The decor was not a problem by means of WPS.
Whether playing with the Fritz box and the media player of Fritz Phone, iPhone, Android and using Windows Media Player directly to the speaker, there are no problems thanks to DLNA and UPNP.
The APP on Android can be improved and is not the best. Here I use in addition to controlling the audio files is an alternative (BubbleUPNP) -
A previous speaker reported problems with devices like iPhone etc - that works for me without problems - but only with a UPnP app and not via AirPlay
However, my favorite is the control by Fritz and related Fritz Phones - So you get the smartphone free.
The white LEDs are very bright, which disturbs some. The workmanship is not perfect, but for the price I see here get over it.
Personally for me are the speakers for my application (bathroom and bedroom) is sufficient.
