The JBL Boombox 4 brings the boom wherever we go. It’s portable, waterproof, and dustproof—so we never stress about weather or spills. We get massive JBL Pro Sound with a Bass Boost that lets us pick between deep or punchy bass, depending on the vibe. Boombox 4 boasts bigger sound than ever before, lighter for easier carry, and up to 34 hours of playtime on a single charge.
Unbeatable JBL Pro Sound with AI Sound Boost
.We’re talking massive sound with deep and punchy bass. The redesigned JBL Boombox 4 packs in two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. And with AI Sound Boost, you don’t have to lift a finger—this smart tech analyzes the music in real time and adjusts the sound to give us more power with less distortion, even when it’s turned all the way up.
