Hi Jay
I am Dave, an Independent Advisor, I will help you with this . . .
Most modern laptops only have one 3.5mm port, that is a headset port and can take a headset with a microphone, you need to buy a small lead that will convert that port to headphones and Mic
That lead is a 3.5mm 1 male to 2 female splitter as shown below, you can then connect your Mic to your laptop . . .
Please Note, the plug end (indicated below) must have 4 metal rings, not 3
