BOOMBOX3
Transportable Waterproof Speaker with Powerbank
JBL’s most powerful portable Bluetooth speaker is now 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, with a new subwoofer added, unleashing deeper bass and richer JBL Original Pro Sound with lower distortion. While this may be a Boombox in name, its sound far exceeds what you’d remember from the boomboxes of yore, with a more balanced response, added warmth, and clean refinement.
This is a heavy duty transportable speaker. 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.
rugged rubber housing keep the speaker safe even when outdoors.
Send sound to Boombox 3 through Bluetooth or connect with a wire. Wirelessly connect up to two smartphones or tablets to the speaker and take turns sharing your favourite sounds. Or, for wired listening, plug in your audio device using the 3.5mm Aux input.
PartyBoost allows you to pair two JBL PartyBoost-compatible speakers together for stereo sound, or link multiple speakers to truly pump up your party. Use the dedicated PartyBoost button or the JBL Portable app.
Maximize your audio experience with the JBL Portable app. Get updates and product support straight from your phone. Then adjust settings and customize sound with the equalizer.
Don’t put the party on pause. A built-in powerbank lets you charge your devices without taking a break from the tunes — just plug your device’s USB-A charging cable into the Boombox 3.
JBL is committed to more sustainable, earth-friendly packaging. That’s why the Boombox 3 comes in a recyclable paper-based box, including the inner tray, with an exterior printed with soy ink.
