Customer Ratings & Reviews

The sound quality is outstanding, with deep, powerful bass and crystal-clear highs, even at high volume. The battery lasts a long time, the light show adds a fun atmosphere, and it’s easy to move around thanks to the built-in wheels and handle. Whether it’s for backyard parties, family gatherings, or just enjoying music at home, this speaker delivers every time. Definitely worth the investment. I highly recommend it to anyone looking for loud, high-quality sound in a portable package.

The quality of the product is incredible, it is portable for any site, it sounds amazing and it is easy to control, I would always recommend it.

This speaker is amazing, the bass is off the charts, sound is so clena

The bass is very powerful and the sound is very clear especially at higher volumes. The light show this new JBL speaker displays is fantastic for any backyard or indoor party. The switchable battery life is also a perk to have in case you need more hours of music playing. You can also use this device to plug in your guitar which is a plus. The app is user friendly and it has many cool settings to make your experience of the speaker better.

High quality best sound best battery lifetime Really good product

Considered a Stage 520 but decided it was too big for my need. I have a Stage 320 but got tired of hauling it downstairs to to pool cabana each time I wanted to use it. The Stage 330 get pulled out on my upstairs screened in porch and paired with my Stage 320 and Charge 6. The range of Auracast is very impressive. My entire home is immersed in great music. Love it.

The lights add a nice flair and definitely amplifies the room, the battery life doesn’t feel like a true “16hours” playing above 50% volume and lights going. But worth every penny a lot of people knock it for some controls being removed but they’re just in the app.

This speaker is unbelievable. Crisp clear sound with nice deep bass. Can’t wait to get a second one for thee ultimate sound. Highly recommended!!!

If you want a box woth thump this is the one... i love thump wven on my car so i needed a speaker that gave me the same feeling and i love it...
