quiero comprar uno pero no tengo mucho presuspuesto

Might be the wrong sub apologies if that's the case.

TLDR, found a Audio Technica DR-2700HE on FBM for $15 and need help learning what equipment and how to adapt it for use on my computer. All hypothetical at the moment.

I am looking at a Audio Technica DR-2700HE on facebook marketplace for 15 dollars at the moment. My pc headset mic died but the headphones are still good, I'm using a second worse headset with a functioning mic laying on my desk as the mic at the moment. The main question is, is this worth it, second being how feasible and for what price. I'm in the US the budget is probably around 25-50 dollars depending on what's needed. (this is not including the microphone)

Thanks for the help and if this is the wrong sub please point me in the direction this question is better asked!

Title. I play games with friends on a laptop with a cooling pad underneath, and said cooling pad has a 6-inch fan going at 2800rpm, which is pretty loud. Does anyone know any microphones that are good for blocking out consistent background noise like that? Thank you!
