Main trade-off
Roland FP-30X
There is no analog audio input for an existing wired player. A headphone socket or line output cannot accept that source.
Head-to-head
Roland FP-30X vs Korg B2+: Roland shares headphones, Korg’s analog input cannot enter USB recording
The short answer
Choose FP-30X for two direct headphone listeners when shared volume and its 3.5 mm and 6.35 mm sockets or suitable adapters work. Keep Speaker Auto Mute on for quiet practice. It lacks analog input, so backing music needs supported USB or Bluetooth audio. Choose B2+ for a suitable analog player when one headphone socket suffices, matching stereo AUDIO IN and PHONES cables stay within 3 m and source volume is adjustable. That input cannot enter USB recording. Neither combines analog input with two direct headphone sockets without sharing equipment.
Before you choose
The reasoning and the trade-offs
A second listener does not need a second playing zone
A teacher can hear a student’s normal performance without a splitter through Roland’s two sockets. Match the 3.5 mm and 6.35 mm stereo plugs or adapters, accept shared volume and keep Speaker Auto Mute on for quiet use. This does not create separate listening levels or two independent pedal setups. Any backing track still needs supported USB or Bluetooth audio, since Roland lacks analog input.
What this is based on
Roland’s manual explicitly permits two people to use headphones at once. It describes speaker muting and Twin Piano pedal behavior separately. Korg’s manual identifies one PHONES socket. This comparison concerns hearing a normal keyboard performance together, not an untested two-player routing arrangement.
Main trade-off
Korg B2+
One PHONES socket limits direct listening to one headphone connection. A second listener requires separately suitable sharing equipment.
Roland FP-30X
- Choose it for
- Two headphone listeners favor FP-30X if shared volume suits both and their plugs or separate stereo adapters fit its 3.5 mm and 6.35 mm sockets. Keep Speaker Auto Mute on for quiet practice. It has no analog input, so backing music must use supported USB audio or Bluetooth audio.
- Main trade-off
- There is no analog audio input for an existing wired player. A headphone socket or line output cannot accept that source.
Korg B2+
- Choose it for
- One listener with a suitable analog player can use B2+ through a matching stereo cable to its 3.5 mm AUDIO IN. One headphone socket must suffice. Keep AUDIO IN and PHONES cables within 3 m and adjust source volume. You can hear the analog track through the piano, but cannot record it over USB.
- Main trade-off
- One PHONES socket limits direct listening to one headphone connection. A second listener requires separately suitable sharing equipment.
About this comparison
Compare Roland FP-30X and Korg B2+ for two headphone listeners or an analog music player, with plug, cable and recording limits that change the choice.
A quiet lesson has a listening problem. Practicing to an older music player has a source problem. Roland can connect two headphone listeners directly. Korg can bring an analog track into the piano. Start with the people and equipment already in your room rather than buying a feature you will not use.
Winner by situation
Start with what you need it to do
A teacher listens on headphones while the student plays normally
Roland removes the splitter requirement for two listeners whose stereo plugs or adapters fit 3.5 mm and 6.35 mm and who accept shared volume. Keep Speaker Auto Mute on for quiet use. The teacher need not use Twin Piano just to listen. Backing tracks require supported USB or Bluetooth audio, since there is no analog input.
- Roland FP-30X
- Better fit
- Korg B2+
- Caution
One player practices to an existing CD player with an analog audio output
Korg can retain a suitable player’s analog output through the correct stereo cable to its 3.5 mm AUDIO IN, when one headphone socket suffices. Keep both AUDIO IN and PHONES cables within 3 m and adjust source volume. The track is audible through the piano but absent from USB recording. Provide AC power and a supported playing position.
- Roland FP-30X
- Not suitable
- Korg B2+
- Better fit
One listener uses a source already confirmed to work with either piano over USB audio
With one listener, no analog-input requirement and the correct data cable or device adapter, neither main difference chooses the piano. Check current device support and the matching headphone plug. Keep Roland Speaker Auto Mute on for quiet use. Keep Korg’s PHONES cable within 3 m. Compare the complete setup and try both keyboards without assuming a sound or key-feel winner.

- Similar
An analog player and two direct headphone connections are both mandatory, with no sharing equipment
Neither base piano supplies both features. Roland lacks the analog input. Korg has only one headphone socket. A plug-size adapter does not add a second listener connection or turn an output into an input. Choose another piano or reconsider the no-add-ons requirement.
- Roland FP-30X
- Not suitable
- Korg B2+
- Not suitable
You already have a separately verified way to share Korg’s headphone output
An exact sharing setup already verified with both headphones can remove Korg’s single-socket obstacle. Analog playback still requires a suitable source, matching stereo AUDIO IN cable, source-level adjustment and AUDIO IN and PHONES cables within 3 m. It still cannot enter USB recording. Check the added equipment’s own power, cable and level requirements.
- Roland FP-30X
- Depends
- Korg B2+
- Depends
The analog backing track must also be recorded into a computer through the piano’s USB port
Korg explicitly excludes AUDIO IN from USB audio output. Roland has no analog input. Neither piano alone meets this recording requirement, even though both document USB audio for supported digital connections. Use a separately suitable recording path rather than assuming the headphone mix is the USB recording.

What matters in practice
The differences that matter
A second listener does not need a second playing zone
A teacher can hear a student’s normal performance without a splitter through Roland’s two sockets. Match the 3.5 mm and 6.35 mm stereo plugs or adapters, accept shared volume and keep Speaker Auto Mute on for quiet use. This does not create separate listening levels or two independent pedal setups. Any backing track still needs supported USB or Bluetooth audio, since Roland lacks analog input.
How we reached this conclusion
Roland’s manual explicitly permits two people to use headphones at once. It describes speaker muting and Twin Piano pedal behavior separately. Korg’s manual identifies one PHONES socket. This comparison concerns hearing a normal keyboard performance together, not an untested two-player routing arrangement.
The old music player can reverse the recommendation
A suitable analog CD player can keep its existing output connection with B2+. One headphone socket must be enough, the matching stereo AUDIO IN and PHONES cables must each stay within 3 m, and source volume needs adjustment. The track reaches speakers or headphones but not USB recording. A supported digital source removes this particular reason to prefer Korg.
How we reached this conclusion
Korg’s main manual names the input connector, routes the signal to speakers and PHONES, restricts cable length and excludes that signal from USB output. Its product page describes playing along with an external audio player. Roland’s full connector list has no analog audio input.
Hearing the track and recording it are different jobs
The backing track heard through Korg’s headphones is not necessarily in the computer recording. AUDIO IN is explicitly excluded from USB audio output, and Roland has no analog input. Digitizing that player therefore requires a separate verified recording path. Both pianos supporting USB audio does not resolve this analog capture job.
How we reached this conclusion
The B2+ main manual expressly excludes AUDIO IN from USB-AUDIO output. Roland documents a computer audio connection and a separate complete physical connector list. No analog capture path is inferred from either instrument’s USB feature.
Choice A
Roland, FP-30X
FP-30X
FP-30X has two differently sized stereo headphone sockets and supports USB audio and Bluetooth audio. It has no analog audio input. For a quiet shared listen, match both plugs and keep Speaker Auto Mute on.
- Best matched use
- Two headphone listeners favor FP-30X if shared volume suits both and their plugs or separate stereo adapters fit its 3.5 mm and 6.35 mm sockets. Keep Speaker Auto Mute on for quiet practice. It has no analog input, so backing music must use supported USB audio or Bluetooth audio.
Checked facts
- 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
Choice B
Korg, B2+
B2+
B2+ has a stereo analog input and one 3.5 mm headphone output. Its input reaches the speakers and headphones, but not USB recording. Keep AUDIO IN and PHONES cables within 3 m and set the source level carefully.
- Best matched use
- One listener with a suitable analog player can use B2+ through a matching stereo cable to its 3.5 mm AUDIO IN. One headphone socket must suffice. Keep AUDIO IN and PHONES cables within 3 m and adjust source volume. You can hear the analog track through the piano, but cannot record it over USB.
Checked facts
- 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
Meaningful differences
What changes the fit
| What changes | Roland FP-30X | Korg B2+ | Why it matters |
|---|---|---|---|
| Wired headphone connections | Two stereo sockets, 3.5 mm and 6.35 mm | One stereo 3.5 mm PHONES socket | Roland documents two simultaneous listeners. Its differently sized sockets may still require a plug adapter. Korg needs a separately suitable way to share its single output if two people must listen. |
| Keeping the built-in speakers quiet | Headphones mute the speakers when Speaker Auto Mute is on | Connecting headphones mutes the speakers | Roland defaults to muting, but the setting can be changed. Check it before a quiet lesson. Muting speakers does not remove the physical sound of playing the keys. |
| Analog music coming into the piano | No analog audio-input socket | Stereo 3.5 mm AUDIO IN | An audio player with a suitable analog output can feed Korg directly. Roland’s headphone and line-output sockets send sound out and cannot substitute for an input. |
| Hearing the external analog source | Requires a different connection or external equipment | Input reaches the piano speakers and PHONES | Korg can let a solo player hear the backing track through headphones along with normal piano playing. Connecting those headphones mutes its speakers. Set the incoming level at 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 | Check the headphones and player you already own. Neither selected standard package establishes that your required audio cable, headphone adapter or splitter is included. |
| 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 | Both can connect to a supported digital audio setup. Korg’s ability to let you hear an analog track is not a way to digitize that track through the piano. |
| Power and the selected package | AC adapter and DP-2 damper switch | AC adapter and damper pedal | These are powered home-practice setups. Neither selected portable piano includes its matching furniture stand. Two headphone sockets do not establish two separately sustained playing areas. |
What you give up
Every choice has a cost
If you choose Roland FP-30X
- Two headphone sockets use different plug sizes and share the piano’s volume controls. Independently comfortable levels are not guaranteed with arbitrary headphones.
If you choose Korg B2+
- AUDIO IN and PHONES cables must each stay within 3 m. A loud external player requires adjustment at the source.
Recommendation switch
The decision flips if...
Two people need direct wired headphone listening and no analog input is required
Choose Roland FP-30X. Adding a second listener favors Roland when both accept shared volume and their stereo plugs or adapters fit its 3.5 mm and 6.35 mm sockets. Speaker Auto Mute must remain on for quiet use. With no analog input, any backing music needs supported USB or Bluetooth audio.
The existing player needs an analog input and one direct headphone socket is enough
Choose Korg B2+. A suitable analog player favors Korg when one headphone socket suffices and matching stereo AUDIO IN and PHONES cables stay within 3 m. Adjust source volume. This avoids converting the source for listening, but cannot capture its analog signal through the piano’s USB output.
Both analog input and two direct headphone sockets must be present without sharing equipment
Choose neither. Roland has no analog input and Korg has one headphone socket. Neither base unit meets both requirements. A separately verified sharing or mixing setup could change the decision, but that equipment must be chosen separately and checked with your player and headphones.
The analog input must be captured through the piano’s USB audio output
Choose neither. Korg’s AUDIO IN is explicitly excluded from USB audio output. Roland has no analog input. A separate recording interface or different source connection is needed for that job.
What matters in practice
Before you choose
Count the people who need headphones, then check the output on the music player you will actually use. One requirement does not solve the other.
What this comparison cannot tell you
- This comparison uses 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 explicitly says its analog AUDIO IN is not sent through USB audio. Hearing a track in headphones does not prove that a computer recording will contain it. No simultaneous multi-source recording workflow is promised.
- No particular splitter, headphone amplifier, mixer or adapter has been tested here. A separately verified accessory can change the choice, but connector count alone does not establish its compatibility or acceptable listening levels.
