Ready to provide your next outdoor adventure with massive JBL Pro Sound, the Xtreme 4 Portable Wireless Waterproof Speaker from JBL in blue, features dual 2.8″ woofers, dual 0.7″ tweeters, and dual passive radiators. Your music will sound balanced and have benefit of rich, deep bass response; even at high volumes thanks to AI Sound Boost. Experience the great outdoors without worry as you stream your favorite music via Bluetooth. The Xtreme 4 is waterproof, dustproof, and has rugged rubber bumpers to handle bumps and impacts. The huge, replaceable battery can play your music for up to 24 hours, with an extra 6 hours available via a tap of Playtime Boost.
AI Sound Boost
Using AI Sound Boost, the Xtreme 4 can maximize its already impressive sonic capabilities. AI Sound Boost analyzes the incoming audio signal in real-time, while simultaneously using an AI algorithm to predict the loudspeaker movement and power response. The result is the ability to push the drivers to their maximum capability, fully exploiting dynamic range, maximizing volume and bass, while minimizing distortion.
Use Battery as Power Bank
If your phone or tablet is running low on power, you can use the massive 9444 mAh LiPo battery as a power bank to recharge your device. Simply plug it into the Xtreme 4 via the USB-C port.
Pair for Bigger Sound
If the large soundstage of the Xtreme 4’s JBL Pro Sound is somehow not enough, you have the option of pairing it to a second Xtreme 4 speaker for bigger, stereo sound. You can also wirelessly connect the Xtreme 4 to other PartyBoost or Auracast-enabled speakers in order to share music across a wide array of available speakers.
JBL Portable
The JBL Portable app lets you update the Xtreme 4’s firmware, unlock new features, access product support, and the built-in EQ. Make custom EQ adjustments or select from one of the EQ presets.
Eco-Friendly
With an eye on sustainability, JBL partially constructed the Xtreme 4 from recycled materials, and packaged it in FSC-certified paper that’s printed with soy ink.
