One thing that is absolutely essential is the pads.

Purrin, if you happened to have any (Grado) foam pads lying around, or if you could get hold of cheap pleather headset pads that fit the cup diameter, you could also highlight that.
I tested those and my ears told me that it is exactly the pads I used that give the best response.

PS: Marv, consider these StratoKOSSters yours. I planned from the start to give them to you as a little thank you present from one audio enthusiast to another for your being ready to do the measuring. I would never think of doing this if the Stratos were crap, now I can let you have those with a clear conscience and glee in my heart.
