Our take on the Singing Machine SML682BT

The Singing Machine SML682BT Groove Mini is a compact, battery-powered karaoke console with a built-in speaker, a wired microphone and Bluetooth. It plays CD+G discs and shows lyrics on a connected TV over HDMI, and it adds six voice-changing effects plus music-synced lights. It suits kids, parties and travel, where its portability beats full-size home systems. Against pricier Singing Machine models it gives up a second microphone input, a remote and lyric display on the unit itself, so duets and disc-free lyric reading are limited.
