JBL PartyBox 520 400W Portable Party Speaker

Bring the party anywhere with the JBL PartyBox 520. Delivering 400W of powerful JBL Pro Sound and an immersive light show, this portable speaker is designed to turn any location into a full-on event. With a rugged, splash-resistant build and swappable battery, the PartyBox 520 is ready for backyard BBQs, beach days, and everything in between.

Powerful JBL Pro Sound with AI Boost

Dual 7.5″ woofers and 1″ tweeters push out up to 400W of room-filling sound. Activate JBL’s AI Sound Boost to analyze your music in real time—automatically enhancing dynamics while minimizing distortion. Whether you’re playing bass-heavy EDM or vocal-centric acoustic sets, your tracks stay crisp and clear at any volume.

15 Hours of Battery Life & Quick Swap Power

Keep the music going with up to 15 hours of playtime on a single charge. Need more time? Swap in a fresh JBL BATTERY 600 (sold separately) or connect to AC power. A quick 10-minute charge gives you up to 2 extra hours—perfect when you’re short on time but big on vibes.

Light Up the Night

A full ring of multi-colored LEDs surrounds the dual woofers, creating a dynamic light show that syncs with your music. Choose from several customizable patterns and strobe effects to energize the atmosphere and keep the dance floor alive.

Multi-Source Playback & Live Performance Ready

Play music your way:

Bluetooth for wireless streaming
USB input for flash drives
3.5mm AUX for wired components
Dual XLR inputs to plug in microphones, guitars, or DJ consoles

Perfect for house parties, karaoke nights, and open mic events.

Expand Your Sound

Need more coverage? Link a second PartyBox 520 for stereo sound, or sync multiple JBL Auracast-enabled speakers to create a wireless speaker network for larger events.

Rugged, Sustainable, and Ready for the Outdoors

The IPX4 splash-resistant design makes it safe to use poolside or at the beach. The speaker is constructed from recycled plastic and packaged in FSC-certified paper printed with soy ink—because great sound shouldn’t come at the planet’s expense.

Built-In USB-C Charging

Charge your smartphone or tablet while the music plays. The rear USB-C port delivers up to 30W of power, keeping your devices powered through the night.
