So I have previously tried the DNT system Sound2move no comparison! The Sound2Move has 2 rooms further strong rushing already on the same floor or had no receipt, the system to use in another floor, in the basement or in the garden was impossible. Therefore I have also sent back immediately. Thanks to Amazon for the good service. Due to this bad experience I had concerns that another system that operates on the same radio base works much better. Nevertheless, I have to then it struggled through again with the HAMA FL-976 to try and what can I say this system is worlds better !!! The connection is made without any problems and the speakers see without hesitation the base. The speakers not only sound great, but also the range as mentioned much better. I have the station on the 2nd floor are and may take the speakers with loose in the basement or out into the garden shed for me it rushes absolutely not! Although they are larger than the Sound2Move and possibly used batteries are not charged by the connected power supply, but have to be charged in a separate charger, but I am fully satisfied on. The speaker feel qualitatively very well and also look well made from. There is no background noise when no signal is there and through the bracket (presumably the antenna) you can also wear well. The transmitter automatically switches itself off after 90 seconds if no input signal, thus no unnecessary radiation is generated. What I also find very useful to me (since I have been on only 1 speaker output), the MONO function. Without this monofunction namely 1 speakers with me otherwise remains silent. So I can this wireless speaker so far only recommend without reservation.
