I have never heard of anyone having problems wearing sterling silver earrings...but these ones, they hurt my boyfriend's ears really bad.  I assume whatever they use to fill the silver with is very bad stuff.  I tried them on and instantly my ears got hot and started burning!  I also have sensitive ears but even the earrings with copper in them don't burn my ears like these did.  If you have no allergy problem with metal, it's probably a great pair of earrings.  They do look really nice, pretty big stones, give you a nice luxurious look.
