Karaoke JoySound Wii allows Japanese Wii owners to bring the karaoke experience home, with a full music subscription service. The only problem with bringing that experience home is that Japanese apartments tend to be tiny and thin-walled.
Japan Trust Technology has solved that issue for late-night crooners with the Mute Mic USB. This specially-designed microphone includes a plastic cup that fits over players' mouths, muting the atonal, drunken screeches that would normally issue forth throughout the apartment building. As an added "bonus," it looks unidentifiably disgusting both in use and on its own, like some kind of medical device you wouldn't want to have to explain.
