Review on 🎙️ TanGuYu Super Mini USB Computer Microphone Mic - Driver-Free Audio Adapter for PC Laptop Desktop Mac - Ideal for Chatting, Recording, Skype, YouTube, FaceTime by John Banks

They're so bad I can't even think of a use for them. I got two because I wanted to use them in an audio project with some Raspberry Pis, but the signal is so bad/weak that they're really useless for anything other than detecting very loud noises. I've also tried them on my MacPro and they were just a little less terrible than the Pi. Some reviewers seem happy with them so I may only have two really bad ones but the ones I have are terrible.
