Top notch sound!
Great speaker! It is super loud for its size and it works great.
👏🙌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.
My favorite product I've reviewed so far!
[This review was collected as part of a promotion.] This is a great speaker! The sound quality is amazing and it has so many features! I included a screenshot from the app that shows some features like one touch play which will automatically start your playlist by tapping one button even if the speaker is off. You can connect multiple speakers for more of a party atmosphere and it has a feature in which you can speak to your part guests through your speaker. It also has standby mode which helps conserve your battery and in the app you can adjust all the sound settings you can imagine to curate the sound just for you!
