Popular Speaker Comparisons
The Ultimate Ears HYPERBOOM is a large portable Bluetooth speaker with an outstanding battery life of over 23 hours. It can get louder than its more portable sibling, the Ultimate Ears EPICBOOM, without audio becoming too compressed. While you can't bring it around on a hike, its battery life is significantly longer. That said, it can't produce quite as much bass as speakers like the JBL Boombox 3, which is a better choice for fans of bass-heavy music like EDM and hip-hop.

The JBL Boombox 3 and the Ultimate Ears HYPERBOOM are similar speakers with different strengths. The Boombox 3 can produce deeper bass than the HYPERBOOM, and it offers five extra hours of battery life, lasting up to almost 30 hours in total. It's better built with an IP67 rating for dust and water resistance, certifying it to be dust-tight and immersible in up to a meter of water for 30 minutes.
