Bluffante While Bose does not lace at the sonic purity (too low and linear at all) we must recognize that this small parallelepiped is extraordinary when you need background music. It is powered either by phone or by my computer and all listeners are thrilled. The power is there and we quickly forget the non-linearity of reproduction. Autonomy correct although once the red LED (battery remains 20%) are in is actually 50%. Perfect finish, minimum footprint. No unnecessary gadget.
