I wear half inch white gold contoured ear rings in each ear in guy mode. I've had some looks, but only comment from one of my students, wow they look cool.
No comment from the rest of the people I work with. Oh one comment from a female colleague, "I see someone else has personal jewelry now" said jokingly (my research group is all female).
The only other mention was when I went back to a major department store and bought stuff. I went back a week later to buy matching things. The cashier said Oh I remember you ( I was in guy drab) I asked why, she just said you have really cute ear rings.
I've bought more ear rings at jewelers, and I recently treated myself to a pair of white and yellow gold danglers after getting some surprise money. Even though it was obvious they were for me, like I was holding them against my ear looking in the mirrror

there was no comment just nice talk. I looked at several pieces and the cashier had totally no problem, that she betrayed to me

In my experience most people want to ignore anyone who doesn't fit into their little group.
One after thought, If anyone asks why you are wearing ear rings, just tell them you like them. Stops any other comment
