Absolutely jam-packed with modern hardware and boasting just about every software feature out there, The Karaoke USA GF839 Portable System is a true all-in-one portable karaoke machine. It's honestly one of the most well-made portable karaoke solutions I've come across to date. Right out of the box, you're working with a 7 inch TFT color screen, 300 MP3G songs ready to play, multiple microphone inputs, audio inputs that are compatible with iPods and smart phones, and much, much more. If you're looking for a portable karaoke setup that covers all of your bases, this is a fantastic option!

Karaoke USA GF839 Features

I was really blown away by the sheer number of features that the Karaoke USA machine has to offer.

What it comes with

Karaoke USA did not skimp on the peripherals with this karaoke machine. When you open the box, you'll find: two wired microphones with cords that are around 8 feet long, a remote control for the karaoke unit, 300 songs pre-loaded on two discs, a 3.5mm to RCA Audio Cable, a RCA A/V to RCA A/V Cable, and an AC adapter.

The fact that they include two mics and just about every cord you could need to operate the machine is both astounding and refreshing to me. I'm used to manufacturers really being stingy with the extras – normally you have to buy the second mic, you have to buy the auxiliary hookup, and you have to buy anything else you'd need for the karaoke machine too. But with the GF839, Karaoke USA really made sure to provide you with everything you need to get some karaoke up and running as efficiently and easily as possible.

Right away, you'll notice the portable machine's built-in “7 inch TFT digital color screen.” That's a very long description – it really just means the machine has a very good screen. 7 inches is more than big enough for a portable player and allows you to read lyrics with ease. I don't have the best eyesight in the world but everything was crystal clear to me, not like many of those other low resolution or monochrome karaoke screens out there. The screen plays videos and shows images, too – you could honestly use the machine as a portable DVD player if you ever need to.

As a bonus, the karaoke machine has standard video outputs so you can hook it right up to your home TV whenever you're not traveling with it. These additional inputs/outputs add a ton of value to portable karaoke machines. You're no longer paying just for a portable setup, but also one that can integrate perfectly with a home system. Much like the Pyle-Pro PWMA930i, It's really the best of both worlds for most karaoke enthusiasts out there.


The Karaoke USA machine comes with a built-in 35 Watt Peak Digital Power Amp. To give you a rough idea of how loud it is: 35 watts is roughly 110 decibels or so, and 110 decibels is typically the volume level associated with someone yelling close to your ear, a power saw, or a car horn. It's clear to see that this karaoke unit is more than loud enough for most every occasion you could think of. It fills entire rooms with ease, and you won't be disappointed by the crystal clear, high quality sound that this portable set up puts out.

I'm not a full-blown audiophile but I do like high fidelity audio. You're never going to get absolutely spot-on, stellar audio from a built-in amplifier, but I was still extremely happy with the sound volume and quality that this little portable karaoke machine delivers.

As for songs, the Karaoke USA GF839 comes with 300 MP3-G (mp3 files with lyrics) pre-loaded on two discs for the machine. You can check out the owner's manual for a full list of the existing music. If those songs aren't your taste, don't worry – you can play music through this setup however you want to.

It has a standard disc player that can handle CDs, DVDs, and CDs with lyrics, a 3.5mm auxiliary jack hookup, a built-in USB hookup for smart devices and USB drives, an SD card slot, and features bluetooth connectivity as an option (you have to select the bluetooth version when you add it to your cart if you want this feature!). The bluetooth is a really big deal because it brings this karaoke machine into the current digital age seamlessly.

Overall, there are almost too many audio input options to pick from. You can be sure you'll never run out of songs to sing with this karaoke machine.

As a bonus, the setup does come with audio manipulation tools too. You have individual volume control settings for each microphone along with an analog echo control, balance control, and pitch (“key”) control available at your fingertips.

Last but not least, the karaoke machine lets you record your vocal performance. The recording is available via instant playback through a USB stick or SD card, and you can apply the audio manipulation options to your recordings with ease.


You can get this karaoke machine in a few different colors - black, silver, and black with LED lights. I went for the unit with the LED lights, and I'm very happy I did. The lights are basically a mini disco-ball positioned around the speaker. They really add to the atmosphere when you get into a karaoke session, and make the singing feel that much more authentic!

Karaoke USA GF839 Portability

This karaoke setup is very portable. With the awesome screen and speakers built-in, all you have to do is grab the unit, a charger, and a microphone and you can be out the door in under a minute. The whole thing weighs less than 10 pounds, and measures a mere 13 x 10 x 17.8 inches.

The Karaoke USA unit does require an AC power source to function, but you can even buy a cheap car adapter if you want to make use of the machine while driving.

The GF839 karaoke setup strikes the perfect balance between quality and portability, without sacrificing too much on either end.

Karaoke USA GF839 Durability

This will be a short section because I have absolutely zero complaints. Karaoke USA's machine is very well-constructed. There are no loose parts, and nothing feels cheap.

On a lot of these units the controls just feel plastic-y and low quality – not the case with the GF839 unit. The whole thing just feels solid, and I'm extremely confident I won't have any issues with anything breaking for years to come. The manufacturer does offer a standard one year warranty as well, which doesn't cover accidental damage.

Karaoke USA GF839 Versatility

Like I mentioned in the audio section, this karaoke machine is absolutely more versatile than most options out there. You can literally play audio from any possible source – CDs, USB drives, SD cards, your smart phone, your iPod, your MP3 player, and more. A very common complaint about many karaoke setups is about how hard it can be to add new songs to sing. Karaoke USA literally could not have made it easier with this unit.

From a use standpoint as well, you can utilize the setup like a portable DVD player, a portable speaker, or a portable karaoke machine. The individual components that went into this machine are of such a quality that it excels no matter what sort of media you're throwing at it.

Karaoke USA GF839 Conclusion

The Karaoke USA GF839 is just about everything you could ask for in a portable karaoke machine, and then some!
