I find this great collection, and my daughter 16 months which has almost all the volumes do not get tired. It is with a big smile she welcomed this new book (Volume 1 is really good) until it activates the chip .... and starts yelling, pushing the book, as if she was afraid. And indeed the sound is too loud! We can not even take pleasure in listening to music since the volume is just too aggressive. I do not know what happened at gallimard youth (it's the same as another new seemed "exotic birds") because there is no worry of this kind on precedent. I found that just for once, the sound was well balanced! And since the design of the book it is impossible to "tape" to reduce the volume a bit, as on certain other collections. It's a real disappointment and I so recommend. Too bad!
