JBL Boombox 4 Portable BT Speaker

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 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.

Two Bass Boost settings to match our vibe
When it comes to bass, we like having options. Fire up the JBL Boombox 4 and you’ll get that classic JBL signature bass we all love. Want to take it deeper? Hitt 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 twice, the Horn mark turns white, and you’re in Punchy Bass mode. Whatever the mood, we’ve got the bass to match.

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.
