IK Multimedia iRig Stream Mic USB, it sounds great, has a built in audio interface, pop filter, direct monitoring, mixing, light up mute button, and all for under $100.

Def use the mic with a pair of wired headphones/earbuds to use the live/direct monitoring feature.

My team used to have a lot of issues with people mics being too loud or too quiet without realizing. Getting everyone on that mic and specifically using direct monitoring has solved that issue.
