The Optical small Wonderbox is not to exceed in my eyes at the moment, looks very noble, valuable and simple.
For trips you can take these speakers also determined, however, it is heavier than it looks. Here you have to weigh up whether one puts more emphasis on sound quality or mobility, but fits loosely into a pocket.
Also enjoyable is here that one mobile phone (or other USB powered devices) directly can charge the speaker.
The sound convinced me, you would not expect that of a small box a balanced sound may occur. The additional sound option that you can turn to (Crystal Clear?), It sounds again clear. Anyone who wants to can adjust equalizer by the transmitting device still all his wishes, here too, the box draws well with overrides not too fast at the ups and downs (+ bass).
Also very pleasant is the built-in NFC feature, simply hold out cell phone and within seconds the connection is established.
When operating the speakers on battery mode, singing the output power of 20 watts to 8 watts, which hardly arises.
Negative I can not tell from that speaker, every penny was worth it for me, especially if you have the cheaper boxes as comparison.
