    Great speaker

    The JBL Partybox 520 is a great speaker. The size is perfect and portable to take places. The sound quality is amazing and light quality at night time is bright. I like that it has a USB C port to charge your phones. Its a pricey speaker but hopefully they dropped down the price.

    Big and powerful

    Great powerful sound. Of course JBL quality. It's quite heavy to pick up and put on the speaker stand. Definitely louder than a 320 but if you have 2 320 as a stereo. The stereo is nice. I purchased 2 320 for the price for the 520.

Questions & Answers

  • I have 2 320 speakers running in stereo . What happens if I add a 520 ? Do the 320s stay in stereo mode ? What mode does the 520 go into R or L side ? Or do they all play the same ?

    When you add a JBL PartyBox 520 to your pair of Partybox 320s, its connection switches from Stereo Mode to Party Mode via Auracast. Adding a third speaker means all three speakers will play in unison. Our PartyBox 520 won't be assigned to left or right, however using all three together gives you much louder, fully synchronized sound to fill a larger space. Feel free to contact our customer support for further assistance.

  • Can the JBL 520 connect to a JBL 310 PARTYBOX

    Thank you for your question. No, our JBL PartyBox 520 cannot be wirelessly linked or stereo-paired with the JBL PartyBox 310. The PartyBox 520 uses JBL's newer Auracast technology, while the PartyBox 310 uses an older wireless pairing system, so they are not compatible for wireless speaker grouping.
