JBL Xtreme 4 Portable Party Speaker With 24H Battery

Sling the shoulder strap over and the JBL Xtreme 4 settles at your side with real presence — at 2.1 kilograms, this is a speaker you carry, not toss in a bag. Rubber bumpers line the edges, giving it a rugged, drop-into-the-sand-and-not-worry feel that suits its role as the anchor of a bigger gathering rather than a solo commuter piece.

Real Sound, From Real Drivers

Two 70mm woofers, two 20mm tweeters, and dual JBL Bass Radiators work together to push bass deep enough that you feel it as much as hear it, while AI Sound Boost keeps things from distorting as you crank the volume for an outdoor crowd. Frequency response runs 44Hz–20kHz, and the difference between AC mode and battery mode output is noticeable — plugged in, it hits harder.

Built to Handle the Outdoors

An IP67 rating covers splashes and dust without hesitation, and the rugged build means a knock against a cooler or a stray splash from the pool doesn’t register as a concern.

Battery Life for the Long Party

Up to 24 hours of playback, stretching to 30 hours with Playtime Boost, and a 10-minute quick charge buys another two hours when the party’s still going. The 68Wh battery is also replaceable, sold separately, so the speaker doesn’t age out with a fixed cell — and the built-in powerbank keeps phones charged while the music runs.

Connectivity for Bigger Setups

Bluetooth 5.3 with Auracast lets multiple JBL speakers share the same audio, or stereo pair two Xtreme 4 units for a wider soundstage. Recycled plastic and fabric feature in the build, rounding out a heavyweight speaker that’s competitively positioned for anyone who wants high-volume sound wherever they set up.
