I'm new here, but I have a Macbook Pro (connectors: 4 pole jack(maybe combo jack? I don't know the correct name) and usb-c (I have usb-c - usb-a cables) for my work and a PC for gaming. I try to find a device that can help me to switch between PC/Mac without disconnect my headset from mac to pc. First I checked the Sound Blaster K3+ because I can connect my Mac via Mobil i/o and my PC via Line in/out but maybe there is a better solution. Currently, I have a headset with mic but I plan to buy a standalone microphone. In my PC I have Sound Blaster Z sound card so for PC can live without USB connection. Thanks!
