Main trade-off
Korg B2+
USB-C does not mean the piano is battery powered or every cable carries data.
Head-to-head
Korg B2+ vs Yamaha P-145BT: Yamaha plays phone music wirelessly, Korg centers on a wired USB-C setup
The short answer
Choose the P-145BT for wireless phone music and a shallower practice spot. Choose the B2+ when its USB-C connection and NH keyboard are a better fit for your wired setup.
Before you choose
The reasoning and the trade-offs
A shallow body leaves more room for everything behind it
P-145BT is 268 mm deep compared with 336 mm for B2+, a 68 mm saving. If the piano shares a desk with a monitor or papers, that is useful room before adding the rest and cables. The keyboard width remains roughly similar, so check the whole support surface.
What this is based on
B2+: Depth before music rest 336 mm. P-145BT: Depth before music rest 268 mm. B2+: Listed width 1312 mm. P-145BT: Listed width 1326 mm. Conditional workflow inference from these documented inputs. No matched performance measurement.
Main trade-off

About this comparison
Korg B2+ vs Yamaha P-145BT: compare keyboard mechanism, depth before music rest, computer usb connector and the practice routines that change the better choice.
These simple weighted 88-key pianos both support direct USB audio and an optional three-pedal setup. The buying boundary is a USB-C-led routine versus Bluetooth backing tracks and a shallower body.
Winner by situation
Start with what you need it to do
Desk depth is the limiting placement measurement
P-145BT is 268 mm deep compared with 336 mm for B2+, a 68 mm saving. If the piano shares a desk with a monitor or papers, that is useful room before adding the rest and cables. The keyboard width remains roughly similar, so check the whole support surface.
- Korg B2+
- Good
- Yamaha P-145BT
- Better fit
You want phone music without an audio cable
P-145BT receives Bluetooth audio and provides USB audio. B2+ documents USB-C audio and MIDI plus an analog audio input, rather than Bluetooth reception. A phone music routine is easier to plan with Yamaha, while a deliberately wired setup can work well with Korg.
- Korg B2+
- Caution
- Yamaha P-145BT
- Better fit
Your compatible computer or phone setup is built around USB-C
B2+ uses a Type-C port for MIDI and audio. The data cable, device compatibility and any phone adapter still need checking, and the piano still needs its power adapter. This matters when a beginner sees USB-C and expects a battery-powered instrument that works with any charging cable.

P-145BT is 268 mm deep compared with 336 mm for B2+, a 68 mm saving. If the piano shares a desk with a monitor or papers, that is useful room before adding the rest and cables. The keyboard width remains roughly similar, so check the whole support surface.
How we reached this conclusion
B2+: Depth before music rest 336 mm. P-145BT: Depth before music rest 268 mm. B2+: Listed width 1312 mm. P-145BT: Listed width 1326 mm. Conditional workflow inference from these documented inputs. No matched performance measurement.
Wireless backing tracks and wired recording can coexist on Yamaha
P-145BT receives Bluetooth audio and provides USB audio. B2+ documents USB-C audio and MIDI plus an analog audio input, rather than Bluetooth reception. A phone music routine is easier to plan with Yamaha, while a deliberately wired setup can work well with Korg.
How we reached this conclusion
B2+: Included Bluetooth audio reception Not established in the checked record. P-145BT: Included Bluetooth audio reception Yes. B2+: Live USB audio interface Yes. P-145BT: Live USB audio interface Yes. B2+: Computer USB connector Type C. P-145BT: Computer USB connector Not established in the checked record. Conditional workflow inference from these documented inputs. No matched performance measurement.
USB-C reduces connector mismatch, not setup responsibility
B2+ uses a Type-C port for MIDI and audio. The data cable, device compatibility and any phone adapter still need checking, and the piano still needs its power adapter. This matters when a beginner sees USB-C and expects a battery-powered instrument that works with any charging cable.

Meaningful differences
What changes the fit
| What changes | Korg B2+ | Yamaha P-145BT | Why it matters |
|---|---|---|---|
| Keyboard mechanism | NH | GHC | Try the documented mechanism before treating its name as a guarantee about feel or mechanical noise. |
| Depth before music rest | 336 mm | 268 mm | Bare depth excludes the music rest, cable route and comfortable playing clearance. |
| Computer USB connector | Type C | Not established in the checked record | Match a data-capable cable and the host device. Connector shape alone does not establish compatibility. |
| Included Bluetooth audio reception | Not established in the checked record | Yes | Audio reception carries backing music from a supported device, not sound to wireless headphones. |
| Live USB audio interface | Yes | Yes | This determines whether compatible software can receive the internal piano sound directly over USB. |
What you give up
Every choice has a cost
If you choose Korg B2+
- The matching stand and half-pedal unit are separate purchases.
If you choose Yamaha P-145BT
- Bluetooth audio receives music. It does not establish wireless headphones or Bluetooth MIDI.
Recommendation switch
The decision flips if...
Your compatible computer or phone setup is built around USB-C
Choose Korg B2+. B2+ uses a Type-C port for MIDI and audio. The data cable, device compatibility and any phone adapter still need checking, and the piano still needs its power adapter. This matters when a beginner sees USB-C and expects a battery-powered instrument that works with any charging cable.
Desk depth is the limiting placement measurement
Choose Yamaha P-145BT. P-145BT is 268 mm deep compared with 336 mm for B2+, a 68 mm saving. If the piano shares a desk with a monitor or papers, that is useful room before adding the rest and cables. The keyboard width remains roughly similar, so check the whole support surface.
You require a verified winner for mechanical key noise or personal playing comfort
Choose neither. The manufacturer records do not provide a matched test for those outcomes. Try the instruments in your intended conditions.
What matters in practice
Before you choose
What this comparison cannot tell you
- The comparison uses documented specifications and conditional setup reasoning. We have not measured key feel, mechanical noise or speaker performance side by side.
- Dimensions describe the specified body or cabinet. Leave room for the rest, cables, bench and player.
- Check the exact Amazon model, color, supplied accessories, condition and delivery date before ordering.
