The F-90 features two headphone jacks. This allows two 
people to listen through headphones simultaneously, making 
it very useful for lessons and when performing piano pieces 
for four hands. Additionally, this allows you to play without 
having to worry about bothering others around you, even at 
night.

The sound from the built-in speakers stops. Sound will 
be heard only through the headphones.
