5 most common Industry Standard Headset Mics

Hi everyone, I'm working on an academic project where I will be exploring how the shape of a user's head and torso influences the pickup patterns of headset mics. I wanted to research the five most common headset microphones found in professional settings. Which Mics have you encountered/used in the wild the most? It doesn't matter whether it's corporate, Vocal performance, theater, etc.

I was definitely thinking the DPA classics, but what else? Thanks for reading!
