i lost the cable (aux). now it turned out that NOT all 3.5mm fit in. i tried the one from beats and others today at MM. none of them fit in. then i was advised to order an original one from sony, which would be extremely expensive. apparently the original one is narrower and that seems to be a problem with the universal ones. now to my question; which cable can i buy that would be 100% compatible with sony headphones?
