I bought a pair of Romeo 1 in the late 1990's, (1997 I think), and still have them. To freshen them up I bought a full set of Linegear rubbers. When I have swapped them I noticed one of the original ear socks has "made in USA" but the other is completely blank and does not have CE which all others I have seen have. I am not concerned as I know they are original as they been in my possession from new but I just wondered if anyone else has come across this?
