JBL BOOMBOX 4 Portable Bluetooth Speaker, Black

UNBEATABLE JBL PRO SOUND WITH AI SOUND ENHANCEMENT

We're talking about powerful sound with deep, punchy bass. The redesigned JBL Boombox 4 features two larger woofers, two tweeters, and three passive radiators, so every song sounds louder and clearer.
With AI Sound Boost, you don't even have to lift a finger—this smart technology analyzes your music in real time and adjusts the sound to deliver more power with less distortion, even when the volume is turned up to the max.

UP TO 34 HOURS OF PLAYBACK

Keep the party going from one event to the next—and then to the next—with up to 28 hours of playtime on a single charge. Forgot to charge it for the next event? No worries. JBL Playtime Boost adds up to 6 hours of extra beat, movement, or whatever else you have in store.

WATERPROOF AND DUSTPROOF

JBL Boombox 4 is waterproof and dustproof to IP68 standards, so it can handle anything – no matter the weather or our clumsiest friends.

Connect multiple speakers with Auracast™
Wouldn't it be great to share the vibe with the whole crowd?
With Auracast™, you can easily connect two Boombox 4 speakers in stereo mode for a wider sound experience, or connect multiple JBL speakers with Auracast™ enabled to cover even more space with the same playlist.

Two bass boost settings – for every mood
When it comes to bass, we like to have options.
Turn on the JBL Boombox 4 and enjoy that classic JBL sound we all love.
Want even deeper bass? Press the Bass Boost button on the top panel – the JBL logo will light up orange and you'll be in Deep Bass mode, where two woofers and three passive radiators show their power.
For a tighter, more energetic sound, press the button again – the logo will turn white and you'll switch to Punchy Bass mode.
Whatever your mood, we have the bass to match.

Bigger, louder, and lighter
The JBL Boombox 4 sounds bigger and better than ever before—but the real win is that we've made it lighter than before.
Now it's much easier to create the right atmosphere anywhere.
