it is called "public mold" and sennheiser bought them from foster back in the days , and u could find them with all kind of portable md/cd players back in about 20 years ago~ but all our drives are our own design ~ just too poor to get a new shell~ you know how it is with internet start-up companies~ ( like in south park lololol)
That's cool. I think it's great you did that. In no way was it a slam against you for doing it. Just interesting to see. Thanks for the info. Do you make a version with inline controls for iPhone?
