First: The sound is very good for such a small device. What's bugging me, however, that the connection to the wireless network is very difficult. The device recognizes only a few networks and precisely mine was not there, although a Repaeter in was the same room. It was only when I came even closer to the device to the Repaeter, the network has been detected. I was the Hama Internet-Radio IR250 unconvinced.
