Pros & Cons
👍 Pros
- The NH4 hammer-weighted keybed with graded weight across the register gives practice sessions the physical resistance needed to build accurate technique.
- At 25 pounds and 4.61 inches thick, it travels to lessons, rehearsals, or small gigs without requiring a dedicated vehicle or dolly.
- USB Audio and MIDI over a single cable eliminates the need for a separate audio interface for basic DAW recording sessions.
- The German and Italian piano voicings hold up well in headphone practice — rich, layered tone that doesn't fatigue over long sessions.
- Six-AA-battery operation means you can practice in spaces with no mains power — a genuine asset for outdoor events or locations with limited outlets.
👎 Cons
- 120-voice polyphony, while adequate for most playing, can thin out during dense, sustain-heavy passages in more complex arrangements.
- The included sustain pedal is a basic on/off switch — players working on expressive classical repertoire will want to budget for a half-pedaling compatible pedal separately.
- The built-in speaker system, while convenient, lacks the low-end resonance of larger piano cabinets — orchestral and bass-register playing sounds more accurate through headphones or monitors.
- With only 12 sounds, players who need broad sonic variety for production, gigging, or classroom use will find the palette limiting.
- The NH4 action, while weighted, lacks the escapement simulation found on Korg's higher-tier keybeds — advanced players will feel the difference in repetition speed on fast passages.
Frequently Asked Questions
How realistic does the NH4 weighted action feel for players transitioning from an acoustic piano?
The NH4 (Natural Weighted Hammer Action) is Korg's entry-level hammer-action keybed, and it delivers genuine key weight graduation — heavier in the bass register, lighter in the treble — which is the defining physical characteristic of an acoustic piano. Players coming from a real upright or grand will notice it lacks the nuanced escapement feel of higher-end hammer actions, but for practice and performance at this price point, the grading is convincing enough to build proper technique.
Can I use the B2WH with a DAW for MIDI recording, or does it only transmit MIDI — not audio?
The B2WH's USB connection carries both USB Audio and USB MIDI simultaneously. You can record its internal sounds directly into a DAW as audio without an external audio interface, and you can also use it as a MIDI controller to trigger software instruments. Both modes work concurrently over a single USB cable.
Does the battery-powered operation support all features, or are some functions disabled without mains power?
All 12 sounds, the built-in speakers, and full keyboard operation run on six AA batteries. Battery life will vary with speaker volume — playing at low levels extends runtime considerably. The USB Audio/MIDI function requires a USB connection to a host device and does not operate in standalone battery mode.
What's the polyphony count, and will I hit the ceiling playing layered sounds or sustain-heavy passages?
The B2WH offers 120-voice polyphony. For a piano with 88 keys, this is sufficient for most playing styles, including sustained passages with the damper pedal held. Very dense orchestral playing with layered sounds can approach the ceiling, but for standard piano repertoire and practice, note dropout is not a practical concern.
Is the included sustain pedal a simple on/off switch, or does it support half-pedaling?
The included sustain pedal is a standard on/off switch-type pedal. Half-pedaling — the gradual partial damping used in expressive acoustic piano technique — is not supported by the bundled accessory, though the B2WH's damper input may respond to compatible continuous controller pedals sold separately.
