Have you ever what a Boxing Match ... and the Ring Announcer is holding, what looks to be 2 Microphones in hand ?

Well, it is 2 microphones ... strapped together.

Notice, He'll intentional speak into only One of the mics. For reason.

The 2 mics are usually the same brand. You could use something like an SM57.

The 'trick' ... one of the Mics is 180 wired out of phase [Reversed Polarity].

Any sound hitting both mics [the room sound, or if your class lecture draws a noisy crowd], that sound will be NULL'd.

Speaking into only one of the Mics will allow the signal to 'pass', be heard.

Maybe something that would work.
