Our take on the Singing Machine Bluetooth Karaoke Machine with LED Lights (SML640)

The Singing Machine SML640 is a compact home karaoke system with a built-in speaker, LED light show, one wired microphone and Bluetooth streaming from phones and the Singing Machine app. It also plays CD+Graphics discs, shows lyrics on a TV over RCA, records performances to a USB drive and has two mic inputs for duets. It suits families and casual singers who want a self-contained party box without a separate sound system. Against app-only party speakers it adds disc playback and vocal recording; against bigger systems it gives up HDMI, DVD and a rechargeable battery.

Questions and answers

Does it work without a TV?
Yes. The built-in speaker plays music and the mic works on its own. A TV is only needed to show CD+Graphics lyrics.

Yes, there are two wired mic jacks. Only one microphone is included, so you need a second wired mic for duets.
Can I record my singing?
Yes. Performances can be recorded to a USB drive plugged into the machine.
Does it stream from a phone?
Yes, it pairs over Bluetooth with phones and tablets, and it also works with the Singing Machine app for karaoke tracks.
Does it play DVDs?
No. It plays CDs and CD+Graphics discs only, plus Bluetooth and USB audio.
Is it battery powered?
No, it runs on mains power, so it stays near an outlet.
