My wife had to learn the piano needs. Then I dealt with the issue a bit and came across this variation of a piano or piano. Meanwhile, my wife has rehearsed a few things and together we are excited about the Yamaha NP-31. For "normal" -Practice the built-in speakers are enough certainly, but develop properly be doing "very good" sound only from the headphones or on my 5.1 system - even long-time pianist stood there already surprised in our living room. Conclusion: Optimal for learning, without much technology-frills and very space-saving. With the headset or on the "good" system, the sound is absolutely perfect ... just Yamaha!
