JBL Xtreme 4 Portable Bluetooth Speaker – Waterproof Wireless Speaker

The JBL Xtreme 4 Portable Bluetooth Speaker (Black) is a rugged, high-performance audio companion designed to bring thunderous JBL Pro Sound wherever your music takes you. Its powerful speaker setup — including dual woofers and tweeters — produces rich bass and detailed highs that fill outdoor spaces and large rooms with immersive sound, making it ideal for parties, gatherings, and everyday listening.

With up to 24 hours of continuous playtime on a single charge, the Xtreme 4 can keep the soundtrack going from sunrise to sunset, and its Playtime Boost feature can extend playback by several extra hours when needed. The IP67 waterproof and dustproof rating means the speaker is built to handle splashes, dust, and rain — perfect for poolside afternoons, beach trips, backyard barbecues, and other outdoor adventures without worry.

Wireless Bluetooth 5.3 streaming lets you quickly connect your smartphone, tablet, or other compatible devices for seamless music playback, while Auracast™ and multi-speaker connectivity make it easy to pair the Xtreme 4 with other JBL speakers to expand sound even further. AI Sound Boost technology enhances audio output by optimizing the speaker’s performance in real time, reducing distortion and maximizing loudness for a clean, powerful listening experience.

Practical extras like a built-in powerbank let you charge your phone or accessories on the go, and the included shoulder strap makes it easier to carry this robust speaker from place to place. Compact yet rugged and feature-packed, the JBL Xtreme 4 is a versatile choice for anyone who wants bold, portable sound with durable design and long battery life.
