At first we had doubts whether this cartridge is also "audible", but we thought that we would not take any big risk at this price. All the more we were surprised that the many famous songs, which are sung by children, is really nice. Well, clearly not quite meet a child even a sound, but ultimately you can see the songs sound very good and wonderful singing along. The voices are clear and understood. Our son (24 months) hears the cartridge very happy and sings already busy with!
