Hi @Mennyt , if you are looking for a cheap one then NK STAR USB 2.0 Mini Microphone will do the job well, or if you need better audio and special Audio processing algorithms includes VAD, DOA, Beamforming, NS, AEC and KWS you try the Seeed Studio ReSpeaker, also keep in mind normally USB Webcam has the built-in MIC and you can also utilize that too.
All the best with your project, Happy making.
