JBL Boombox 4 Portable Bluetooth Speaker, Waterproof, Deep Bass - Black | Up To 34 Hours Playtime, IP68 Dustproof, AI Sound Boost For Louder Clearer Audio, Ideal For Beach, Pool, Boat And Outdoor Par

We turn it up our way—anywhere. The all-new JBL Boombox 4 is bigger, bolder, and built to hit harder, with massive JBL Pro Sound that stays loud and clear no matter how far you crank it. Two bigger woofers, two tweeters, and three passive radiators work together to make every track feel like an event. And AI Sound Boost is quietly doing the heavy lifting in the background—analyzing your music in real time, adjusting the sound to keep things powerful and distortion-free, even at full volume. When it comes to bass, you've got options. Hit the Bass Boost button and drop into Deep Bass mode for that low, earth-moving rumble. Tap it again and Punchy Bass kicks in—tighter, more energetic, ready to match a different kind of mood. Up to 34 hours of playtime means you're covered from the backyard cookout well into the night, and if you need a little extra, JBL Playtime Boost adds up to 6 more hours when you need it most. Built for wherever the vibe takes you—beach, boat, block party—the IP68 waterproof and dustproof rating means weather is never a dealbreaker. We redesigned it to be lighter than before too, so it's actually easy to bring along. Pair two Boombox 4 speakers via Auracast for stereo sound, or connect additional Auracast-enabled JBL speakers to spread the playlist further. With the JBL Boombox 4, we carry the mood and the energy, everywhere we go.
