Price-performance is really very good at EasyAcc® Music Cube. I am still surprised at what and especially also that comes a volume from the speaker for a sound. It reaches all the time from outside to enjoy music with a few people. Especially if you put the box on a table or at best in a way box or the like, a unglaubich bodied sound comes with an extreme bass from the small thing. Thus, this box all other devices to 30 clearly in the shadows. The stamina is equally remarkable. Until now I have it out of the box not even charged and I hear since significantly more than 15 hours. Thus, the manufacturer's specification is very realistic. I could now make no real negative points up. Only the quality of the microphone is rather average, but this is also not the Haubtaufgabe this otherwise excellent box.
