Just found out my HD650s are the older version regarding the driver. They are absolutely like new, but must be quite old by now. The silver driver version has been around since 2007, right? S/N is 016993
EDIT: Been searching the forum. That S/N must be from around 2004, the earlier batches. Should've paid 89€ more and get a new pair, with silver screen drivers.
