JBL PartyBox 720 vs PartyBox 520: Which party speaker should you buy?

The JBL PartyBox 720 and JBL PartyBox 520 are two of the most capable battery-powered party speakers JBL makes. Both deliver big sound, customizable lighting, and flexible input options, but they differ in size, power, and portability. So which PartyBox is right for you? Let’s dive into this JBL PartyBox 720 vs PartyBox 520 comparison and find out.

What’s it like to use the JBL PartyBox 720 compared to the JBL PartyBox 520?

Aside from differences in size and output, the JBL PartyBox 720 and PartyBox 520 share the same core PartyBox design language. Both use rugged plastic enclosures with front-facing LED lighting, rear input panels, and an identical top-mounted control layout. They’re also IPX4 rated, so light rain or splashes around the pool aren’t a concern. Each speaker includes wheels and an integrated handle, making them practical to move despite their bulk.

The PartyBox 720 is the larger and more powerful of the two, delivering up to 800W of output. At around 68lbs, it’s undeniably heavy, but the wide wheels and sturdy handle make it manageable to roll across flat surfaces. The PartyBox 520 delivers 400W of power and weighs roughly 56lbs, which makes it slightly easier to maneuver on your own, especially when loading it into a car.

Visually, the 720 stands out thanks to its full-panel light show. It adds extra lighting strips flanking the grille, along with extended lighting along the top and bottom of the enclosure. The 520’s lighting is still bright and dynamic, but the 720’s additional LEDs make it noticeably more eye-catching.

How do you control the JBL PartyBox 720 and JBL PartyBox 520?

Both the JBL PartyBox 720 and PartyBox 520 use the exact same top-mounted control layout. You get physical buttons for power, Bluetooth, Auracast, and Bass Boost, along with dual dials to manage playback volume and lighting effects. Lighting controls are built directly into the top panel, so you can change effects without pulling out your phone.

There are also dedicated DJ effect buttons and microphone controls for fine-tuning vocals or instruments plugged into the rear inputs. In my testing, everything was easy to access and clearly labeled, and once the music was going, I rarely needed to open the JBL PartyBox app—though it’s still useful for deeper sound and lighting customization.

Does the JBL PartyBox 720 or JBL PartyBox 520 have more features?

The JBL PartyBox app offers plenty of control and customization for both the PartyBox 720 and PartyBox 520. From the app, you can adjust the sound using a 7-band EQ, customize the light show, tweak microphone settings, and reassign DJ effects. You can also link multiple PartyBox speakers together for synchronized mono playback, which is ideal for covering larger spaces.

If you’re after true stereo sound, you’ll need to pair two identical models. Both the PartyBox 720 and PartyBox 520 include “Deep” and “Punchy” bass modes in the app, letting you tailor the low end to your room or music style. In my testing, the app was responsive and easy to use, and once everything was set up, I rarely needed to open it again—though it’s nice to have when dialing in sound or lighting for a specific space.

How do the JBL PartyBox 720 and JBL PartyBox 520 connect?

The JBL PartyBox 720 and PartyBox 520 share the exact same wired and wireless connectivity options. Both use Bluetooth 5.4 with support for SBC and AAC codecs, along with Auracast for linking with other compatible JBL speakers. You also get a 3.5mm aux input, dual XLR–1/4-inch combo jacks for microphones or instruments, and a USB-C port that supports digital audio playback, including lossless formats.

Connection stability is solid across the board, whether streaming over Bluetooth or using wired inputs. It’s also nice to see both speakers support audio over USB-C, which makes higher-quality playback from a laptop or compatible mobile device easy without relying on Bluetooth.

Is battery life better on the JBL PartyBox 720 or the JBL PartyBox 520?

Both the JBL PartyBox 720 and PartyBox 520 are rated for up to 15 hours of battery life, though actual runtime depends on volume, lighting effects, and the content you’re playing.

The main difference comes down to battery design rather than longevity. The PartyBox 520 uses a single removable battery, while the PartyBox 720 relies on a higher-capacity dual-battery setup. In practice, both speakers can easily last through a full day or evening of use, but if you want maximum output and the strongest bass response, running either speaker on AC power is the better option. JBL doesn’t specify how power output differs between battery and plugged-in use, but both speakers still deliver plenty of volume when running wirelessly.

Does the JBL PartyBox 720 sound better than the JBL PartyBox 520?

Both speakers deliver excellent, party-ready sound that gets guests out of their chairs and onto the dance floor, but the PartyBox 720 clearly has the advantage when it comes to loudness and low-frequency performance.

Its 800W output and dual 9-inch woofers produce powerful bass strength that holds up even at high volumes. In Deep mode, bass depth feels physical indoors—closer to a club-style presentation—while vocals remain intelligible and instruments retain their clarity. Switching to Punchy mode shifts the emphasis toward the low-midrange, giving snare drums and percussion more presence. However, in my experience, most listeners prefer the fuller low-end weight of Deep mode.

The PartyBox 520’s 400W system still delivers plenty of volume for small to medium-sized gatherings, including outdoor use. Bass strength remains energetic, and the speaker maintains good clarity through the midrange and treble without sounding distorted at higher levels. For house parties or backyard get-togethers, the 520 offers more than enough output. But if you’re trying to fill a larger space or want more headroom and bass impact, the PartyBox 720’s added power makes a noticeable difference.

Should you get the JBL PartyBox 720 or the JBL PartyBox 520?

Buy the JBL PartyBox 720 if you want JBL’s loudest battery-powered party speaker with a full-panel light show, deeper bass, and flexible swappable batteries. It’s big, heavy, and expensive, but it’s also one of the most capable portable systems on the market.

Choose the JBL PartyBox 520 if you prefer something a little smaller that’s easier to transport while still delivering great sound and lighting. It’s more portable, lasts up to 15 hours on battery, and includes the same app features and input flexibility.

If your goal is to fill a large space or host outdoor events, the 720 is the clear choice. But if you want a slightly more manageable option that still looks and sounds fantastic, the 520 hits the sweet spot.

What should you get instead of the JBL PartyBox 720 and JBL PartyBox 520?

You still get big sound with strong bass, a customizable light show, and a telescopic handle with wheels to improve portability.
