So I picked up a pair of almost mint, two minor nicks I can find, HD650s from a reputable individual for $150 shipped and they arrived today. After thorough inspection I'm very impressed with my purchase but this part gave me pause.
Printed on the driver is 06.09.07 and then HD580 on the next line with Sennheiser stamped into the cone. Is this really the 650 driver or is it a 580 in a 650 shell?
I'm not without recourse, I can do a paypal dispute or a cc chargeback but I'd prefer it if I could verify first.
I've read before in this thread that they're supposed to be like that, I think they actually are 580 drivers in a 650 but I never understood the difference, that being said I haven't given it much thought anyway. Can someone else confirm this please? I hate to see someone confused like this, I hate it when I'm like that. Vinyl is a b*tch like that! I always have a feeling something is wrong and I'm tearing up my records...
