Design: Minimal and tasteful, with a vintage feel

Karaoke USA is like a party packed into a compact karaoke machine. Unboxed, this machine stands a little over a foot tall and fits comfortably in any home entertainment center or coffee table. It's matte black finish, chrome-colored speaker and built-in 7” touch screen are reminiscent of classic audio equipment and made us nostalgic for our favorite classic songs.

Performance and Connectivity: Huge array of options

The Karaoke GF840 offers multiple ways to sing, record, play, and mix music. You might think,"It's 2019, who still owns CDs?"Not limited by one antique format, the Karaoke GF840 lets you pull music from a huge range of media, offering options for singing and mixing from older analog solutions or via Bluetooth from your phone or smart device. Perhaps you have your own mix on Soundcloud or a USB stick packed full of your favorite tunes—wherever your music is stored, the Karaoke GF840 has you covered.

Microphone quality is crisp and clean, offering echo and voice controls including a variety of options for mixing and recording sound.

Microphone Quality: Excellent clarity

The GF840 comes equipped with two standard microphones that plug directly into the unit, unlike other models which require you to purchase additional mics for duets. Microphone quality is crisp and clean, offering echo and voice controls including a variety of options for mixing and recording sound. 

Price: Worth the investment

The Karaoke GF840 clocks in at a retail cost of $137, and after testing this model against other options we think it's worth the price. It offers the user more options than many cheaper karaoke machines, with all the extras included in the box instead of requiring additional purchases down the line.

Karaoke GF840 vs the Singing Machine SML385BTBK

The major differences between these two machines are the bells and whistles. If a duet karaoke party is what you have in mind, the GF840 is the unit for you, due to the fact that multiple microphones are included. Both machines are relatively plug and play, but the Singing Machine SML385BTBK comes with far fewer extras (though also costs nearly half as much as the GF840, at around $70). If visual playback and DVD quality visuals are also what you had in mind for a more theatrical experience, the Karaoke GF840 is the right choice.

Karaoke GF840 is a plug and play karaoke machine that will bring you hours of entertainment. The cost of the machine aligns well with the features on offer and is ultimately a great value for the overall experience.
