Unfortunately not compatible with all Wii Sing It Games

We bought these mics for the older Guitar Hero, which you also work great. They are good in the hand and the voice reproduction is fine. Then came the more recent "We Sing German Hits" and promptly went to nothing. The software of the Wii is up to date and HUB switch etc also not brought the desired results - that's why they go back unfortunately.
Conclusion: great microphones for older Wii games, but Sing It newer versions exist on the unfortunately inferior and it is twice as expensive Logitech versions.
