Its time to party

[This review was collected as part of a promotion.] This is my first PartyBox type of product. I was a bit surprised how large and how heavy it is. But JBL does make smaller models, so I guess at 400 watts RMS, this is to be expected.
Setup of the PartyBox 520 was a breeze - press the Bluetooth button on the top panel, and seconds later, my iPhone was paired.The JBL PartyBox app (a download from the app store) is very simple to use. Turn the light show on/off and select the patterns. Alter the eq. Adjust the volume. Its all right there. The top panel also has simple controls for volume and light show controls. JBL typically gives you a very limited user manual, but this one is better than others I've seen.
Now for the most important part - how does it sound? I streamed music from Spotify on my iPhone, and the sound quality is incredible. It's REALLY powerful, and it can handle being turned up 1/2 way without undue distortion (it was just too loud for me to turn it up any further). There is a top panel control that lets you pause and start streaming without needing to grab your phone.
The PartyBox 520 also has inputs for mics or guitars, etc. There is a drop down panel on the back of the 520 that reveals controls for these inputs. I did not test this capability.
A really cool feature of the PartyBox 520 is the internal (and removable) battery. It lasts for 15 hours. of play, and can charge in just 3 hours. You can also run the 520 on wall voltage too of course.
This thing does everything you would expect and it does them very well. So why didn't I give 5 stars? Price. Not that it isn't worth the price, but it is a lot of money. But I don't think you'll find a better device in this class for less. I would have given 4 1/2 stars if that was an option.
All in all, if it is in your budget, I highly recommend the PartyBox 520.
I would recommend this to a friend!

This PartyBox is unreal!

[This review was collected as part of a promotion.] Wow! From the sights to the sound, I am blown away. The battery life in this massive party box keeps up with demand and is removable. This thing is loud! The bass will rattle my windows without compromising clarity. Even if I have either version of the bass boost turned on I still have high quality sound that’s clear. I love that it connects to the JBL PartyBox app and allows for detailed control of the equalizer. I can fine tune the equalizer to enhance the sound for any situation. I personally think the Party Buttons are a little silly and an unnecessary feature but to each their own. Lastly, it is large so it is heavy and while the wheels are a great feature they are smaller so you just have to be aware of that and whatever surface you’re rolling on. As a 5’ 4” female it is a little bulky to maneuver around. All that said, it is a high quality speaker that is premium in the way it looks and feels.

[This review was collected as part of a promotion.] This speaker is a BEAST!!! I used it for a family cookout and i swear you could hear the music throughout the neighborhood. The sound is crisp and clear, the bass is deep and perfect! Would definitely recommend to anyone in the market for a speaker.

You need this if you party!

[This review was collected as part of a promotion.] This thing is awesome! I was very skeptical of the party box line, but I am a believer now. The 520 is absolutely amazing. It’s not just a speaker system, but a true music experience. JBL sound quality, massive sound, and lights! The entire family jammed out for hours the first night we had it. Outside, the sound carries a very open area clearly. The 520 is fantastic for outdoor parties, pool days, and night parties are that much better due to the lighting effects (kids absolutely love it!). This is now one of my top 5 JBL favorite items ever! If you need big sound, the Party Box 520 is a no brainer.

All-in-One speaker w/ JBL sound quality!
on July 14, 2025

[This review was collected as part of a promotion.] First off, the sound is incredible! It gets loud, but also has the JBL punch and clarity you’d expect. Make sure to pay attention to the size and weight specs as this is a very large device.
It’s also an all-in-one setup for DJ’ing, karaoke, parties, or a shop/garage speaker. You can play sound effects (air horn, cheering, booing, etc) and control the lights, colors, and patterns via the app or the top of the PB520. This is a feature-rich, do anything kind of speaker, so I’ll try to cover as much as I can!
The wheels and a sturdy, collapsible luggage-handle make it easy to move around, and there is an integrated grip/handle on the bottom in the front to assist in lifting.
The back of the PB520 has a battery compartment with easy access for quick changes, a covered AC socket for the power cable, and an accessories panel. The panel has 2 microphone ports, each with a separate gain, and the 2nd one can also be used for a guitar. There is also a USB-C port for charging devices and a 3.5mm Aux In port. This panel also has ports to daisy chain compatible Party Boxes.
I spend a lot of time working on cars, so having tunes is a must. Smaller speakers can easily be overwhelmed when trying to play above fan and compressor noise, but the PB520 does NOT have that issue. Controlling it from my phone also makes changing the volume or music source a breeze.
I can’t speak highly enough of the PB520. It’s awesome!
I would recommend this to a friend!
