Reverb from auditorium setting--noise canceling headphones work?

[rdemaris]

I am acting as a entry/comment monitor for a hybrid zoom/live-in-auditorium meeting situation. We have some 50 or so in live attendance, and they have opportunities to comment on microphones over the auditorium PA system. Zoom users can also make comments, which are the put out via the PA to the live audience. I sit in the auditorium and monitor those who are linked to the meeting by Zoom. "Standard" headphones still permit plenty of the amplified "live" sound into my ears, so reverberation is driving me batty. 

Wondering if noise cancelling headphones would do the trick to kill off the live sound, and simply let me hear the program and other zoom participants over headphones. Anyone have any experience with this situation? Can't afford much more than $100 for headphones--if they'd work. 

Thanks!
