Wireless accessories for online teaching in Teams

Would like your technical advise on the improvement of Teams online teaching for our campus.

Recently we have feedback from our online students that they couldn’t hear our lecturers clearly since our lecturers rely on the laptop built-in mic.

 

So my college director is asking to source for a wireless clip-on microphone but I checked around and it mostly requires either USB-C or audio jack connection

 

so would like advise & recommendation based on what other educational institution is using for their online teaching
