Good sound, antenna with great range, although if you throw a party and play music when someone passes between the transmitter and receiver there are interruptions. It is practically difficult to connect with Samsung s10, while all BT devices connect immediately, this one requires drivers and there is no application in the Play store... and no instructions to search for (Many calls were made to the store and the representative). With 50 euros more, you can get the WiiM pro plus streamer which has BT (Award-winning product)
