We just made our most powerful portable Bluetooth speaker even better. The iconic silhouette of the JBL Boombox 3 has a bold new update featuring a sturdy metal handle with silicone grips, twin sidecaps, and waterproof and dustproof signature fabric. It’s been redesigned inside too, added with a new subwoofer unleashing much deeper bass and massive JBL Original Pro Sound, all with lower distortion. And 24 hours of play time takes you all the way from your morning workout to a late-night hang with your friends. And for sound that’s practically limitless, instantly connect multiple speakers with the JBL Portable app.
