why. In the case of the Tomy Hi-Kara, which they claim is the world's smallest karaoke machine (unless others have something to say about it), we will simply list off some specifications and dimensions then allow you to judge amongst yourselves, because, really, yeah. The Hi-Kara measures just 2.75 x 2.75 x 2.75-inches in a cube format with a 2.4-inch screen that displays lyrics and happy fun animations. You have to download songs onto a proprietary cartridge from the Hi-Kara website. Finally, a headset / microphone serves microphone and listening duties for up to two people. It comes in white and pink. There you have it. We'll be over here.
