What type of jewelry do you guys wear in your tragus? I really don't like the one sided barbells that most people wear (one side is flat, the other has a ball/stud) because its not symmetrical! [my OCD maybe].. I've been wearing tiny plugs with O rings but they get in the way of my Ipod ear buds. I wish I could find some short [symmetrical ] barbells.. Or seamless hoops? Has anyone tried those? Not sure how they work
