@depglass -
I do think it depends on who makes them.
I had one from Judith Ripka and had to return it because it hurt so much.
So I knew never to order earrings from her.
Another I still have and love from a designer on QVC who is no longer selling here, (forgot the name), are very comfortable and very secure.
