Our take on the Singing Machine SMC273

The Singing Machine SMC273 is a compact karaoke machine with a built-in speaker, a wired microphone and Bluetooth streaming from a phone or tablet. It adds echo and light effects, records video or sound, and has a second microphone input for duets. It is a simple starter system for casual singers at home; serious karaoke fans will want a machine with a lyric display and better sound.

What reviewers say

  • 3.9 / 528 ratings

Owner feedback is limited, but the SMC273 is generally seen as an easy, affordable first karaoke machine for kids and casual use. Buyers note the small speaker and the lack of on-screen lyrics as the main limits.

  • MicrophonesMixedThe included wired microphone works, but a second one must be bought for duets.
