JBL Xtreme 4

The JBL Xtreme 4 is a powerful portable Bluetooth speaker designed for loud, bass-rich sound with two woofers, two tweeters, and dual passive radiators, plus AI Sound Boost for clearer audio at high volumes. It offers up to around 24 hours of battery life (with a boost mode to extend playback), is IP67-rated for waterproof and dustproof protection, and includes a built-in shoulder strap for easier carrying. It also works as a power bank to charge devices and supports Auracast for linking multiple compatible speakers, making it a rugged, outdoor-focused speaker built for parties, travel, and all-day listening.
