Now the really big disadvantage - it's outrageously loud. I have put away more than that I like to give it to the little ones the keyboard unfortunately. :(
One can nix to rumstellen and also dampen the speaker has not so hingehauen as desired. The "noise" permeates from every opening of this keyboard. ;)
Those who do not have a soundproof room and wants to use earplugs while, which I personally would advise against it and to pay attention to a volume control when general when buying a cheap keyboards advise.
The 3 stars are for the quality and the sound in general.
