The JBL Xtreme 4 is a large portable Bluetooth speaker built for loud outdoor sound. It pairs two 70 mm woofers with two tweeters and passive radiators, runs up to 70 W on battery, and is IP67 waterproof and dustproof. It adds Auracast multi-speaker pairing, multipoint Bluetooth and USB-C charging, plus a replaceable battery. It is heavier and bulkier than the Charge 5 and Flip 6, so it suits people who want party-level volume rather than a pocket speaker. Owners praise the bass and rugged build; some find it heavy to carry and note the app and EQ are basic.

Reviewers rate the Xtreme 4 as one of the loudest, bassiest portable speakers in its class, with a tough waterproof build. Most criticism centers on its weight and size and on battery drain at high volume.
