About This Item

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.
