As such, a good home theater system. Unfortunately, the device has hung up with me within two weeks three times, so that the plug had to be pulled. The sound is good but, for watching movies. To listen to music, it is sufficient even replaced but of course no hi-fi system. For larger volumes, the highs are reproduced little unclean. Spotify works as a premium version, not in the free version. The subwoofer must be runtergeregelt for my taste, a bit too dominant in comparison to the front speakers in the factory setting. Has played with no problems with me all formats. Provides for watching movies adequate "theater sound".
