JBL Boombox 4 Bluetooth Speaker - powerful audio performance and a long battery life. BIGGER & BETTER The new JBL Boombox 4 is bigger, bolder, and better than ever, with powerful JBL Pro Sound that stays loud and clear. We're talking massive sound with deep and punchy bass that's sure to get everybody moving! AI-ENHANCED AUDIO AI Sound Boost analyses our music in real time and adjusts the sound to deliver power with less distortion, even when you turn it all the way up! Boombox 4 packs two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. When we want to fine-tune the vibe, we just switch between deep or vibrant punchy Bass Boost settings to match our mood. BUILT FOR ON THE GO The classic Boombox design has been given an upgrade, so it's larger but lighter - perfect for taking wherever the party goes, including the beach, the back garden, or the bedroom. It's IP68 waterproof and dustproof, so weather isn't going to ruin your day. UP TO 34 HOURS BATTERY LIFE Keep the vibe alive from party to party… to party, for up to 28 hours on a single charge. Forgot to charge up for the next one? It's all good. JBL Playtime Boost adds up to 6 hours of extra popping, locking, sliding, or whatever moves you got left in that bag.
