The catch
Yamaha P-225
With the music rest, depth reaches 362 mm. A body that suits a shallow desk says nothing certain about whether the full playing setup will.
Side by side
Yamaha P-225 vs Korg B2+ for shared practice and desk space: Both record USB audio, and Yamaha adds shared headphones and saves 64 mm depth
Quick verdict
P-225 is the pick if two people need headphones together or the piano has to share a shallow desk. It offers two headphone sockets, separate line outputs and a body 64 mm shallower. B2+ is the pick if a small sound selection and wired Audio In for a phone or player appeal to you, and one headphone connection is enough. Piano audio travels over USB on both, so you do not have to move up to Yamaha just to record into a compatible computer.
Before you buy
Why, and what it costs you
Judge by the piano sound you will play and look past the headline note count
Someone returning to piano may hold the sustain pedal through fuller chords than a beginner does. The B2+ is advertised with 120-note maximum polyphony, yet its manual explains that most sounds use two samples per note and so allow 60 notes. The three Italian piano sounds use three samples and allow 40. Only the stage electric piano gets the 120 figure. If long, sustained acoustic-piano passages matter to you, play those exact sounds before you decide based on the headline. Yamaha states a 192-note maximum. We don’t convert the two different engines into a measured ratio, and we make no promise that any particular passage will drop notes on Korg.
Where this comes from
The troubleshooting section of Korg’s manual covers how samples are consumed and the 40, 60 and 120-note cases. For Yamaha, a 192-note maximum is stated, with no comparable per-voice accounting table here. Nothing is claimed about measured note-stealing or sound quality.
The catch
Korg B2+
One Phones/Line Out socket handles both headphone and analog-output duty. For two people to listen on headphones, you need extra suitable equipment.
Yamaha P-225
- Why pick it
- During the same practice session, you and a learner each need your own headphone connection.
- Your space suits the 272 mm bare-body depth better than the 336 mm of B2+. With its music rest, allow 362 mm for Yamaha.
- The catch
- With the music rest, depth reaches 362 mm. A body that suits a shallow desk says nothing certain about whether the full playing setup will.
Korg B2+
- Why pick it
- You want wired phone or player audio played through the piano’s Audio In, and one headphone socket is enough for you.
- Twelve sounds are enough for your practice, and you will use the documented USB-audio route to record to a compatible device.

What this page compares
Looking at the P-225 and B2+ for practice with your child, a desk you also work at and recording? See which sockets and dimensions change your daily setup.
Each is a weighted 88-key home piano with speakers, USB audio and a basic pedal in the box. A learner who wants to record and share practice has good reason to weigh them against each other without stepping up to a furniture-style piano.

How we worked this out
The troubleshooting section of Korg’s manual covers how samples are consumed and the 40, 60 and 120-note cases. For Yamaha, a 192-note maximum is stated, with no comparable per-voice accounting table here. Nothing is claimed about measured note-stealing or sound quality.
Splitting the keys covers just half of a quiet lesson
Either piano can divide the keyboard between a teacher and a learner. When the lesson runs while someone else is working or asleep, two headphone connections help as well. On the P-225, both people plug in directly. The B2+ has a single socket shared by headphones and line output, so if two people need to listen, budget for a suitable splitter or headphone amplifier. Neither setup should be assumed to give each listener their own volume control. Keys still make noise under headphones, which makes this a wiring advantage and not a promise of silent practice.
How we worked this out
Based on Duo or Partner Mode and the documented headphone-port counts. Two listeners is a conditional household need. No key-noise measurement or independent headphone-volume claim is made.
The advantage of a shallow body can vanish once the music is out on the rest
Compared with Korg, Yamaha’s body is 64 mm shallower, about 2.5 inches. That counts for something when the piano is put away or played without its rest. With the music rest, however, the P-225 reaches 362 mm deep, so a 14-inch surface is shorter than that stated dimension before cables even come into it. The B2+ is 336 mm deep ahead of its stand, and no comparable ready-to-play figure is used here. When printed music is a must, check the whole setup. The winner on bare-body depth is not guaranteed to fit a desk.
How we worked this out
336 minus 272 = 64 mm, and 64 / 25.4 = 2.52 inches. Yamaha’s depth with the rest is 362 / 25.4 = 14.25 inches. Korg’s depth with its rest is not inferred from bare dimensions.
Run your existing speakers without tying up the listening connection
Say the piano is a practice instrument and also a keyboard feeding powered speakers. The P-225 gives those jobs their own sockets. The B2+ sends analog audio out of the very socket used for headphones, which may mean unplugging one setup to use the other or adding a suitable audio-routing device. Recording into a computer is already covered on both, since both provide USB audio. So ask which repeated hassle bothers you more, switching analog cables or recording the piano. Yamaha deals with the first one more directly, and USB recording by itself is no reason to rule Korg out.
How we worked this out
The P-225 has separate AUX OUT and headphone connections, while the B2+ combines them in one Phones/Line Out. USB audio is documented on both. Nothing is assumed about simultaneous output behavior or a speaker-mute setting.

Spec by spec
Where they really differ
| Spec | Yamaha P-225 | Korg B2+ | In practice |
|---|---|---|---|
| Headphone connections | Two standard stereo headphone sockets | One shared Phones/Line Out socket | On Yamaha, two listeners plug in directly. On Korg, you need a suitable splitter or headphone distribution setup. |
| External speakers | Separate L/L+R and R line outputs | Uses Phones/Line Out | Yamaha’s analog speaker wiring doesn’t use up a headphone socket. |
| Bare body depth | 272 mm | 336 mm, excluding music stand | A 64 mm difference can count on a desk, yet neither figure accounts for all the working clearance. |
| Phone or player input | Bluetooth audio on US model, plus USB audio | Wired Audio In, plus USB audio | What the household’s playback device can supply should decide the connection. |
| Computer audio recording | USB audio interface | USB-C carries audio and MIDI | Either piano can send its sound to a compatible device. Swapping connectors by itself won’t improve sound quality. |
| Learning together | Duo mode and 24 voices | Partner Mode and 12 sounds | For shared practice, each can split the keyboard. Where they differ is headphone wiring. |
| Sustained-note limits | 192-note stated maximum | 120 maximum, 60 for most sounds and 40 for the three Italian piano sounds | Not every Korg piano sound gets its headline maximum. Don’t read the two brands’ maximums as a guaranteed performance ratio. |
Trade-offs
What each pick costs you
With Yamaha P-225
- Bluetooth and USB audio are the documented ways to play from a phone. If your current player only offers analog audio, check the source device.
With Korg B2+
- The 120-note headline holds for stage electric piano only. Its manual gives lower limits for the acoustic-piano sounds, so try the tone you will really play.
Change of plan
When the answer changes
The decision comes down to having two direct headphone connections
Go with Yamaha P-225. Yamaha provides them, and adds separate analog line outputs.
You can’t do without a wired analog input for a phone or player
Go with Korg B2+. Korg has an Audio In, provided the source device has a suitable output.
Decision guide
Before you buy
The piano should be easy to share, but it also has to fit on a desk that serves other purposes. A smaller bare body and separate listening connections count for more here than a larger speaker-power number.
What this page can’t tell you
- We make no claim to a measured ranking of key action, sound quality, loudness or latency. Speaker wattage alone does not settle those questions.
- Unless stated explicitly, body-depth comparisons leave out the rest.
