From the looks of it on here around 40-50. Just asking because I know somebody who has a pair for sell. A little paint on them not sure it its stains or just dirty but I have a white and black marker so I could touch them up if needed. Overall I would say 7/10 as far as condition. Definitely in good playing shape.
Also how do you tell if they are Pro or regular I3s?
i collect white i3 frames and i have always found them for 35-45 shipped depending on condition. they would sell for 45 if the nose clip was in tact and the foam was all there and in tact (glued on doesnt matter since you can just re glue them)
