Haha, just posted it at the same time you posted picts.
Are those yours? Well i can tell you they are NOT the new version. Look at the chamber of the new one:

If i were you I would contact them... Looks quite suspicious to me...
EDIT: I have the "vintage" version and the chamber is the same as yours, but mine ends on 1/4'' plug. You might want to look at the color of the back of the driver. Check below the number to see what color it is.
EDIT 2: Was the box sealed?

) you might want to wait for other sr225 users, because maybe there was a version of sr225 with 1/8'' plug...
