For a long time, the Yamaha U Series has been the first choice in many educational institutions, among professional musicians and expert hobby pianists.
Using a similar mechanism to the tried-and-tested Silent series, the hammers do not come into contact with the strings when desired, and digital sounds are played instead.
In contrast to Silent Pianos, however, you need neither headphones nor additional amplification: the sound is also reproduced via the soundboard if desired.
