Review (5/5): Awesome for teachers to try!
These are awesome inventions especially for English teachers who have to read a lot out loud and need their voices to be clear and heard by all students. With that said the only drawback is that your face will sweat. I found it best to use these along with disposable masks because they seem to absorb the water that you sweat. When I have to read a lot with these I changed my mask a few times a day but my students can hear me clearly and I’m saving my voice because I don’t have to talk as loud. If you’ve never tried These give them a try. Several of my coworkers and I gave them a whirl and 80% of us loved it the rest thought they were so so and mostly use them when they have to talk a lot to class.
