JBL is back with a powerful upgrade to its popular portable speaker line — the Xtreme 4. Designed for those who crave bold sound and rugged durability, this speaker delivers deep bass, a long-lasting battery, and smart features ideal for both indoor and outdoor adventures. Whether you’re planning a hiking trip, hosting a backyard party, or just vibing at home, the JBL Xtreme 4 is built to be your ultimate audio companion.
JBL Xtreme 4 Overview
Immersive JBL Pro Sound with AI Boost
The Xtreme 4 packs a serious punch with its dual woofers, dual tweeters, and passive bass radiators. Its biggest innovation is the AI Sound Boost technology — a smart system that adjusts performance in real-time to deliver richer sound with minimal distortion, even at high volumes.
Extended Battery Life + Powerbank Support
Enjoy up to 24 hours of playtime, and if that’s not enough, activate Playtime Boost to squeeze out a few extra hours. Plus, the built-in power bank lets you charge your phone or other devices directly from the speaker—ideal for outdoor use.
IP67 Rated: Ready for Dust & Water
Take it to the pool, park, or trek — the Xtreme 4 is made to survive the elements. With an IP67 dustproof and waterproof certification, it can withstand sand, rain, or splashes without issue. A durable fabric and rugged housing ensure it’s ready for real-world adventures.
Bluetooth 5.3 with Auracast
Equipped with Bluetooth 5.3, the Xtreme 4 provides fast and stable wireless connectivity. It also supports Auracast, allowing multiple JBL speakers to sync together for stereo pairing or amplified group listening. However, take note that it only supports the SBC codec—you won’t find aptX or LDAC here, which may be a factor for audiophiles seeking advanced audio formats.
Easy to Carry with a Built-in Strap
Portability meets convenience with a shoulder strap that includes a built-in bottle opener—perfect for outdoor parties and picnics. The compact form and 2.1kg weight make it easy to take anywhere.
Eco-Friendly Build & Replaceable Battery
Made using recycled plastic and fabric, the Xtreme 4 reflects JBL’s commitment to sustainability. It also features a replaceable battery (sold separately), meaning your speaker can last for years with proper care and maintenance.
App Control & Sound Customization
The JBL Portable app unlocks more control over your speaker. Adjust the EQ, install updates, activate PartyBoost, and fine-tune your sound to match your vibe—all from your phone.
Sound Performance Note
The Xtreme 4 offers loud, punchy bass and crisp vocals—perfect for party environments and outdoor use. While the speaker can fill a room or open space with ease, its soundstage is more mono than true stereo, and some users might find the highs a bit sharp at maximum volume. Still, it’s one of the best portable performers in its class.
