JBLPartyBox 520 Portable Party Speaker

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

Unbelievably the best!

What an amazng speaker, loud enough for room full of 60 girls singing along at home but we also took it into the garden and the sound was the best we have heard no fuzzing clear and loud, most definately contributed to an amazing party, the music and sound is very important to create a great atmostphere this did not let us down, dont wonder ... do it!

What an amazing speak with amazing sound quality

I received this speaker in exchange for my honest review and it’s absolutely amazing. The sound quality is fantastic and so clear . I must add it’s bigger than you actually think and quite heavy to but don’t let that put you off how good it actually sounds. The light show is a nice added extra which can be switched off if you require and the app you can download with the speaker is so easy to use and offers a load more options for the speaker

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.

JBL party Box 520

I have many JBL products and The JBL partybox 520 is new addition to my collection. It's a fantastic product if you love outdoor parties and like quality sound. The JBL PartyBox 520 is also perfect for use at home, delivering an extraordinary musical experience for everyday use. There are so many choices of light patterns and if you are having a night party it just look super cool. It’s easy to connect to Bluetooth. Over all i would give this 10/10. JBL has never disappointed with their product.

Great speaker

If I had to sum up: the JBL PartyBox 520 is a beast of a party speaker. It manages to deliver enough power to impress and enough clarity to satisfy when you're not just blasting it. It’s not perfect, especially if you expect perfection at every level, but it does most things very well. For me, the joy came from cranking it up with friends outside, watching how it reshapes a space with sound and light. It’s not subtle — it’s meant to be felt. If you value atmosphere, want something tough and loud and don’t mind paying for it, it’s hard to beat. If instead you need something more subtle, lighter, or cheaper, there are trade‑offs that might make a smaller model more practical. You’ll love it if: You throw parties often, indoors or out, and want something that feels like a centrepiece. You care about atmosphere: lights, rugged design, and the “wow” factor really matter. You want a speaker that’s flexible: mic/guitar inputs, replaceable battery, heavy duty enough for regular use. You don’t mind sacrificing some portability for power. If moving 25‑30kg is doable for you (or you mostly roll it around), the tradeoff is worth it. The lighting effects are a lot of fun. At night, they turn the speaker into an event by themselves. The front bars, strobes, the ambient LEDs – they add atmosphere. Not perfect for every scenario (won’t help your neighbours’s sleep), but when you want a party vibe, they deliver. he connectivity is solid. I liked having dual XLR/¼‑inch mic/guitar combo inputs – if you want to sing, plug in a mic, or throw in a guitar, or even use a mixer, it’s ready.
