Review: Amazing Sound! - I bought this strictly to be a karaoke machine with friends. I expected the sound to be subpar, and only good for fun. My jaw literally dropped though the first time I played a song to test out the Bluetooth connection. I have some very high end speakers and studio monitors that I use as an editor, and this thing blew 99% of modern speakers I’ve heard, owned and used out of the water! The bass is so rich and deep and you can feel the vibrations! The highs are good too, though the mids get a bit muddled in certain types of songs. This isn’t anything most would notice, and the mids are still better than a different $400 speaker I have. The only speakers that have better mids are my studio monitors and all of my highest end over the ear headphones. It’s worth it for the bass though, and even audiophiles will be impressed! So far, the 2 mics work great straight out of the box. They make my mediocre voice sound decent, and I’m not embarrassed to belt out high notes like usual! I’ve connected it to my tv through Bluetooth to try too. The delay is quite significant, so definitely recommend the optical connection instead of Bluetooth for this reason. But it’s fine for YouTube karaoke to just use Bluetooth because the delay makes it easier to follow along with the words actually. I do hate the power button and auto power off. It seems to power off way too quickly and there’s no options to change it. Tge mics can’t turn the power on and off on the machine, so you have to manually hold the power button down for 5 secs on the top of the speaker which is annoying if you’re already situated on the couch ready to binge Netflix. But this is obviously a very minor inconvenience that only tech spoiled humans in 2022 could ever complain about. Also, The mics auto power off every 20-30 min too, even if you’re constantly pushing buttons. I have to turn the mics on 6-7 times just to get through Hamilton haha. So it’s kind of annoying and a buzz kill with friends singing ridiculously to Hamilton and then all of a sudden their mic cuts out in the best moments… Still, for the price, you are getting an amazing home karaoke system that doubles as an amazing Bluetooth speaker! 100% worth every penny!
Review: Pretty Happy with It - I bought this for a group gathering on a whim and honestly everyone loved it. The sound quality was great, 2 wireless microphones were nice for duos (though the effects didn't seem too noticeable), and hooking it up was easy (YouTube provided all the karaoke content). Lastly I don't Karaoke very often, but still found a use for it as a pretty decent sound bar for my office TV given it's form factor and look (downside being it doesn't default to the optical input for this use and ostensibly has to be set to it every time but it's marketed as a Karaoke machine so I can't really complain about that). *My unit was missing the remote control it should have came with but emailing the support address got me a remote pretty painlessly.

### ⭐⭐⭐⭐ Good box! Big bass... maybe too much
*by A***R on April 10, 2026*

Very easy to use. Sounds MUCH better than most karaoke machines. Only negative is the base is very strong and there's no equalizer.
