About
JBL Boombox 4 Portable Bluetooth Speaker
Bring bigger sound to every party with the JBL Boombox 4, a powerful portable Bluetooth speaker built for bold, room-filling audio indoors and out. Designed with upgraded woofers, tweeters, and passive radiators, it delivers deep bass, crisp highs, and the kind of full-scale sound that makes music feel alive. JBL’s AI Sound Boost helps optimize audio in real time, so your playlists stay powerful and clear even when the volume is pushed higher.
Made for long days and late nights, the Boombox 4 offers up to 28 hours of playtime on a single charge, with Playtime Boost adding up to 6 more hours for a total of up to 34 hours. Whether you’re heading to the backyard, beach, pool, or campsite, its IP68 waterproof and dustproof design is ready for the elements. A redesigned build makes it bigger and louder while still easier to carry, giving you high-output performance without sacrificing portability.
For even more immersive sound, the Boombox 4 supports Auracast™, letting you stereo-pair two speakers or connect multiple compatible JBL speakers for wider coverage. You can also switch between two Bass Boost modes to match the energy of the moment, from deeper low-end rumble to a tighter, punchier profile. And for listeners who want more detail, the USB-C connection supports lossless audio playback when used with compatible source content and services.
