The catch
Roland FP-30X
An existing wired player has nowhere to plug in, since there’s no analog audio input. A headphone socket or line output can’t take that source.
Side by side
Roland FP-30X vs Korg B2+: Korg’s analog input cannot enter USB recording, but Roland shares headphones
Quick verdict
FP-30X is the choice for two direct headphone listeners, provided shared volume is acceptable and its 3.5 mm and 6.35 mm sockets, or suitable adapters, fit your plugs. Leave Speaker Auto Mute on for quiet practice. Because it has no analog input, backing music has to come over supported USB or Bluetooth audio. B2+ is the choice for a suitable analog player, when one headphone socket is enough, matching stereo AUDIO IN and PHONES cables stay within 3 m and the source volume can be adjusted. That input cannot be sent into USB recording. Neither piano combines analog input with two direct headphone sockets unless you share equipment.
Before you buy
Why, and what it costs you
Having someone else listen doesn’t call for a second playing zone
Roland’s two sockets let a teacher hear a student’s normal playing with no splitter. Make sure the stereo plugs or adapters match the 3.5 mm and 6.35 mm sockets, expect to share one volume, and keep Speaker Auto Mute on for quiet use. Separate listening levels and two independent pedal setups are not part of the deal. A backing track still has to come over supported USB or Bluetooth audio, because Roland has no analog input.
Where this comes from
According to Roland’s manual, two people may use headphones at the same time, and speaker muting and Twin Piano pedal behavior are covered separately. Korg’s manual lists a single PHONES socket. What is being compared is hearing a normal keyboard performance together. It is not an untested routing arrangement for two players.
The catch
Korg B2+
With a single PHONES socket, only one headphone connection can listen directly. Anyone else listening needs separate sharing equipment that suits the setup.
Roland FP-30X
- Why pick it
- FP-30X suits two headphone listeners if shared volume works for both of them and their plugs, or separate stereo adapters, fit its 3.5 mm and 6.35 mm sockets. Quiet practice means leaving Speaker Auto Mute on. With no analog input, backing music has to use supported USB audio or Bluetooth audio.
- The catch
- An existing wired player has nowhere to plug in, since there’s no analog audio input. A headphone socket or line output can’t take that source.
Korg B2+
- Why pick it
- One listener with a suitable analog player can use B2+ with a matching stereo cable into its 3.5 mm AUDIO IN. One headphone socket has to be enough. Keep AUDIO IN and PHONES cables within 3 m and adjust the source volume. The analog track is audible through the piano, but you cannot record it over USB.
- The catch
- With a single PHONES socket, only one headphone connection can listen directly. Anyone else listening needs separate sharing equipment that suits the setup.

What this page compares
Roland FP-30X or Korg B2+? See how each handles two headphone listeners or an analog music player, along with the plug, cable and recording limits that change the choice.
The problems here are separate. A quiet lesson is about who can listen, and practicing along with an older music player is about where the sound comes from. Roland lets two people plug headphones in directly, while Korg can take an analog track into the piano. Begin with the people and gear already in your room so you don’t pay for a feature that sits unused.
Which one fits
Pick the situations that sound like you
The student plays as usual while a teacher listens on headphones
With Roland, two listeners can skip the splitter as long as their stereo plugs or adapters fit the 3.5 mm and 6.35 mm sockets and they are fine sharing one volume. Leave Speaker Auto Mute on when the room needs to stay quiet. A teacher doesn’t have to switch on Twin Piano just to listen in. There is no analog input, so backing tracks have to arrive over supported USB or Bluetooth audio.
- Roland FP-30X
- Better fit
- Korg B2+
- Caution
A single player plays along with a CD player they already own, using its analog audio output
When one headphone socket is enough, Korg can keep using a suitable player’s analog output, run through the right stereo cable into its 3.5 mm AUDIO IN. Both the AUDIO IN and PHONES cables should stay within 3 m, and the volume gets set at the source. You hear the track through the piano, but it does not show up in a USB recording. Plan for AC power and a supported playing position.
- Roland FP-30X
- Not suitable
- Korg B2+
- Better fit
A single listener whose source is already confirmed to work with either piano over USB audio
Given one listener, no need for an analog input and the right data cable or device adapter, neither of the main differences picks the piano for you. Confirm current device support and that the headphone plug matches. On Roland, leave Speaker Auto Mute on for quiet use. On Korg, the PHONES cable has to stay within 3 m. Judge the whole setup, and play both keyboards without presuming one wins on sound or key feel.

- Similar
- Korg B2+
- Similar
You need both an analog player and two direct headphone connections, and no sharing equipment is allowed
Out of the box, neither piano covers both needs. Roland has no analog input, and Korg has just one headphone socket. A plug-size adapter can’t add a second listener connection or turn an output into an input. Look at another piano, or rethink the rule against add-ons.

- Not suitable
- Korg B2+
- Not suitable
You already own a verified, separate way to split Korg’s headphone output
If a specific sharing setup has already been verified with both pairs of headphones, it can get around Korg’s single socket. Analog playback itself still calls for a suitable source, a matching stereo AUDIO IN cable, volume adjustment at the source, and AUDIO IN and PHONES cables that stay within 3 m. It also still can’t get into a USB recording. Look up the added gear’s own power, cable and level needs.
- Roland FP-30X
- Depends
- Korg B2+
- Depends
You also need the analog backing track recorded into a computer through the piano’s USB port
Korg states outright that AUDIO IN is left out of its USB audio output, and Roland has no analog input at all. So neither piano by itself satisfies this recording need, although both document USB audio for supported digital connections. Set up a separate recording path that suits the job, and don’t assume the headphone mix is what lands in the USB recording.

In practice
Differences you will notice
Having someone else listen doesn’t call for a second playing zone
Roland’s two sockets let a teacher hear a student’s normal playing with no splitter. Make sure the stereo plugs or adapters match the 3.5 mm and 6.35 mm sockets, expect to share one volume, and keep Speaker Auto Mute on for quiet use. Separate listening levels and two independent pedal setups are not part of the deal. A backing track still has to come over supported USB or Bluetooth audio, because Roland has no analog input.
How we worked this out
According to Roland’s manual, two people may use headphones at the same time, and speaker muting and Twin Piano pedal behavior are covered separately. Korg’s manual lists a single PHONES socket. What is being compared is hearing a normal keyboard performance together. It is not an untested routing arrangement for two players.
An old music player may flip the recommendation
With the B2+, a suitable analog CD player can stay connected through its current output. That works only if one headphone socket is enough, the matching stereo AUDIO IN and PHONES cables each stay within 3 m, and you adjust the volume at the source. The track plays through the speakers or headphones. It does not go into a USB recording. If your source is a supported digital one, this reason to favor Korg goes away.
How we worked this out
Korg’s main manual names the input connector, sends the signal to the speakers and PHONES, limits cable length, and keeps that signal out of USB output. Its product page talks about playing along with an external audio player. Nowhere in Roland’s full connector list is there an analog audio input.
Listening to the track and recording it are separate jobs
What you hear in Korg’s headphones may not be in the computer recording. Its AUDIO IN is explicitly left out of USB audio output, and Roland has no analog input. Digitizing that player takes a separate recording path that you have verified. USB audio support on both pianos doesn’t settle this analog capture job.
How we worked this out
In the B2+ main manual, AUDIO IN is expressly excluded from USB-AUDIO output. Roland documents a computer audio connection, plus a full list of physical connectors in a separate place. Neither instrument’s USB feature is taken to imply an analog capture path.
Option A
Roland, FP-30X
FP-30X
The FP-30X has two stereo headphone sockets of different sizes and supports both USB audio and Bluetooth audio. There is no analog audio input. To listen quietly with someone else, match both plugs and leave Speaker Auto Mute on.
- Best for
- FP-30X suits two headphone listeners if shared volume works for both of them and their plugs, or separate stereo adapters, fit its 3.5 mm and 6.35 mm sockets. Quiet practice means leaving Speaker Auto Mute on. With no analog input, backing music has to use supported USB audio or Bluetooth audio.
Facts we checked
- Wired headphone connections: Two stereo sockets, 3.5 mm and 6.35 mm
- Keeping the built-in speakers quiet: Headphones mute the speakers when Speaker Auto Mute is on
- Analog music coming into the piano: No analog audio-input socket
- Hearing the external analog source: Requires a different connection or external equipment
Option B
Korg, B2+
B2+
The B2+ has a stereo analog input and a single 3.5 mm headphone output. That input is heard through the speakers and headphones but is not sent to USB recording. Keep AUDIO IN and PHONES cables within 3 m, and set the source level with care.
- Best for
- One listener with a suitable analog player can use B2+ with a matching stereo cable into its 3.5 mm AUDIO IN. One headphone socket has to be enough. Keep AUDIO IN and PHONES cables within 3 m and adjust the source volume. The analog track is audible through the piano, but you cannot record it over USB.
Facts we checked
- Wired headphone connections: One stereo 3.5 mm PHONES socket
- Keeping the built-in speakers quiet: Connecting headphones mutes the speakers
- Analog music coming into the piano: Stereo 3.5 mm AUDIO IN
- Hearing the external analog source: Input reaches the piano speakers and PHONES
Spec by spec
Where they really differ
| Spec | Roland FP-30X | Korg B2+ | In practice |
|---|---|---|---|
| Wired headphone connections | Two stereo sockets, 3.5 mm and 6.35 mm | One stereo 3.5 mm PHONES socket | Two listeners at once is something Roland documents, though its sockets come in different sizes, so a plug adapter may still be needed. If two people must listen on Korg, you need a suitable, separate way to share its single output. |
| Keeping the built-in speakers quiet | Headphones mute the speakers when Speaker Auto Mute is on | Connecting headphones mutes the speakers | Muting is Roland’s default, though you can change the setting, so check it ahead of a quiet lesson. Even with the speakers muted, you still hear the keys being struck. |
| Analog music coming into the piano | No analog audio-input socket | Stereo 3.5 mm AUDIO IN | Korg can take sound straight from an audio player that has a suitable analog output. Roland’s headphone and line-output sockets only send sound out, so they can’t stand in for an input. |
| Hearing the external analog source | Requires a different connection or external equipment | Input reaches the piano speakers and PHONES | A solo player on Korg can hear the backing track in headphones together with the piano’s own sound. Plugging in those headphones mutes the speakers. Set the level of the incoming signal on the player. |
| Cable and plug planning | Match one mini and one quarter-inch stereo headphone plug | AUDIO IN and PHONES cables must each be 3 m or less | Look at the headphones and player you already have. Nothing about either standard package confirms that the audio cable, headphone adapter or splitter you need comes with it. |
| USB audio and the analog input | USB audio is supported, without an analog input to capture | USB audio is supported, but AUDIO IN is excluded from its USB output | Each piano can connect to a supported digital audio setup. That Korg lets you hear an analog track doesn’t mean you can digitize it through the piano. |
| Power and the selected package | AC adapter and DP-2 damper switch | AC adapter and damper pedal | Both are powered setups for practicing at home. The portable piano in either selection comes without its matching furniture stand. And having two headphone sockets doesn’t mean two playing areas that each have their own sustain. |
Trade-offs
What each pick costs you
With Roland FP-30X
- The two headphone sockets take different plug sizes and both follow the piano’s volume controls. With just any headphones, you can’t count on each listener getting a comfortable level of their own.
With Korg B2+
- Keep the AUDIO IN cable and the PHONES cable each within 3 m. If the external player is loud, turn it down at the source.
Change of plan
When the answer changes
Two people want to listen through wired headphones directly, and you don’t need an analog input
Go with Roland FP-30X. Roland comes out ahead once another person needs to listen, provided both accept a shared volume and their stereo plugs or adapters fit the 3.5 mm and 6.35 mm sockets. For quiet use, Speaker Auto Mute has to stay on. Because there’s no analog input, backing music must come through supported USB or Bluetooth audio.
Your current player needs an analog input, and a single direct headphone socket will do
Go with Korg B2+. Korg is the better fit for a suitable analog player, as long as one headphone socket is enough and the matching stereo AUDIO IN and PHONES cables stay within 3 m. Adjust the volume at the source. You don’t have to convert the source in order to listen, but the piano’s USB output can’t capture its analog signal.
You need an analog input and two direct headphone sockets together, with no sharing equipment
Neither model fits. Roland lacks an analog input, and Korg offers one headphone socket, so neither unit as sold meets both requirements. A sharing or mixing setup that you’ve verified separately could change the outcome. That gear has to be chosen on its own and checked against your player and headphones.
The analog input has to be captured via the piano’s USB audio output
Neither model fits. USB audio output explicitly leaves out Korg’s AUDIO IN, and Roland has no analog input. For this job you need a separate recording interface or a different way to connect the source.
Decision guide
Before you buy
Start by counting who needs headphones, then look at the output on the music player you will really use. Meeting one requirement does not take care of the other.
What this page can’t tell you
- The basis for this comparison is the exact manufacturer manuals and connection specifications. It does not rank piano tone, key action, headphone loudness, recording quality or latency from hands-on testing.
- Korg’s main manual states outright that the analog AUDIO IN is not sent through USB audio. Hearing a track in headphones is no proof that a computer recording will contain it. We do not promise any workflow that records several sources simultaneously.
- No splitter, headphone amplifier, mixer or adapter in particular has been tested here. An accessory that you verify separately can change the choice, but the number of connectors alone says nothing about its compatibility or acceptable listening levels.
