Listen louder and for longer, with the JBL Xtreme 4.

Listen louder, with AI tech
When it’s time to listen loud, it’s time to bring out the JBL Xtreme 4. Packing an impressive 100 watt amp (total), two-way stereo speakers and pumping bass radiators, the JBL Xtreme 4 packs a punch. What’s more, the Xtreme 4 uses new AI Sound Boost technology for the highest volumes and lowest distortion. Analysing the signal, in real time, it pushes the drivers’ potential to their full capacity, while also reducing distortion.

Listen for longer and charge your smartphone, too
AI tech doesn’t just improve the sound quality, it helps improve battery life, too. With up to 24 hours of playback time, you’ll be able to party through the night and into the next day, too, before needing to recharge. If you need a quick boost, ten minutes of charge is all that’s needed for another two hours of music. A USB output means that you can also charge up your smartphone on the move.

Strap up for the journey
Supplied with retaining hooks and strap, the Xtreme 4 is perfectly portable and ideal for carrying on camping trips, hikes and festivals. A handy built-in bottle opener helps keep you refreshed once you’ve arrived.

Designed for extremes
Built to a robust standard, the Xtreme is designed for life on the move. Waterproof and dustproof to IP67 standards, the Xtreme 4 is more than capable of tackling muddy festival fields, sunny beaches and everything in between. Take it to a festival, a friend's BBQ or even backpacking - the JBL Xtreme 4 is built for adventure.
