, our best sustain pedal guide covers which separate pedals actually support it.
The bottom line
For most buyers, the Korg B2SP is the best Korg digital piano — the same piano as the base B2, plus a stand and a pedal unit that actually adds half-pedaling capability, for only a modest premium. Step up to the C1 Air or LP-380 only once you specifically want console styling and more amplifier power than the portable B-series offers.
