Features and technical details

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.

P68 Waterproof and Dustproof: Highly resistant to dust and water for worry-free outdoor use in any weather.`

Multi-speaker Auracast™ connectivity: Can pair two Boombox 4 speakers for wide stereo sound, or connect multiple Auracast™-enabled JBL speakers for a bigger party experience.

Dual Bass Boost modes: Instantly choose between “Deep Bass” for immersive lows or “Punchy Bass” for energetic, tight bass with an LED-lit JBL logo indicating the current mode.

Larger, louder, but lighter: Improved portable design with more output power, yet lighter than previous models for easier transport.
