Hyperboom 2

Reviewers say it delivers deep, powerful bass with rich, concert-like sound in a sturdy build. It's built for stationary party use with long battery life and works all day without needing a charge.

It has dual Bluetooth, a 3.5mm aux input, optical input, and USB charge-out to power other devices. The app lets you set EQ presets, pair multiple UE speakers for a bigger sound, and create playlist shortcuts.

It's for buyers who want a bass-heavy party speaker that stays in one place and can run on battery for a full day. It works best for people with wired audio sources or multiple devices to connect.

Anyone wanting a lightweight speaker to carry around easily should look elsewhere. It's also not the choice if you prioritize the clearest, most detailed high-end sound over maximum bass—reviewers note some rivals sound louder and clearer.

It's large and heavy compared to most portable Bluetooth speakers. It also uses an older charging port style rather than the newer standard on other UE models.

Reviewers are split. One found a competing boombox-style speaker louder and clearer, while another ranked the Hyperboom among the very best sounding speakers tested. Opinions also differ on whether the bass-heavy tuning beats out smoother, more balanced competitors.
