The VocoPro DVX - 668K is a great way to pump up your next party. The DVX - 668K offers Multi-format disc player reads CD, CD+G, DVD, MP3, And DivX. The usb port is great if you want to use mp3's. The VocoPro also has a great option which allows you to hook up to your stereo for 5.1 Channel Surround Sound RCA. Hope you enjoyed my review of the VocoPro DVX - 668K multi format karaoke player.
