Good quality, good price, unfortunately they do not work at Sing it!

At the microphones, there are se ncihts suspend. I had bought it for my Xbox360, but unfortunately overlooked that they are not in "Sing it!" function (Why not ??)
Otherwise, I could connect easily and for a few fun nights they are of good use. Who wants to take his own songs, but should rather rely on a decent microphone. However, for SingStar and co are a cheaper alternative!
