JBL Xtreme 4 Bluetooth speaker – 24-hour battery life – power bank function

The JBL Xtreme 4 is a powerful portable Bluetooth speaker designed for those who want punchy outdoor sound without the bulk of a massive party speaker. Key features AI Sound Boost: This technology analyzes the audio signal in real-time to optimize driver movement. The result is more powerful sound, cleaner bass, and reduced distortion, even at full volume. Replaceable Battery & Power Bank: In addition to its excellent battery life, the battery is now easily replaceable (a major plus for sustainability). You can also use it as a power bank to charge your smartphone via the USB-C port. Auracast™ Connection: This replaces the older PartyBoost system. Auracast allows you to connect an unlimited number of compatible JBL speakers to synchronize sound on a large scale. Adventure-Ready: It features rugged rubber reinforcements and comes with an adjustable carrying strap that includes a built-in bottle opener.
