The small Rokono Speaker is very well made and leaves a very sophisticated look. The sound is clear, even if the highs are partially penetrant. Bass can not be expected in such a Mini-Speaker. The volume is more than adequate. But when Notebook Speaker on the go, he is quite well suited for example, to amplify the sound from laptop or smart phone and do something more balanced. Only a slight background noise in operation in the quiet location and low volume, I find disturbing. But this is barely noticeable during normal operation. In addition, you would also have the system sounds but can make more cautious. The voice output on power up and connect are extremely annoying. The Bluetooth connection is fast and the range is einwandrei.
