It was only $30.
And the reviews were great.
And its compact size would fit nicely on a gooseneck microphone stand just above my keyboard, but out of sight of my webcam. So I had to give it a try.
Here's the two products in use:
👉 Fifine K669 Microphone: Check Current Price on Amazon
👉 Gooseneck Desktop Stand: Check Current Price on Amazon (very important for placement)
The short -- I was very impressed with the Fifine k669 microphone. The audio quality is pretty damn good. Certainly the best you will find until you get up to the $100 price point.
As with any microphone, placement is very important. The little stand that comes with the microphone itself is basically ineffective at getting the microphone into a good spot. For that reason I recommend using a gooseneck mount which can be had for less than $20.
Alternatively if you don't want to buy the gooseneck or want to keep it 'simple and minimal', the Fifine K054 is a gooseneck microphone for $20 which is pretty damn good. You can check out my test with that microphone here in my video on Best Microphones for Zoom less than $50.
Really the only complaint I have about the K669 is that the cable is not detachable. So when threading it onto a mount you have to move the cable with it. Just a minor inconvenience.
