JBL Boombox 4 - Pro Sound, 34h Playtime, IP68 Waterproof, Auracast

Powerful, portable, and ready for any setting

The JBL Boombox 4 reimagines what a portable speaker can do. Bigger sound, smarter tuning, and tougher build, all wrapped in a lighter, easier-to-handle chassis that travels from sunlit beaches to dim backyard evenings.

At the heart of the Boombox 4 is JBL Pro Sound with AI Sound Boost. Real-time analysis helps the system deliver more power with less distortion as you push the volume, while two larger woofers, two tweeters, and three passive radiators give each track weight, clarity, and reach. When the mood shifts, you can toggle between Deep Bass and Punchy Bass to tailor the low end to your scene.

What you get in everyday use

• Performance and tuning: AI Sound Boost analyzes music in real time for cleaner output at high volume; two bigger woofers, two tweeters, and three passive radiators reproduce broad, confident sound.
• Bass options: Deep Bass adds a rumble for cinematic vibes; Punchy Bass delivers tighter, more energetic lows for upbeat playlists.

Designed for life on the move, the Boombox 4 blends bigger sound with portable convenience. It’s IP68 waterproof and dustproof, so weather, sand, and spills don’t have to stop the party. The chassis is larger for an immersive presence, yet lighter to carry, so you can take the energy wherever you go.

• Long playtime and flexible power: Up to 34 hours on a single charge, with Playtime Boost extending the fun when you need it.
• Durability and sustainability: recycled plastics and fabric, FSC-certified packaging, and a replaceable battery option for longer-term use.

Connectivity and versatility extend the Boombox 4’s reach. Auracast enables easy stereo pairing or multi-speaker setups, so the same playlist can fill larger spaces without a separate mixer. A USB-C port supports lossless audio from compatible devices for those who value onboard fidelity. A replaceable battery adds another layer of flexibility, and the overall design prioritizes practical, real-world use—whether you’re hosting a summer gathering or a weekend get-together with friends.
