JBL PARTYBOX 520 

Turn It Up with the JBL PartyBox 520
Make every moment a full-blown event with the JBL PartyBox 520 — the ultimate portable party speaker designed to bring bold sound, deep bass, and electrifying energy wherever you go. Equipped with JBL’s most powerful Pro Sound yet, this beast delivers a thunderous 400W RMS output powered by dual 7.5″ woofers and high-fidelity dome tweeters. What sets it apart is the next-gen AI Sound Boost technology, which dynamically optimizes your music in real time, keeping it loud, clean, and free from distortion, even at max volume.

Lights, Music, Action
Let the beat guide the vibe. The built-in futuristic lightshow syncs to your playlist with pulsing patterns and intense strobe effects, transforming any space into an immersive party zone. Whether you’re lighting up the backyard, rooftop, or basement, the JBL PartyBox 520 makes sure the energy doesn’t just come from the sound — it’s a full sensory experience.

Battery That Goes the Distance
Designed for all-day and all-night fun, the PartyBox 520 offers up to 15 hours of playtime on a single charge. Running low? Just 10 minutes of quick charging gives you another 2 hours of playback. And if that’s not enough, the replaceable battery (sold separately) lets you swap in fresh power and keep the party alive without missing a beat.

Built for Big Setups, Anywhere
With JBL Auracast™, you can wirelessly connect multiple PartyBox 520s — or other JBL Auracast-enabled speakers — for a wall of sound that scales with your event. Want a proper stereo setup? Pair two units for an immersive left-right audio experience that can fill any venue.

DJ-Level Control with Ease
Take command of the party from your phone using the JBL PartyBox app. Adjust EQ settings, trigger sound effects, control the lightshow, and manage your playlist — all without leaving the dance floor. Whether you’re streaming, DJing, or just hanging out, the app keeps you in charge effortlessly.

Made to Move
Despite its powerful output and durable build, the PartyBox 520 is designed with portability in mind. An integrated telescopic handle and rugged wheels let you roll it anywhere with ease. And thanks to its IPX4 splash-proof rating, it’s ready to rock at the beach, by the pool, or wherever things might get a little wild.

Plug In and Perform
Want to bring your own talent into the mix? The PartyBox 520 offers easy plug-and-play XLR inputs for a microphone, guitar, or DJ console. Whether it’s karaoke, live sets, or a quick speech between songs, you’ve got pro-level connectivity at your fingertips.

Built Responsibly
JBL didn’t just build this speaker to be powerful — they built it responsibly. The PartyBox 520 includes recycled plastic and fabric components and ships in FSC-certified packaging printed with sustainable soy ink. It’s big sound with a smaller footprint.
