Great sound. Huge bass. Easy to use. Option to connect to battery is awesome. Super light for the size. A little pricey but I'd buy it again

I was hesitant about ordering a large speaker from a brand I’ve never heard of at such a low price but It’s been great! I bought this to use at work, warehouse type building with constant noise from large fans, AC units, dehumidifiers, etc. I use it everyday and play it loud. I’ve tried several name-brand Bluetooth portable speakers for work and returned them all because they couldn’t cut through the noise. This one cuts through all the noise easily. Good battery life, good bass, clear highs and mids. After unboxing I was slightly disappointed until I realized you need to keep the eq all the way up all the time. I don’t usually push the volume knob past 50%, the sound quality is good at high levels but 50% is already so loud I haven’t needed to push it higher. I recommend this to anyone looking for something for casual every day use

It works. Only one mic comes with the speaker. Mic uses AA batteries. Hold it close to mouth or else. But I guess this is needed for nose canceling. Speaker is big! Like bigger than a barbeque. Not loud by any means and doesn't sound good at higher volume. My 1988 Hitachi was a bit more powerful and had better sound, and it could use batteries. Had no bluetooth then and no wireless mic : ) But this product for its price would be good enough for many. I will keep it.

The general function of the speaker is pretty good and the microphone works well but the tweeter has a constant AIR sound and the lcd screen is so dim that it cant be seen in daylight. This is the second one I bought and both units had the same issue, I returned the first one but missed the return window by one day for the second one so I am stuck with it.

To answer anyone's questions.... yes. It's big and portable .......yes. it does have hard loud rumbling bass... sound quality is good. Nice....it's worth the money. Equalizer is always good to have... has another 5 buttons on bottom. Great machine. U won't be. Disappointed. ((((((Update. Led is broken. Doesn't turn back on....... took to repair shop. They said. The Led display board will cost near of what the product cost. Geeez

I like the speaker, the only problem i have is when you turn it on there's a constant whistling sound. If you have the sound up with a song going you can't hear it much but between songs and when songs have quiet parts you hear it clearly.

This speaker is awesome. We love it and the karaoke wireless mic is so cool. Hooked up easy to phone and pumps the sound perfectly. We had a party in a barn and this thing was everything we needed. Great Playlist on my Amazon music account and streamed without any issues all night long
