👏🙌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
