Do you want the best headset? 
Noise on Teams calls or meetings can be very distracting and frustrating when you're trying to have a productive conversation. Teams noise suppression helps stop this problem so you have a better audio experience.
That being said, if you have Teams noise suppression at max, there's a trade off of reduced microphone quality. If you're in a quiet environment and the best microphone quality is important to you, then you'll want to turn noise suppression off.

Important note
When using a wired or wireless headset with a noise canceling microphone, with Teams noise suppression "on" it can do the opposite of what you want, or cause very bad microphone quality. If that happens, turn noise suppression off.
Also, if you use Windows with a headset that has a noise canceling microphone and it seems like to much background noise is being picked up, follow this video and disable Intel Smart Technology to see if that helps.
