JBL BOOMBOX 4 Bluetooth SPEAKER - Blue, JBLBOOMBOX4BLUAS
Most powerful JBL portable waterproof speaker with massive JBL Pro Sound
Key Features:
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, 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.
Multi-speaker connection by AuracastTM
Wouldn't it be great to share the whole mood with the whole crew? With AuracastTM, effortlessly stereo pair two Boombox 4 speakers for a wider sound stage or connect multiple AuracastTM-enabled JBL speakers to cover more ground with the same playlist.
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? 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, we've got the bass to match.

Why Buy?
Massive outdoor sound that travels anywhere
Transform any location into your personal concert venue with sound so powerful it fills large outdoor spaces while staying crystal clear at maximum volume. The AI Sound Boost technology automatically adjusts each track for deeper bass and cleaner highs without the harsh distortion you get from lesser speakers.
Whether you're hosting poolside gatherings, camping trips, or beach days, this speaker delivers up to 34 hours of continuous music that won't quit when the party's just getting started. The IP68 waterproof rating means complete submersion protection, so splashes, rain, and sand won't silence your soundtrack. Two bass settings let you dial in the perfect sound for your environment — deep and rumbling for open spaces, or tight and punchy for more intimate settings.
The rugged build handles whatever you throw at it while the AuracastTM technology lets you wirelessly connect multiple speakers for room-filling sound that follows you from the deck to the garden. With its substantial battery life and weather-resistant design, you'll never have to choose between great sound and outdoor adventures again.

- You want waterproof audio for pool, beach, or boat activities
