The JBL Xtreme 4 is a large portable Bluetooth speaker built for loud outdoor sound. It pairs two woofers with two tweeters for JBL Pro Sound, adds AI Sound Boost to push the drivers harder, and runs up to 24 hours on a charge, with a Playtime Boost mode adding up to 6 more. It is IP67 waterproof and dustproof, has a built-in powerbank to charge a phone, and links to other Auracast-compatible JBL speakers. It suits people who want party-level volume and bass they can carry, and it is bigger and heavier than the Charge series, so it trades portability for output.
