JBL Boombox 4 - Most Powerful Portable Waterproof Speaker with Massive JBL Pro Sound

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 analyses music in real time, automatically adjusting the sound. The result? More power with less distortion, even when you turn the music all the way up.

Up to 34 hours of playtime

Keep the vibe alive from party to party… to party. This portable Bluetooth speaker delivers 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've got left in that bag.

Waterproof and dustproof

A true waterproof and dustproof outdoor party speaker with an IP68 rating. The JBL Boombox 4 is built to withstand anything— rain, sand or even our clumsiest friends.

Multi-speaker connection by Auracast™

Wouldn’t it be great to share the whole mood with the whole crew? With Auracast™, you can easily stereo pair two JBL Boombox 4 speakers for a wider sound stage or connect multiple Auracast™-enabled JBL speakers to fill every corner with the same playlist.

Two Bass Boost settings to match your 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 twice, the Horn mark turns white, and you’re in Punchy Bass mode. Whatever the mood, we’ve got the bass to match.

Bigger and louder, but lighter

The JBL Boombox 4 sounds bigger and better than ever, but here’s the real win: we redesigned it to be lighter than before. So now it’s way easier to carry this powerful handheld speaker to any party or outdoor event.

Lossless audio playback
