Nice little detail: it is possible to connect several different ways. Either with the supplied USB cable (single on one side to connect it to a computer and double the other to connect to each speaker; this cable is also used for charging) or jack (each speaker has a male jack wound in it + a female jack), possibly by chaining (cable jack male / male from one computer to a cable jack and integrated speaker of the chamber to the female jack of the other).
In short: efficient, practical, well thought. And besides, not unpleasant to the eye. What more?
