Strong sound very nice speaker.

David W 08-09-2020


This speaker was purchased to use outdoors at the beach and it’s amazing. Love the deep lows sounds especially the bass, incredible that it comes out of such a small speaker. Top notch sound quality. The battery life is excellent, last a very long time and we use it a lot. Connects easily thru Bluetooth. Looks very nice too. The top lights up with a soothing white light. For the value this portable Bluetooth speaker is a great purchase.

Solid buy, best price for a portable 30Watt BT speaker

Einar E 08-07-2020


After seeing my friends pick up these Bluetooth speakers for their workouts I had to get one to be cool too. This one was on sale and was the same price as the outgoing model so I had to grab this one. Sound is clear. Bass is strong. Compared to the other 30Watt speakers out there, this one was the most affordable. I kinda wish the brand wasn’t slapped on the side covering the speakers but that’s a small gripe. It’s not exactly the most marketable brand out there which is why I liked the design of their other models at lower power levels. But I wanted something that blew away the others. Bluetooth range is shorter than the other brands. I got around 5 hours of play time. It’s got a nice heft to it and feels very solid without any flex. I’ll see how it holds up over the next few months compared to the other brands but I’m fairly happy with this.
