JBL turn it up JBL 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 JBL music in real time and adjusts the sound to give us more power with less distortion, even when JBL 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 JBL want to fine-tune the vibe, JBL just switch between deep or vibrant punchy Bass Boost settings to match JBL mood. JBL gave the classic Boombox design a fresh upgrade-it’s larger but lighter, so JBL 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), JBL set for the long haul. With the JBL Boombox 4, JBL carry the mood and the energy, everywhere JBL go.

Unbeatable JBL Pro Sound with AI Sound Boost

JBL 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 JBL clumsiest friends-throw at it.

Multi-speaker Connection by Auracast

Two Bass Boost Settings to Match JBL Vibe

When it comes to bass, JBL like having options. Fire up the JBL Boombox 4 and you’ll get that classic JBL signature bass JBL all love. Want to take it deeper? Hit the Bass Boost button on the top panel-the JBL Horn mark glows orange, and boom, you’re in Deep Bass mode, where those two woofers and three passive radiators go all in. Want something tighter and more energetic? Tap the button once more, the Horn mark turns white, and you’re in Punchy Bass mode. Whatever the mood, JBL got the bass to match.
