Great for Karaoke Nights and Small Parties!
Style: X3206 with One Woofer, Style: X3206 with One Woofer
We used the speaker for a recent get-together with around 30 people, and it did not disappoint. The karaoke features and mic input were a big hit, and the party lights added a fun touch. It's super easy to use, and the sound quality—especially the deep bass—is impressive for its size. One thing I really appreciated is the audio-in and audio-out options. If you have a DJ setup, it's super convenient to connect the speaker directly to your deck—no hassle at all. Bluetooth connection took a bit longer than expected to pair, but nothing too bad. Once connected, it worked smoothly the whole night. Great buy for anyone looking for a solid party speaker with versatility!

Terrible sound quality and bass
Style: X5206 with Two Woofers
Sounds cheap, didn’t come with a charger, and the bass does not vibrate at all, so I bought got a jbl 110 the next day. The jbl is a thousand times better, the bass blew me away, and the sound is very high quality. Don’t waste your time and money on it get a jbl

Turn me up turbo
Style: X3206 with One Woofer
I bought this for my performances assuming well of the brand (I’m a musician). My biggest complaint is that I wish it were louder. There have been performances where they’ve asked me to turn the volume up and surely enough it’s already at its loudest volume 🥴. The battery life is pretty good, it’s never died on me and I’ve had 4hr gigs before. The light is also a nice touch (and can turn on and off per your request of hitting a button). It makes a sound when you turn it on and off which can also be muted if you can catch it in time. Pretty easy for me to carry from place to place. Im not sure I’d recommend it to a musician but depending on what it is you need it for- it’s truly not bad. For the price it’s pretty average and until I can invest in a louder option, it gets the job done pretty okay.

Not bad
Style: X5206 with Two Woofers
A good speaker, wish it connect to my tv without an audio cord. But the sound is not bad. It’s good for the price.
