Finally found the perfect Karaoke
What an amazing karaoke system! This is my fourth karaoke, and it’s the first I really liked and want to keep. With 100 watts of power and dual microphones, it delivers clear treble and great sound clarity with no interference or distortion. I love that I can adjust the volume levels for both the microphones and the speaker separately. The device connects easily via Bluetooth, the battery life is impressive, and it’s perfect for karaoke nights or small events. It’s easy to use and very reliable.

Loud, Clear, and Fun for Any Event
This voice amplifier/speaker system completely exceeded my expectations. The sound quality is crisp and powerful—100W is more than enough to fill a large room or outdoor space. Both wireless microphones connect easily and work without any static or dropouts, which makes it perfect for karaoke, parties, or even public speaking.I love that it has so many options for input (Bluetooth, USB, TF card, Aux, and even guitar). We’ve used it for family karaoke nights, outdoor gatherings, and my kids’ school events—it’s super versatile. The Bluetooth connection is quick and stable, and the built-in battery lasts through hours of use.The portability is a big plus too—easy to carry, but still delivers big sound. If you’re looking for a reliable karaoke machine or PA system with excellent volume and clarity, this one is a fantastic choice!

Compact but powerful
My teenage kids enjoyed Karaoke while on vacation, so this seemed like a great idea to have our own karaoke parties at home. This voice amplifier machine is easy to use. It pairs quickly, both the wireless microphones under UHF mode as well as our Bluetooth devices under Bluetooth mode automatically. Although to be able to use both the microphones and Bluetooth together, you have to pair the microphones first and then the Bluetooth device. It has a loud and powerful sound with good treble/vocals and bass. There are also 4 different sound effects or equalizers, and an echo function/dial for a better karaoke experience. The amplifier is well made and designed, and looks pretty cool. It is a portable size and has a handle as well as a carrying over the shoulder strap that can be attached, so easy to take along anywhere.

end up using it way more than I thought
I got this speaker setup because I help out at some local events and needed something louder than yelling. It is way louder than I thought, like seriously, people will hear you even if they are way across the field. The mics work decent and the speaker itself is built pretty solid. I did not have to mess with it too much to get it going, just turned it on and paired it up.The wireless mics are cool but kind of picky. If you move too far away or turn your head too much, the sound cuts out a little. Not the worst thing ever, but it can be annoying if you are talking a lot. I mostly stayed close to the speaker and it worked just fine. It also took me a minute to figure out all the buttons because they are not labeled great.The sound is actually not bad. I played some music through it and it came out strong and clear. My nephew even used it for an impromptu karaoke session in the backyard and the neighbors probably heard every word. The battery lasted longer than I expected too, which was nice. I also liked that it has spots for USB and stuff, in case I want to plug in different things.Overall, not a fancy setup but does the job well. A couple things could be better, like the mic range and the manual could explain stuff better, but for the price, I think it is a solid buy. It feels like something you could toss in the trunk and bring to any get together or work thing. Not the kind of thing I would usually care about, but now that I have it, I end up using it way more than I thought.

Great For the Price
Great value. The sound is excellent. Easy to charge and holds a charge for a long time. However, it takes up to 5 hours for a full charge. The microphones require you to hold them very close to your mouth to get the best amplification. Still a good product for the price.

The two wireless microphones are such a nice touch, and they both connect seamlessly with zero static or interference. I love how versatile it is with all the input options like Bluetooth, USB, and Aux, and setup took me less than a minute. The battery lasts for hours, which makes it perfect for events, karaoke nights, or even outdoor gatherings. It’s also lightweight and easy to carry around, so I can take it anywhere without hassle. Overall, this system feels super high quality, reliable, and fun to use.

The voice is crisp & clear, and love the quality of this product. It is a bit heavy, mostly because of its high quality and is very well made. My kids love singing their favorite poems & songs all the time. I was able to connect my phone & tried a karoke on youtube. The phone & both the mics connected easily on bluetooth with the speaker. I would definitely arrange a karaoke night with my friends for this.
