JBL Boombox 4 Portable Bluetooth Speaker

The JBL Boombox 4 delivers massive JBL Pro Sound in a portable, rugged design built for all-day listening. With two woofers, two drivers and three passive radiators, it aims to fill spaces with deep bass, clear details and robust output. AI Sound Boost analyses music in real time to optimise balance and minimise distortion, ensuring powerful, clean audio across volumes. The speaker is IP68 rated, making it waterproof and dustproof for adventures near water, sand or dust. A built‑in power bank lets you charge devices without pausing playback, and the battery is replaceable so you can swap in a new one as needed. JBL One app provides sound controls and pairing features for easy setup.

Designed for versatility, the Boombox 4 supports lossless audio for faithful playback and pairing with Auracast-enabled speakers for a wider soundstage. You can connect additional Boombox 4 units for bigger audio coverage, or link multiple speakers to share music, choosing Deep Bass or Punchy Bass modes to suit the mood. The device includes upgraded Bluetooth 5.4 for reliable multi‑device connectivity, a lighter yet larger chassis, and USB‑C compatibility for enhanced sound when paired with compatible lossless sources.

Extra notes for clarity: the speaker is designed to handle adventurous use with a durable build, realistic battery compatibility and straightforward app-based controls. It is engineered to remain audible and balanced across different environments, from beach outings to backyard parties, with a focus on bold, immersive sound.
