I hope this isn't evidence that the virus, or reactions to it, are already affecting us in significant ways, but (1) If the virus is capable of each airborne transmission, I don't see the sealing, filters, and/or forced-air arrangements that would be necessary to protect against that. (2) I also don't see anything about the acoustical damping properties of these. If they are designed to let stadium noises in and out (so one can cheer on one's preferred team and listen to others doing so), they are probably useless for echo cancellation and acoustic feedback damping. Other than that, great idea, especially since it comes in a choice of colors. john
