Have this but bought for my Wii console, a Wii original, so no "homebrew" or otherwise cracked console.
According to the description, these microphones are designed precisely for it.
Could not use this however. The Wii does not recognize these microphones. Latest Operating System.
Thus, for me, unfortunately, useless - and returned to sender.
Now wrap it up again and again run to the post office.
Angrily, the seller did not taste the compatibility look like?!
