Sounds like what you need is INPUT to your laptop...not output. If your laptop accepts a mic input on your headphone jack...most new laptops do...or have a separate mic 5mm then you can use this for one 1/4" input then use the wireless mics on my 2nd link where it uses a single input for the two mics....the wireless mics are inexpensive but they'd good. I have 6 of those mics. https://a.co/d/02U0zGIp https://a.co/d/0buNxzGm
