I have been trying to figure out the history of the Sennheiser HD 25 and the various models that have been released: HD 25-1 II, etc. It seems quite complicated. It's impressive that the original Sennheiser HD 25 was released way back in 1988!! It seemed to make a big impact then as studio monitoring headphones, and more recently the Sennheiser HD 25-1 II has had a big impact as DJ headphones, among others, winning multiple awards like the DJmag Tech Awards for Best Headphones.
 
I am not exactly sure how the models have changed and developed over time, and what aspects distinguish the HD 25 from the HD 25-1 II, or other models. Would love to hear from those who know the HD 25 history.

Huh?
 
This article has some history, if that's what you're looking for Navermyr. The OP's been long gone.

I believed the HD25 was introduced in 1988, Tyll says 1987. He's mostly reliable.
 
Gonna find a pair of old HD450/480 released at the same time for 10-20 bucks and do some modding. Figure they've got the same 70ohm drivers as the original HD25.

Thanks Head Injury and Navermyr. Great link on the history; that was a big help. Looks pretty consistent. I really have to save up for a pair of these.

is it true the adidas "originals" version is the 25-1 ii? or the original 25-1? im seriously considering getting a pair for portable use but want to make sure i have the most up to date version.

There is no difference in performance only in the accessories.
