JBL Boombox 4

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

Up to 34 hours of playtime

Keep the vibe alive from party to party… to party, for up to 28 hours on a single charge. Forgot to charge up for the next one? It’s all good. JBL Playtime Boost adds up to 6 hours of extra popping, locking, sliding, or whatever moves you got left in that bag

Waterproof and dustproof

The JBL Boombox 4 is IP68 waterproof and dustproof, so it can handle whatever the weather—or our clumsiest friends—throw at it
