Na they won't stop making them. They will just throw in new housing and cords and call them by a new name. I don't know if you followed this entire thread but yes. Philips is very guilty of reusing the same drivers and do minor tweeks to their drivers via new housing and such. I kinda don't blame them however as they have a great driver in the one they have in the SHE3580. Very solid sound for a smallish driver.
It all stems from the older SHE9700.. I am certain the same driver then went into the SHE3580, and now the SHE5105... All 3 have a very similar sound yet slightly modified with tweeks on each.
