Great for work
I needed a speaker for our office. Our other speaker was so good my husband has dibs on it during the workday. I wanted one that was easy to use, easy to connect, had great audio (when loud), and was cute sitting on my bookshelves at work. This one is it! Haven't tested any waterproof features since I work inside, but this is a great speaker.

👏🙌Great
The Hyperboom is an absolute game-changer in the world of audio. From the moment I powered it on, I was blown away by its crystal-clear sound, rich bass, and dynamic range. Whether you’re streaming music, watching movies, or hosting a party, this speaker effortlessly elevates any audio experience.

Wonderful just wonderful
I really like this. It is a replacement for an earlier model. I would like it if I could purchase a longer charging cord.

Awesome
I like that it matches the sea charger. I had the boom three so far no complaints at all has a lot longer charging. Than expected.

Made for loud music
Sounds good but not quality. Sounds distorted when in lower levels. Okay for needing a loud speaker for outside activities. Stick to a sound system if you want quality music.

Big on sound
This little tube has a large speaker sound. It is impressive that you have a large speaker sound from a compact design. Thanks
