I'm an engineering professor and have enjoyed purchasing these for myself, colleagues and students. They're just the right size and beautifully made. I love wearing them and my students seem to as well - one student has been wearing them every time I've seen her since.
I love this set! I wear them all of the time! For my ears I have to use disc backs do that they lay flat against my ear lobe. I think people can see them better this way!
