The size is adapted to the sound. the unit looks great and is not as platzeinnehmend like Philips AS351. She is everywhere where it is needed and can support a normal sized room enough.
The Bluetooth range conforms to the standard, so that a smartphone during playback on the smartphone belonging power supply can be charged without having to be placed in close proximity to the D80 must.
Some buyers complain about the fact that the device is not transportable therefore be equipped with batteries, which I personally find redundant, since this fact comes from the item description before you buy produce. So if anyone wish to do so, he needs to acquire, of which there are plenty to choose from in the network to another device. Whether then, however, thanks to the smaller dimensions of the sound is acceptable as the D80, I doubt.
All in all a great plus for this small but extraordinary device.
