JBL Xtreme 4 – Powerful Portable Bluetooth Speaker

The JBL Xtreme 4 is a portable Bluetooth speaker built for outdoor adventures, beach days, pool parties, camping trips and gatherings at home. It delivers massive JBL Pro Sound enhanced by AI Sound Boost, with up to 24 hours of playtime and an IP67 waterproof and dustproof design. A shoulder strap makes it easy to take anywhere. It also has a built-in power bank, Auracast multi-speaker connection and a user-replaceable battery.

Next-Level JBL Pro Sound

The Xtreme 4 uses two 70 mm woofers, two 20 mm tweeters and dual pumping JBL bass radiators to deliver dynamic, immersive sound with deep bass. When plugged into power, output reaches 2 × 30W RMS (woofers) plus 2 × 20W RMS (tweeters). On battery, output is 2 × 20W RMS plus 2 × 15W RMS. Frequency response extends from 44 Hz to 20 kHz, with a signal-to-noise ratio above 80 dB.

AI Sound Boost

AI Sound Boost analyzes the music signal in real time and adjusts how the drivers perform. This reduces distortion even at high volume and maximizes bass output, so the speaker sounds full and clear whether you're listening quietly or turning it all the way up.

Up to 24 Hours of Playtime, Plus Playtime Boost

The Xtreme 4 plays for up to 24 hours on a single charge. Tap Playtime Boost to extend battery life by up to 6 more hours. Running low? A 10-minute fast charge gives up to 2 hours of playback, and a full charge takes about 3.5 hours.

Replaceable Battery

The Xtreme 4's battery is user-replaceable, which helps extend the life of the speaker. Replacement batteries are sold separately.

IP67 Waterproof and Dustproof

With an IP67 rating, the Xtreme 4 is protected against water and dust. It's built to handle poolside splashes, sand at the beach and dusty outdoor trips.

Built-In Power Bank

The USB-C port lets the Xtreme 4 work as a power bank, so you can charge your phone or other devices while the music keeps playing.
