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.

We turn it up our way—anywhere. The all-new JBL Boombox 4 is bigger, bolder, and better than ever, with powerful JBL Pro Sound that stays loud and clear, with deep thumping bass. AI Sound Boost analyzes our 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. It packs two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. When we want to fine-tune the vibe, we just switch between deep or vibrant punchy Bass Boost settings to match our mood. We gave the classic Boombox design a fresh upgrade—it’s larger but lighter, so we can take it wherever the party goes: the beach, the block, or the backyard. It’s IP68 waterproof and dustproof, so weather’s never a dealbreaker. And, with up to 34 hours of playtime (thanks, Playtime Boost), we’re set for the long haul. With the JBL Boombox 4, we carry the mood and the energy, everywhere we go.
