Boombox 4 Waterproof Portable Bluetooth Speaker Blue

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.

• Unbeatable JBL Pro Sound with AI Sound Boost - We’re talking massive sound with deep and punchy bass.

• 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
