Our Verdict
If you want a piano that fills the living room with rich sound without needing external speakers, the B2's powerful built-in audio is unmatched at this price.
Pros
- ● Powerful 30W speakers — loudest in this price range
- ● 120-note polyphony — above average for the price
- ● Very affordable entry point
- ● USB audio interface built in (USB MIDI/Audio)
- ● Includes Skoove and KORG Module software
Cons
- ● Only 12 sounds
- ● No Bluetooth
- ● No recording or lesson function
- ● No layer/split mode
- ● Single 3.5mm headphone jack
The B2 is the best value in our database. For under $400, you get speakers that sound like they belong on a much more expensive instrument and a perfectly decent weighted keyboard. It strips away the extras — no Bluetooth, no recording, no fancy modes — but what's left is a piano that sounds great in a room and won't make you feel guilty about the price.
Technical Deep Dive
About the Key Action
The keys have a solid, weighted feel — you can tell there's a real mechanism inside, not just springs. The heavier bass keys and lighter treble keys give you a sense of playing a real instrument. The touch is straightforward and honest, though players with acoustic piano experience may find it slightly less refined than pricier alternatives.
Who Is This Piano For?
You want to try piano without making a big financial commitment, and you mostly picture yourself playing in the living room with the sound filling the space. Maybe it's a gift for yourself or a grandchild, and you want something that sounds impressive right out of the box without needing to buy extra speakers or accessories.
