JBL | Bluetooth speaker PartyBox 520 - Black

The JBL PartyBox 520 is a battery-powered party speaker designed for indoor or outdoor events. With its 400 W RMS output, two 7.5″ woofers and two 1″ dome tweeters, it delivers powerful JBL signature sound with deep bass and crisp highs.

The AI Sound Boost technology optimizes audio in real time to reduce distortion at high volume, ensuring a truly immersive music experience.

Built for portability, it features an ergonomic telescopic handle and large wheels that make it easy to move despite its weight (~25.5 kg). It offers up to 15 hours of battery life with the removable JBL Battery 600, and just 10 minutes of fast charging gives you around 2 hours of playback.

It’s also splash-resistant (IPX4), ideal for outdoor parties or poolside events. The robust design includes a bass-reflex enclosure with rear diffuser, delivering a powerful and natural sound.

Connectivity is comprehensive: Bluetooth 5.4 (with LE Audio and Auracast™), USB‑C (for audio playback and charging), 3.5 mm jack input, and two combo XLR/6.35 mm jack inputs for mics, guitars or mixers. You can even link multiple PartyBox units via Auracast™ or the PartyTogether feature in the JBL PartyBox app.

The built-in light show, synced to your music, adds an immersive visual experience. RGB effects are customizable via physical controls or the app.

Top-mounted physical controls include knobs for volume, bass, treble, and buttons for Bluetooth, Auracast, Bass Boost, karaoke effects and lighting. The JBL PartyBox app enables advanced EQ settings with a 7-band equalizer, reverb/harp effects, and full karaoke control.
