JBL Xtreme 4 Portable Waterproof Speaker Overview
The JBL Xtreme 4 is a rugged, high-performance portable Bluetooth speaker released in August 2024, built for outdoor enthusiasts, partygoers, and music lovers who demand booming sound without sacrificing portability. It upgrades the Xtreme 3 with enhanced bass via dual passive radiators, AI Sound Boost for distortion-free volume, and Auracast support for seamless multi-speaker syncing. Weighing 2.1kg with a built-in shoulder strap (featuring a bottle opener), it’s designed for Kenyan adventures like beach parties in Mombasa or hikes in the Aberdares—IP67-rated to withstand dust storms, rain, or submersion. The replaceable battery and powerbank function keep the vibes going all day, making it a step up from compact options like the JBL Flip series.
This speaker shines in delivering “next-level JBL Pro Sound” with balanced highs, mids, and deep bass, even at max volume. It’s eco-friendly too, using recycled plastics and fabrics. Recent X buzz from Kenyan and global users highlights its value during sales, with one post noting a slashed price ahead of Amazon’s Big Deal Days.
