Not that bad ... but everything else as well

Notable confounders: The fixed, much too short AUX cable that is virtually useless. On most tablets can not use it makes sense and therefore still need an extra extension cord. For movies and games but does so without AUX no sense, since Bluetooth creates a delay, so that the picture and sound are asynchronously. The Bluetooth range is not exactly brilliant, outdoors there from 6m distance already connection problems.

The annoying voice that every time gives me status messages through, that bothered me even when other speakers. Simple audio signals are there in my opinion meaningful. Especially since the voice is quite loud.

In his main discipline of Mobi 2 is not really usable. Because unfortunately it is tuned very high tones. Of course you can from a mini speaker expect any bass orgies, but it is for the manufacturer, the Speaker at least halfway neutral vote, which is not the case here. A very unpleasant tweeter Peak tarnishes the listening quite formidable. Really pleasant to hear is the little screamer not in any case, I would recommend to take rather a few euros more into their own hands. For a very unobtrusive background music it is to use, after all, if the size plays a very important role, but not for more.

For everything else, you should buy at least a speaker with built-in bass membrane (passive radiator), something fits loosely in a backpack and take at least a usable sound.

I forgive even 2 stars, as many in this tiny size (eg Rokono Bass, X-Mi Mini 2, Aiptek air2U) sound very much worse.
