So I removed the RCA adapter and plugged the 3. It is from the Nassau Coliseum 5 night stop but it from a different night. When using, I do not have sway or metal on metal sounds. My feet had started to hurt recently and I was getting corns on the soles of my feet. I am sending them back and I may try the smaller size 4/5 this time. You have to be careful though, they get too loud. It helped me solve this issue. My g230s are just wrapped in perforated fabric, which makes it a tad itchy. Most importantly, it does not irritate my eczema. Good choice!
