JBL Boombox 4. A high-power, portable Bluetooth boombox speaker with JBL Pro Sound, robust outdoor durability and long battery life — built to bring the party wherever you go.
Massive JBL Pro Sound
The Boombox 4 delivers deep, room-filling audio with powerful bass and clear highs thanks to large woofers, dedicated tweeters and multiple passive radiators — giving you punchy, dynamic sound whether you’re indoors or outside.
Adjustable bass to suit your mood
Use the Bass Boost control to switch between Deep Bass for a richer low end and Punchy Bass for a tighter, more energetic sound profile that matches your vibe.
Long battery life with Playtime Boost
Enjoy up to around 28 hours of playback on a single charge, and with Playtime Boost you can extend that up to around 34 hours — perfect for all-day parties or trips without needing to recharge.
Rugged, outdoor-ready design
Boombox 4 is built tough with an IP68 waterproof and dustproof rating, so it can handle rain, splashes, dust and outdoor conditions with ease.
Multi-speaker connectivity
Connect multiple speakers using Auracast™ wireless linking to expand stereo coverage or create a larger soundscape around your space; and pair two Boombox 4 units in stereo for wide, immersive sound.
Versatile playback & power features
Bluetooth 5.4 gives stable wireless streaming, and a USB-C port lets you connect or play lossless audio from compatible sources. You can even charge mobile devices from the speaker’s battery during outdoor use.
Portable, party-ready design
Though powerful, the Boombox 4 is lighter and more portable than previous generations, so it’s easier to carry to the beach, backyard or any gathering where big sound matters.
