Having Bluetooth connectivity opens up a whole world of musical possibilities. I was able to pull up karaoke tracks on YouTube and streaming apps and cast them wirelessly to the machine. The Bluetooth connection worked flawlessly up to 30+ feet away, so I could control the music right from my phone anywhere in the house. No more being tied down next to the machine!

The freedom of wireless control let me easily queue up songs on the fly based on requests from family and friends. We could keep the music and fun flowing all night without interruptions.

Versatile Audio Playback

While the Bluetooth connectivity is excellent for streaming wireless audio, the SML650BK also has options for playing music directly. This karaoke system can play tracks in MP3 and MP3+G formats, covering all the major audio file types.

I tested playing MP3s loaded onto a USB flash drive, and the playback worked perfectly. Having support for these formats is a must for playing your karaoke song library. The SML650BK also has aux-in and aux-out ports, so you can connect external devices like a smartphone or tablet if desired.

No matter how I wanted to access my music library and karaoke tracks, this machine had me covered. The versatile playback options make it easy to queue up your favorite songs for a night of karaoke fun.

Vibrant LED Display

Nothing gets you in the karaoke spirit like having visuals to follow along with the lyrics. The SML650BK has a bright, 3-digit LED display that shows song titles and track information.

As I played various audio files, I was impressed by the vibrancy of the display. The extra-large text makes it easy to view the song titles from a distance, so everyone in the room can know what’s playing.

Having the track data on display adds to the karaoke experience and helps others sing along or queue up the next song. The LED display brings a bit of that live karaoke flair right to your living room.

Voice Changing Effects

One of the most entertaining parts of karaoke is getting playful with vocal effects. The SML650BK comes equipped with six built-in voice changing effects: Echo, Bass, Treble, Robot, Falsetto, and Reverb.

My friends and I had a blast taking turns testing out the different effects and belting out our favorite tunes with voice modulation. The echo effect was perfect for dramatic ballads, while robot or bass gave a fresh twist to classic pop songs.

I was very impressed by the volume the compact system could produce. The stereo separation gives a panoramic soundscape that fills the whole room. Vocals and mid-range tones come through clearly to help guide your singing. Even at max volume, there was minimal distortion.

The dynamic audio performance will have you belting out tunes with energy and enthusiasm. The speakers bring concert-like sound that gets everyone engaged and eager to join the singalong.
