Overview

The PartyBox 520 Portable Wireless Party Speaker is engineered for big sound and long-lasting parties, knowing exactly how to set the mood with an electrifying lightshow and JBL's biggest, boldest, thumping sound yet. The sound is powered by the all-new AI Sound Boost technology, designed to get everyone moving and shaking. While the sound is heavy, the speaker is easy to move thanks to its telescopic handle and wide, sturdy wheels, which are ready to roll whether you're setting up in the backyard or by the pool. Keep the party going with up to 15 hours of play time before needing a recharge¹. This speaker is designed to withstand the most raucous party fouls, as it is IPX4 splash proof², so you don't have to worry about splashes or spills. Connect to a mic, guitar, or DJ console easily with two XLR inputs. You can also take the party up a notch by pairing the speaker or linking it with other JBL Auracast™-enabled speakers for multi-speaker connection. Control your entire party right from the JBL PartyBox app. The speaker also provides seamless, high-quality audio connectivity and powerful JBL Pro Sound and lightshow. Finally, the packaging uses recycled plastic and FSC certified paper.

Excellent sound and features. A little surprised that it was not significantly louder than my JBL 310 speaker especially for the considerable more money it is. Overall I'm happy so far. Connection to the JBL sound-sticks is an awesome feature!

Great features and sound

I just received my speaker yesterday and played it all night. That speaker is a beast. I have owned a JBL party box 300 and it’s no comparison to this speaker. The sound is crisp and distinct. I recommend this party box with no reservations

I bought it a week ago go. So lovely. It is a bit heavy. Music is crisp clear with the bass booming. Bluetooth connects easily. It can pair with other JBL party boxes with use of one button. Battery life is good.

Excellent speaker

Theford17 . 5 months ago

The speakers bang! I have no regrets with the purchase I really wish the USER MANUAL was in the package though. The quick start guide just doesn't cut it. Thankfully I was able to locate a PDF of the user manual and get it printed.(The speakers have different inputs & knobs on the back that you need to know how to use correctly to enjoy the most out of the speakers...and also not damage them. Read the user manual

TOP NOTCH SOUNDS

Cully . 6 months ago

Amazing. Best battery powered PartyBox I’ve owned. Huge step up from the 300 that I’ve had for years with no issues, I’ve just decided it was time for an upgrade. 10/10 would recommend.

[This review was collected as part of a promotion.] This product is absolutely amazing! I used for an outreach service for my church. We connected it to a sound board for outside use. The sound was amazing. It carried through out the neighborhood. The voices and music was clear without static

Nelly_Nel . 7 months ago

Yes, I'd recommend this product.

[This review was collected as part of a promotion.] This speaker is Way bigger than I expected. Because of that, I love that it has wheels. I’ve been using this speaker every day for the past week and a half already, I can tell you that this is game changer. First off, we all know JBL is known for the lights, and I love that the lights actually flow with the beats of The songs. It makes you feel like you have a party in your bedroom lol. I haven’t taken it out to the park or anything, but I can tell you that this is perfect for family gatherings at the park, concerts, karaoke, celebrations, etc. it gives you the options to Increase the base levels and adjust the lighting to your liking. Also, there’s another section of specifically for the microphone Part so when you do karaoke, you can adjust the volume based treble and echo, To your liking. It does have features Like checking your messages with your phone, which you will see in one of the Photos I’ve added. Overall, this is a 10 out of 10 and I say that about most speakers I get from JBO but honestly they are really that good. This is coming from a true music lover. If you’re someone that hosts big parties or block parties celebrations or anything like that this will be the perfect speaker for you. Honestly, it’s super loud like I said the bright colors are really nice and a sound quality is amazing. I expect nothing less from JBL.

BIG Sound BIG Package!

Frankowitz . 7 months ago

Yes, I'd recommend this product.

[This review was collected as part of a promotion.] OK, this is a BIG speaker, with a BIG sound. If you have heard, or own, any JBL products you know that GREAT JBL bass sound and the PartyBox 520 has the same sound. It WILL fill big spaces, like a pool or deck area. It would also be great to have in a party room or for a yard party. Operation and connection, using Bluetooth, are simple; it uses the same sound effects as other JBL products to confirm things, including Bluetooth connection. When those itty-bitty speakers say that they “have a big sound….” THIS is the sound they are talking about. That said, it also performed wonderfully at lower (living room) levels for me. It would also be great as amplification for a podium Microphone or two. There are two XLR inputs, one for Line in, on the back with adapters for Stereo plugs…. perfect for an instrument and microphone if you are a performer on a Patio or medium size club space. It also takes USB-C and a mini-plug Aux input. On top are controls for Microphone input, including bass, treble and echo. According to the specs, the Party Box 520 is ‘Splash-proof’. It’s powered by a JBL battery that is replaceable, it takes about 3 hours to charge, also according to the specs. Mine was 50% charged when delivered and I charged it overnight before use. First Thing: I strongly encourage getting the App for control of the PartyBox. There are features in the app which allow customization, including a seven band Equalizer with other presets and different types of Bass Response. The App is also the only way to update the speaker’s firmware, something my app did automatically on the first connection. I presume that JBL will update firmware, and the app, as different options are enabled. Effects Lab in the app is where the sound effects originate; one time per push. The app allows customization of three separate Sounds that play from buttons on top of the speaker. All the lighting settings are on the app, and it’s the same thing, you can set up your faves to play via controls on top of the speaker. It’s also possible to turn all the lighting off if needed, via the app. All this BIG sound, Big Control and BIG fun comes in a relatively big package, as tall as the average 4-year-old, and heavier. There is a pop-up handle and wheels for portability. If you want to lift it, I suggest getting a partner. But for someone like a music therapist who travels within a building, it would be great. Let’s get some actual usage. The JBL Party Box 520 is perfect for a pool or deck party, including music performances and/or Karaoke. Included with the sound effects are a few record scratches to use and some encouragement shoutouts. My favorite sound effect is the applause… I have that programmed into the “Thumbs Up” button on top so I can congratulate my kids after they sing. The lighting effects are great for a night-time yard party. Recently, I observed a Party Box in use as the primary sound system for a gym sized room and it was just fine - that bass really carries the sound.

Will a boombox 3 pair with party box 520?

Answer from Customer Support3 months

Thanks for your question. Our JBL PartyBox 520 and JBL Boombox 3 can not be paired together as they use different wireless connections. Our PartyBox 520 features Auracast, while our Boombox 3 uses JBL PartyBoost. These two systems are not compatible. To connect multiple JBL speakers, they must support the same pairing protocol.
