The JBL Boombox 4 delivers massive sound with deep, punchy bass. Packed with two bigger woofers, two tweeters, and three passive radiators, every track hits harder and sounds cleaner. AI Sound Boost analyzes your music in real time and adjusts the sound for more power with less distortion – even at max volume.

Up to 34 hours of playtime (28 hours + 6 hours with Playtime Boost) keeps the vibe alive from party to party. IP68 waterproof and dustproof – it handles whatever the weather or your clumsiest friends throw at it.

Auracast multi-speaker connection lets you stereo pair two Boombox 4 speakers for a wider soundstage, or connect multiple Auracast-enabled JBL speakers to cover more ground with the same playlist.

Two Bass Boost settings – classic JBL signature bass, Deep Bass mode (orange glow) for deeper bass, or Punchy Bass mode (white glow) for tighter, more energetic bass.

Lossless audio playback via USB-C port – plug into your laptop or audio device for lossless audio (source must support lossless audio). The replaceable battery (sold separately) extends the life of your speaker.

Redesigned to be bigger and louder, but lighter than before – easier to set the tone wherever you go. Incorporates post-consumer recycled plastic and recycled fabric, packaged in FSC-certified paper printed with soy ink.
