100W Powerful Voice Amplifier with 2 Wireless Microphones, Big Pro Sound Portable Speaker with Microphone, Bluetooth Speaker PA System Karaoke Machine Support BT/USB/TF Card/Aux/Guitar S99

We bought this for karaoke in this household and it works really well! It’s a powerful machine and can get real loud. The sound quality is very crisp. It is quite heavy, but portable. The charge lasts long and charges fast enough. No issues with Bluetooth connectivity.

I am blown away by the power of this S99 system. I needed something that could handle a large space, and this 100W speaker delivers crystal-clear "big pro sound" without any distortion. The two wireless mics sync instantly and have a great range, which is perfect for karaoke or hosting events. I also love that it has a guitar input and supports Bluetooth, it’s basically a complete PA system that I can carry with one hand. Highly recommend!

This 100W voice amplifier is surprisingly loud and clear for the size. The BT connection paired quickly with my phone and stayed stable the whole time. Great for teaching, events, or outdoor use since the sound carries really well without getting too distorted. Battery life has been solid too.

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.

For this kind of money I expected something that would work well. From the beginning and not matter the settings, the mics never operated well and had minor but sometimes crucial missteps. I one doe not one hold the mics in perfect perpendicularity and the proper distance, not to close but not too far, they would cut out. Now I have to find a good system having wasted $200. I am updating this originally one star evaluation to four stars due to the splendid response from the company. They issued a complete refund for the equipment.

This amplifier and microphone package is a really solid all-in-one setup if you need clear, loud sound without dealing with complicated gear. The 100W output gives plenty of volume for rooms, events, or outdoor gatherings, and having two wireless microphones makes it super convenient for presentations, services, or karaoke. It’s easy to connect music through Bluetooth or other inputs, and the rechargeable design makes it simple to take anywhere. The sound is strong and clear, the controls are straightforward, and the whole system feels practical and reliable — a great choice when you want powerful audio in a portable package.

This could almost have been a 5-star review, but I'm deducting two points for two different reasons. Firstly, overall I was quite impressed with it, the sound is powerful and very clear. Almost too clear at times...but there are no bass/treble controls to make any adjustments. I couldn't really hear much difference between the different mic modes, either. The major issue I had was having was the mics cutting out quite often. After a second or two they'd work again (no reset or re-pairing required). I was testing the unit in a room crammed with electronics & probably a lot of electrical interference, so I'll cut it some slack. The people actually using the unit, outdoors, didn't complain about any mic issues. One star removed for this, however. Second star lost for the misleading claim of "360 degree stereo sound". That's just a lie. The unit is 100% mono, and only delivers audio from the front of the unit. One bass driver, one tweeter, one channel of audio. The unit does mix-down stereo music files to mono, at least. That's very typical of budget Chinese products to make such inaccurate claims, perhaps someone will see this review though and update the photo with the stereo claim. Overall, pretty good, and decent value for money. I currently have no intention of returning it.

The sound quality is clear, loud, and well balanced, making it suitable for a wide range of uses such as public speaking, teaching, outdoor events, and karaoke. The 100W output provides strong volume without noticeable distortion, even at higher levels. Bluetooth pairing is quick and stable, and the speaker works well with smartphones and other devices. The build quality feels solid and durable, while the portable design makes it easy to transport. Battery performance is also commendable, lasting long enough for events and extended sessions. Overall, this is a versatile and powerful PA system that delivers professional-level performance at a reasonable price. I would highly recommend it to anyone in need of a portable speaker system for presentations, performances, or entertainment purposes.

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.

This is a super cool peice of equipment. All you gotta do is charge it and you're ready to rock. For musicians this is awesome, i am a professional musician and this comes in really handy. User friendly, easy to understand and awesome to use. I recommend this hignly.

Loving the quality on this speaker and mic! Crispy clean and it is surprisingly loud.

Amazing for singing too

Great. I teach 29 students helps a lot.
