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!

The two wireless microphones are a huge bonus, delivering strong, interference-free audio that makes it ideal for karaoke, teaching, public speaking, or events. Setup was super easy, and I love the multiple input options (Bluetooth, USB, TF card, Aux, and even guitar). The Bluetooth connection is fast and stable, and the portability of this unit makes it convenient to take anywhere. Battery life is impressive too—it runs for hours without losing power. This is truly a versatile PA system and karaoke machine in one. If you need a reliable, powerful, and great-sounding speaker with mics, this is the one to get.

We were really impressed by the sound quality—loud, clear, and with great bass and treble. No distortion at all, even at higher volumes. The two wireless microphones work flawlessly at the same time, which makes it perfect for presentations, group teaching, or any setting with more than one speaker. Setup was simple (the mics were already synced with the speaker), and the multiple input options (Bluetooth, USB, Aux, etc.) make it super versatile. The design feels high quality and durable, and the portability is a huge bonus—easy to carry with the handle and strap. Great battery life too. Overall, this system exceeded our expectations and has been a fantastic addition to our home and events. Highly recommend!

I bought this portable PA system mainly for teaching group fitness classes, and it’s definitely delivered on sound quality—it’s loud, clear, and the bass really carries in a big room. It connects easily through Bluetooth, and I like that it also has USB and aux options when I need them. The two wireless microphones work at the same time without interference, and it’s super helpful that I can adjust the mic and speaker volumes separately. I really appreciate the sleek design and the fact that it’s lightweight with a strap, so moving it around is no problem. The rechargeable battery lasts long enough for multiple sessions without needing a recharge mid-use. The different sound modes also let me customize how it sounds depending on the space I’m in. Overall, it’s a versatile and well-made unit that’s been perfect for both work and social events.

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.

UPDATE: I had adjusted my review to 1* because I had some difficulties with the mics, but the seller reached out and we were able to solve the problem. I appreciate their willingness to work with me. I was looking for a product that would allow me to play music and host events outside for my church. I need the ability to communicate with people occasionally during an event, apart from the main area with a full PA setup. This device seemed to fit the bill and was a better value for the money than getting an entirely different PA setup. It's also WAY easier to setup. After using the speaker outside with the mics, this seemingly small speaker blew me away! A. It can get really loud! I was playing music and definitely didn't need to have it all the way up for it to be a strong part of the background vibe. B. The mics work very well within 20 feet of the speaker. I would recommend putting a windscreen on the mic if you're outside, as it helps with picking up extra noise from the wind. C. It has bass! Not shake the earth bass, but you can hear the low ends, which I appreciate for a portable speaker. D. Connecting to my phone was straightforward. No apps to download, just connect to the bluetooth and you're good to go. It's a bonus that I can plug my guitar into this and use it as a portable amp! This speaker does everything and more, and it does it really well.
