The JBL Boombox 4 is engineered for those who demand massive sound without sacrificing portability. Designed to be the center of any party, it delivers a formidable 210W RMS output powered by two 5-inch woofers and two 1.75-inch tweeters, ensuring deep bass and crystal-clear highs whether you are indoors or at the beach. Performance is elevated by the new AI Sound Boost technology, which analyzes and adapts audio in real-time to increase volume and clarity while minimizing distortion. Users can further customize their listening experience with Dual Bass Modes, choosing between 'Deep Bass' for a cinematic feel or 'Punchy Bass' for high-energy tracks. Built for the elements, the Boombox 4 boasts an IP68 rating, making it fully waterproof, dustproof, and drop-proof. It is significantly more portable than its predecessor, weighing nearly 2 lbs lighter at 7.5 kg, making it easier to transport to pool parties or outdoor adventures. Connectivity is modernized with Bluetooth 5.4 and Auracast™ technology, allowing you to wirelessly link multiple JBL speakers for a massive surround sound experience. For audiophiles, the inclusion of a USB-C audio input enables high-resolution, lossless audio playback directly from compatible devices. Battery life is a standout feature, providing up to 34 hours of playback when using the Playtime Boost mode. With a fast-charging USB-C port and a rugged build that withstands extreme conditions, the JBL Boombox 4 represents a premium blend of durability and sonic power.
