The JBL Xtreme 4 is a robust and rugged Bluetooth speaker that excels in delivering refined, high-quality sound. Building on the success of its predecessor, the Xtreme 3, this model introduces subtle yet significant improvements. It maintains the cylindrical, waterproof, and dustproof design, enhanced with recycled materials and silicone bubble feet for added stability.

The sound quality is where the Xtreme 4 truly shines. Despite its bold exterior, it produces clear, detailed audio with tight, weighty bass and crisp highs. The AI Sound Boost feature ensures distortion-free sound even at high volumes. The speaker also offers an impressive 24-hour battery life, with an option for an additional six hours through Playtime Boost. Auracast Bluetooth technology replaces the previous PartyBoost, allowing for future-proof connectivity with multiple JBL speakers.
