Main trade-off
Yamaha P-225
The music rest takes its depth to 362 mm. A body that fits a shallow desk does not establish that the complete playing setup fits.
Head-to-head
Yamaha P-225 vs Korg B2+: Yamaha adds shared headphones and saves 64 mm depth, both record USB audio
The short answer
Choose P-225 if two people need headphones together or the piano shares a shallow desk. It has two headphone sockets, separate line outputs and a body that is 64 mm shallower. Choose B2+ if you want a small sound selection, wired Audio In for a phone or player, and one headphone connection is enough. Both carry piano audio over USB, so you do not need to upgrade to Yamaha just to record into a compatible computer.
Before you choose
The reasoning and the trade-offs
Try the piano sound you will use, rather than its headline note count
A returning player may use the sustain pedal across fuller chords than a beginner. B2+ is advertised with 120-note maximum polyphony, but its manual explains that most sounds use two samples per note and allow 60 notes. The three Italian piano sounds use three samples and allow 40. The 120 figure applies to stage electric piano. If sustained acoustic-piano passages are important, try those actual sounds before choosing from the headline. Yamaha states a 192-note maximum, but we do not turn the different engines into a measured ratio or promise that a particular passage will lose notes on Korg.
What this is based on
Korg manual troubleshooting explains sample consumption and the 40, 60 and 120-note cases. Yamaha states a 192-note maximum without an equivalent per-voice accounting table here. No measured note-stealing or sound-quality claim.
Main trade-off
Korg B2+
Its single Phones/Line Out socket is shared by headphone and analog-output duties. Two people listening on headphones need additional suitable equipment.
Yamaha P-225
- Choose it for
- You and a learner need separate headphone connections during the same practice session.
- The 272 mm bare-body depth fits your space better than B2+ at 336 mm. Allow 362 mm for Yamaha with its music rest.
- Main trade-off
- The music rest takes its depth to 362 mm. A body that fits a shallow desk does not establish that the complete playing setup fits.
Korg B2+
- Choose it for
- You want to play wired phone or player audio through the piano’s Audio In, and one headphone socket is enough.
- Twelve sounds cover your practice, and you will use the documented USB-audio route when recording to a compatible device.

About this comparison
Compare P-225 and B2+ for parent-and-child practice, a desk shared with work and recording. See which sockets and dimensions change the daily setup.
These are 88-key weighted home pianos with speakers, USB audio and a supplied basic pedal. A learner who wants to record and share practice has good reason to compare them without moving into a furniture-style piano.

What matters in practice
The differences that matter
Try the piano sound you will use, rather than its headline note count
A returning player may use the sustain pedal across fuller chords than a beginner. B2+ is advertised with 120-note maximum polyphony, but its manual explains that most sounds use two samples per note and allow 60 notes. The three Italian piano sounds use three samples and allow 40. The 120 figure applies to stage electric piano. If sustained acoustic-piano passages are important, try those actual sounds before choosing from the headline. Yamaha states a 192-note maximum, but we do not turn the different engines into a measured ratio or promise that a particular passage will lose notes on Korg.
How we reached this conclusion
Korg manual troubleshooting explains sample consumption and the 40, 60 and 120-note cases. Yamaha states a 192-note maximum without an equivalent per-voice accounting table here. No measured note-stealing or sound-quality claim.
Sharing the keys is only half of a quiet lesson
Both can divide the keyboard for a teacher and learner. If that lesson happens while someone else works or sleeps, two headphone connections become useful too. P-225 lets both people plug in directly. B2+ has one shared headphone and line-output socket, so budget for a suitable splitter or headphone amplifier if two people need to listen. Do not assume either arrangement gives each listener independent volume control. Headphones also leave physical key noise, so this is a wiring advantage rather than a promise of silent practice.
How we reached this conclusion
Duo or Partner Mode plus documented headphone-port counts. The two-listener setup is a conditional household need. No key-noise measurement or independent headphone-volume claim.
The shallow-body advantage can disappear when the music comes out
Yamaha’s body is 64 mm shallower than Korg’s, about 2.5 inches. That helps when the piano is stored or used without its rest. P-225 reaches 362 mm deep with the music rest, though, so a 14-inch surface is shorter than that stated dimension even before cable access. B2+ is 336 mm deep before its stand is added, with no equivalent ready-to-play figure used here. If printed music is essential, check the complete setup rather than treating the bare-body winner as a guaranteed desk fit.
How we reached this conclusion
336 minus 272 = 64 mm. 64 / 25.4 = 2.52 inches. Yamaha rest depth 362 / 25.4 = 14.25 inches. Korg rest depth is not inferred from its bare dimensions.
Keep the existing speakers without using up the listening connection
If this piano doubles as a practice instrument and a keyboard plugged into powered speakers, P-225 gives those jobs separate sockets. B2+ sends analog audio from the same socket used for headphones. That can mean unplugging one setup before using the other, or adding an appropriate audio-routing device. For recording into a computer, both already provide USB audio. Decide whether your repeated inconvenience is switching analog cables or recording the piano. Yamaha fixes the first more directly, while USB recording alone is no reason to rule Korg out.
How we reached this conclusion
P-225 separate AUX OUT and headphone connections compared with B2+ combined Phones/Line Out. USB audio is documented for both. No simultaneous output behavior or speaker-mute setting is assumed.

Meaningful differences
What changes the fit
| What changes | Yamaha P-225 | Korg B2+ | Why it matters |
|---|---|---|---|
| Headphone connections | Two standard stereo headphone sockets | One shared Phones/Line Out socket | Two listeners can plug directly into Yamaha. Korg needs a suitable splitter or headphone distribution setup. |
| External speakers | Separate L/L+R and R line outputs | Uses Phones/Line Out | On Yamaha, analog speaker wiring does not occupy a headphone socket. |
| Bare body depth | 272 mm | 336 mm, excluding music stand | The 64 mm difference can matter on a desk, but neither number includes all working clearance. |
| Phone or player input | Bluetooth audio on US model, plus USB audio | Wired Audio In, plus USB audio | Choose the connection the household’s actual playback device can supply. |
| Computer audio recording | USB audio interface | USB-C carries audio and MIDI | Both can send their sound to a compatible device. A connector change alone is not a sound-quality upgrade. |
| Learning together | Duo mode and 24 voices | Partner Mode and 12 sounds | Both divide the keyboard for shared practice. Their headphone wiring differs. |
| Sustained-note limits | 192-note stated maximum | 120 maximum, 60 for most sounds and 40 for the three Italian piano sounds | Korg’s headline maximum does not apply to all its piano sounds. Do not turn the two brands’ maxima into a guaranteed performance ratio. |
What you give up
Every choice has a cost
If you choose Yamaha P-225
- Its documented phone-playback routes are Bluetooth and USB audio. Check the source device if your existing player only supplies analog audio.
If you choose Korg B2+
- Its 120-note headline applies to stage electric piano. The manual lists lower limits for its acoustic-piano sounds, so test the tone you will actually use.
Recommendation switch
The decision flips if...
Two direct headphone connections settle the decision
Choose Yamaha P-225. Yamaha supplies them alongside separate analog line outputs.
A wired analog input for a phone or player is essential
Choose Korg B2+. Korg provides Audio In, subject to the source device having a suitable output.
What matters in practice
Before you choose
You want the piano to be easy to share, yet it has to fit on a desk used for other things. The smaller bare body and separate listening connections matter more here than a larger speaker-power number.
What this comparison cannot tell you
- No measured key-action, sound-quality, loudness or latency ranking is claimed. Speaker wattage alone does not settle those questions.
- Body-depth comparisons exclude the rest unless explicitly stated.
