A:Answer Thanks for your inquiry. Your setup won’t work as expected because our JBL PartyBox 310 and 710 cannot connect wirelessly to each other. To make it work, you would need to connect the 710 to both 310s using long AUX cables, but signal quality may degrade over 100 feet. Another option is to use a long-range Bluetooth transmitter with receivers on each 310, or you could use a DJ mixer or audio splitter to distribute the audio signal properly. If you need more help please contact our customer support.
