(For the sake of fairness given 4 stars because I do not want to maul the unit, but please read the review!) Have returned again after extensive testing of this device. While it makes a perfectly good impression in the process, but the sound is unfortunately for me not nearly satisfactory. Since even had my little "Soundman" dice more bass! I thought that was amazing. Oddly enough, I've read before my order of the speaker in other reviews that the sound of this unit could keep up with the more expensive of much. This statement is completely incomprehensible to me. It clearly lacks the bass. A direct comparison with a Bose SoundLink Mini (costs a 158 euros) clearly shows that the savings really not worth here. Whoever did not immediately hear that there are worlds between the sound images are ... Because let's face it: We want to hear yes certainly good sounding music with these speakers. Ordered on the basis of other fairly good reviews of this device, but am sonically really been disappointed. So who wants to have good sound should definitely listen to Bose SoundLink Mini! The sounds of the bass and the space as a medium sized hi-fi speaker, and I have found comparable in size anything.
