JBL Partybox 310
I have paired two Partyboxes 310 via TWS. The music comes out of both boxes wonderfully. When I plug in a microphone (e.g. the JBL Wireless Microphone Set), the vocals only come out of the speaker in which I have plugged in the microphone, the music continues to come out of both. However, I want music AND vocals to come out of both boxes. Is this not possible at all?
