Also, it's confirmed that the PDP Headset won't work with old Wii Speak compatible games such as Animal Crossing City Folk and The Conduit. And Wii Speak won't work with PDP Headset compatible games. But both the PDP Headset and the Wii Speak must be plugged into the Wii console in order for them to work. And the wire for the PDP Headset is much shorter then the wire for the Wii Speak.
So Overall who's better? The PDP Headset or the Wii Speak? It's up to you guys in your own opinions to choose which one is better.
