Experience the most powerful battery-powered PartyBox yet with JBL PartyBox 520, and host your next karaoke party with JBL PartyBox Encore 2

London, 13 March 2025 – Take the party anywhere as JBL drops two new PartyBox speakers. Powerful sound, immersive light shows, and seamless multi-speaker connectivity. Featuring

JBL Pro Sound and proprietary technology AI Sound Boost, these speakers optimise audio output for dynamic bass and crystal-clear treble, ensuring the music sounds flawless, whether in the living room or poolside in the backyard. With key features like replaceable batteries, Auracast™ for limitless speaker pairing, and durable splashproof designs, JBL continues to deliver the ultimate audio experience for any occasion.

“JBL has solidified its position as the number one portable and party speaker brand by consistently delivering unmatched sound and innovation,” said Carsten Olesen, President, Consumer Audio at HARMAN. “These new PartyBoxes build on that legacy, offering the advanced technology and durability that have made JBL the go-to choice for audio experiences worldwide. Whether at a large event or a small gathering, JBL continues to define what it means to bring people together through sound.”

Bigger, bolder, and louder. JBL PartyBox 520 is the newest speaker in the PartyBox lineup, and the most powerful battery-powered speaker in the series. Built for large gatherings, the speaker’s IPX4 splashproof design and rugged telescopic handle, combined with wider, sturdier wheels, make it easy to take the party anywhere.  JBL PartyBox 520 offers up to 15 hours of playtime on a single charge, and with replaceable batteries and fast-charging capabilities, the music can keep going without interruptions. AI Sound Boost analyses the music signal in real time to optimise and push the driver to its maximum capability, ultimately creating a more powerful, less distorted sound. Plus, Auracast™ allows easy pairing with other Auracast™-enabled JBL speakers, creating a fully connected sound system to fill every corner of the venue.
