This is the Noxom 2 wireless audio adapter. Here is the deal, but I'm sure you smart Gizmodo readers could figure it out anyway. Connect it to your wireless network and then plug it directly into a hi-fi block-rockin' stereo system and let the polka beats roar. This little diddy (about Jack and Diane) goes for the large sum of 199.00 or $239 normal currencies.
