A:Answer Yes, our JBL Partybox 710 requires a 3.5mm cable to connect it to other JBL PartyBox speakers via Daisy Chain that have AUX-in and AUX-out. You can also do this with other brands of portable speakers that have AUX-in and AUX-out. However, the sound may be unbalanced. For more information, we recommend checking with the manufacturer of your other speaker.
