The hi-fi system should be for the kids. The minimum requirements were Bluetooth and can connect an auxiliary input on the back of a PC. Already at the first pre-listening fall on the dull-sounding highs. I expect speakers of this size is no miracle, but there is already much cheaper systems have built that dome tweeter, or at least get out of a normal speaker better sounding highs. Apart from the lack of top end sound speakers as it is to be expected for the size. Furthermore, I can not understand why, although a dot matrix display is installed, but this does not display the file names when playing MP3 files. This should already be standard. Welcome to the dimensions: the system may look from the front very petite, but is about 35-40 cm in depth.
