Questions & Answers

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.
