After using these for about 2 months, I really don't like the stock cable. I'm not sure if there is any memory wire, but I have a hard time keeping the wire from flaring off my ear rather than just having them wraparound like I do with my Shures. Even with the pre-shaped guide I still have trouble keeping them curved around my ear.
ChurchillWUsed mined almost daily from the drop, my job involves a lot of outdoor walking, sound great with the foam tips although I do have to triple look crossing a road! I picked up a cable on ebay for about £22(less a £10 voucher they mailed me) delivered, still a bit stiff but it removed the control block which hindered my round the ear use.
