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, we don’t have to lift a finger—this smart tech analyzes music in real time and adjusts the sound to give us more power with less distortion, even when we turn it 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.
Bigger and louder, but lighter
The JBL Boombox 4 sounds bigger and better than ever—but here’s the real win: we redesigned it to be lighter than before. So now it’s way easier to set the tone wherever we go.
