Hello, I recently purchased a pair of Shure SE215 online and they came in this box: http://s90.photobucket.com/user/ofey_s/media/Shure/SE215-01.jpg.html From what I have read this version is the "international" version. If I am correct this is the U.S box: https://images-na.ssl-images-amazon.com/images/G/01/musical-instruments/detail-page/Amazon_SE215-CL_img10_lg.jpg Is this a problem for me as I am based in the United States? And is there a difference in the manufacturing?
