Review on Sennheiser PC 8 2 Cancelling Microphone by Mark Holloway

Updated to add: I am back in my office and have a window on a very busy street with lots of noise. When I use this, my students hear almost no road noise. The ambulance pulled up to my window at full volume and they barely heard it. I started teaching college classes from home and using Zoom for my classes. Many of my students can't attend, so I'm recording my classes. I also need to copy my recordings to be ADA compliant. With my other headphones or just the computer/camera mic, I spent more time fixing CCing than I did in class. These headphones and mic are great! When copying, there are practically no mistakes. When I listen to music, it's like surround sound. Good product!
