I just got this system. The Bose design is very good, and the order. The device is smaller than olus sce we think of after images, but very cool. I find ca despite the sound is not optimal. In any case, if it is to replace a real grater, this is not the right choice. This is normal because it does not compare to a big chain with two Speakers and settlement of bass and treble. That said, I find that Bose could have added these regulations because there is not much relief in the sound. This is especially the medium that emerge, making the sound a bit 'douf' like something out of a box. But despite ca, in general the sound is pure enough, just not comparable to a real grater. Rather for a kitchen or bedroom. In the living room I prefer my JVC listen chain of 20 who has a great sound. I the sober if I'll return this product or not. It's a handy gadget to move from one room to another can be so much in the long run. Is experienced despite the quality of Bose what is important.
