The JBL Xtreme 4 in Camouflage is the speaker you carry to the party rather than the one you leave at home. Two woofers and two tweeters, backed by a pair of pumping JBL passive radiators, produce the kind of scale and bass that fills a garden or a beach. It runs for up to 24 hours, survives an IP67 dunking behind its rugged rubber bumpers, and - a first for the Xtreme line - takes a swappable battery, so the speaker outlives the cell inside it. The camo grille is the outdoor edition of the same machine.

Key features & benefits

Massive JBL Pro Sound
Two woofers and two tweeters split the work while dual side-firing passive radiators move air for the low end, so the sound stays clean and dynamic even at the top of the volume dial.

AI Sound Boost
The processor analyses the incoming signal in real time and predicts driver movement, extracting maximum loudness and bass from the amplifiers while keeping distortion in check.

Swappable battery
The battery pack is user-replaceable, so a worn cell means a new battery rather than a new speaker - and a charged spare (JBL Battery 400, sold separately) turns a day of playback into a weekend of it.

Up to 30 hours of playtime
24 hours on a charge, plus up to 6 more with Playtime Boost, which retunes the speaker for louder, crisper output when the battery is running low.

IP67 waterproof and dustproof
Fully sealed against dust and rated for submersion in fresh water, with rugged rubber bumpers on the ends so a knock in the boot of the car is not a problem.

Auracast and stereo pairing
Pair two Xtreme 4 units for true stereo, or use Auracast to link the speaker with any compatible JBL portable speakers so indoors and outdoors play the same track in sync.

Built-in power bank
The USB-C port doubles as a charge-out, so a flat phone at the end of a long day borrows power from the speaker.

Shoulder strap and recycled materials
A detachable shoulder strap makes 2.1 kg easy to carry, and the enclosure is built with recycled plastic and recycled fabric.

Connectivity & compatibility

Bluetooth 5.3 with multi-point connection, so two source devices can stay paired at once and you can switch between a laptop and a phone without re-pairing. Works with any Bluetooth phone, tablet, laptop or smart TV. Auracast connects the Xtreme 4 to other Auracast-enabled JBL portable speakers. USB-C handles charging, speed charge and power-bank output. The JBL Portable app for iOS and Android adds EQ control, Playtime Boost and firmware updates.

Care & safety

IP67 covers fresh water only - rinse and dry the speaker after any contact with sea water, chlorinated water or sand, and make sure the USB-C port is dry before charging. Keep the port cover closed while the speaker is near water. Do not charge or store the speaker in a closed car in direct sun. Use only a genuine JBL replacement battery pack; do not puncture, crush or incinerate the battery. Clean the fabric grille with a soft damp cloth and no solvents.

Who it suits

Made for people who host outdoors: desert camps, fishing trips, beach days and chalet weekends, where the camo finish hides the dust better than a plain colour does. The 2.1 kg body and shoulder strap put it a step above a pocket speaker like the Flip 7 in both output and effort - pick the Xtreme 4 when volume and battery life matter more than slipping it into a backpack pocket.
