Incredible sound for the price

Photo client de Marcus T.

I took advantage of the sale and couldn't believe the price. The first time I turned it up, the bass literally made the windows vibrate. It sounds like a system three times its size. No regrets.

This thing is POWERFUL

Photo client de Danielle R.

I threw a backyard party and never needed to go past half volume. It filled the entire yard with clear, deep sound. A neighbor even came over to ask what speaker it was.

Bass you can feel in your chest

Photo client de Greg P.

The bass is unreal. Hip-hop and EDM hit hard and stay precise even at max volume. Easily the best portable speaker I've ever owned.

Lasts all day at the lake

Photo client de Stephen K.

It played from noon to midnight at the lake house without ever dying. I'm taking off one star only because it's heavy to carry — but the sound and battery life are worth it.

Best speaker deal I've ever gotten

Photo client de Priya N.

I've wanted a Boombox forever but couldn't justify the full price. I saw the sale and jumped on it. Massive sound, all-day battery, and it survived a rainy camping trip.

Took it to the beach — IP67 is no joke

Photo client de Carlos M.

It got splashed, sat in the sand, and even took a wave. I wiped it off and it kept playing like nothing happened. Exactly what I needed for beach days.
