JBL PartyBox 520 Portable Party Speaker

JBL’s Powerful Party Sound

The JBL PartyBox 520 is designed for buyers who want serious sound for parties, events and outdoor entertainment. With 400W RMS output, dual 7.5-inch woofers and dual 1-inch dome tweeters, it delivers powerful bass, clear vocals and detailed high frequencies across a wide listening area.

Whether you’re hosting a house party, outdoor celebration, corporate event, birthday or karaoke session, the PartyBox 520 is built to keep the music loud and energetic.

AI Sound Boost

JBL’s AI Sound Boost technology analyzes your music in real time and optimizes the speaker’s acoustic performance. It is designed to maximize output while reducing distortion, helping your music remain powerful and clear even when you turn up the volume.

Deep Bass with Dual 7.5-Inch Woofers

The PartyBox 520 features two 7.5-inch (208mm) woofers paired with two 1-inch dome tweeters. With a frequency response of 40Hz–20kHz, the system is designed to deliver deep bass alongside clear vocals and crisp high-frequency detail.

Futuristic JBL Lightshow

Turn your music into a complete visual experience with the PartyBox 520’s futuristic lightshow. Glowing light patterns and strobe effects react to your music, helping create an energetic atmosphere for parties and celebrations.

Up to 15 Hours of Playtime

The built-in 99.02Wh JBL BATTERY 600 provides up to 15 hours of music playback. When you need more time, the battery can be replaced with another compatible battery. A quick 10-minute charge can provide up to 2 additional hours of playtime.

Actual battery life depends on volume level, music content and other settings.

Bluetooth 5.4 & Auracast

Stream music wirelessly from your smartphone, tablet or laptop using Bluetooth 5.4. With Auracast, you can connect multiple compatible JBL speakers wirelessly, while pairing two PartyBox 520 speakers can create a true stereo experience.

Ready for Karaoke, Guitar & DJ Setups

The PartyBox 520 is more than a Bluetooth speaker. It features two XLR inputs, allowing you to connect microphones, a guitar or compatible DJ equipment. This makes it suitable for karaoke, live entertainment, parties and small events.

Easy to Move

Despite its powerful output, the PartyBox 520 is designed for portability. Its telescopic handle and wide sturdy wheels make it easier to move from your home to the car, outdoor venue, backyard or event location.

The speaker weighs approximately 25.5kg, so the wheels and handle are particularly useful when transporting it.

IPX4 Splashproof Protection

The PartyBox 520 has an IPX4 splashproof rating, making it suitable for outdoor entertainment where it may encounter light splashes.

Important: IPX4 is splashproof protection and does not mean the speaker can be submerged in water.

JBL PartyBox App

Use the JBL PartyBox App to control supported sound settings, adjust the EQ, manage music and customize the lightshow directly from your smartphone.
