I’ve experienced the same thing - I always right the microphones attached to earbuds were worthless, but compared to a laptop microphone, which picks up every last bit of background noise, my cheap ($15) earbuds’ microphone does a good job at only picking up my voice, with clear enough quality.

If you’re using Linux and Pulseaudio, look into echo cancellation, it’s easy to enable and can help improve your voice quality a little bit.
