There are a couple main issues that people will have that demand different levels of solution:
- Multiple-speakers (like a call): The key here is to wear headphones. Otherwise you are subject to whatever noise-cancellation the platform offers, and any noise that other participants make will destroy your audio quality temporarily as it plays though your speaker and into your mic.
- Background noise or echo: In this case you want a directional mic. You want something that gets close to your face and cuts out the each or background noise.
If you don't have any of these problems (For example you are giving monologues in a quiet non-echoey room) than any decent mic will do the job. Many higher-end laptops even have sufficient mics on them (for example Macs will pick up everything in your house, but they will pick it up at fairly good quality)
