> So you can make everyone else on the call suffer your horrible audio quality instead (room echo, etc.)?

No you're confused - the point is it's better quality.

There's no limited bandwidth, and it's physically a larger microphone than the very limited micro one in your headset. It picks up the same background noise that its geometry can't eliminate, and can do the same processing to try to remove it.

Not only that, many laptops and tablets nowadays use microphone arrays, not just one - so get better quality from that. Also there's no time lag. Half the people dialing into meetings in airpods at my company have a very noticeable delay for their audio to come out when they start speaking. It's difficult to not accidentally interrupt them.

I’m not confused. I understand the concept of the wireless bandwidth that’s needed for the bidirectional communication when in headset mode vs headphone mode. My point is that the laptop microphone arrays are just not as good as a microphone that’s designed to be right next to your mouth, or at least within 6 inches. The mic arrays on laptops almost always sound worse than headsets.

Those are tiny microphones in your headset, and there's only two of them, sending back a mono signal! A MacBook Pro has an array of three much larger, higher-quality microphones, with high SNR and directional beamforming and the ability to do proper noise cancellation. They're also on a hardware bus to your system. The microphones in a headset just don't compete.

Try it yourself!

All I can say is that when you’re on the other end of a call with someone using the laptop array, vs a headset, the quality of sound from the laptop array is objectively much worse than the headset. You hear room noise, echo, etc. It’s definitely not as bad as older laptop mics that didn’t have noise cancellation, etc. but it’s still worse than a headset.

Wouldn't the signal to noise ratio be better on earphones as they are relatively closer to your mouth and are "dampened" by your body as opposed to on a laptop where it's more likely to pick up keyboard/fan/environment noise as it's closer to those and has no/very little vibration dampening?

Doesn't seem to overcome the bandwidth or microphone quality - try it yourself! Quality is clearly better for me.
