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.

Tried the regular bowl and TTVJ flat pads. Your pads by far were the best. It wasn't even close.


Woohoo! Yay! Thank you for the gift!


I can post results on HF? This is too good not to let others know about.

You have no idea how surprised I am. The stock cable is so short than I am bending my head toward the amp in order to listen to it while I am typing. Very uncomfortable with my head tilted 15 degrees, but you guys know how much a priority I put on something that's well behaved in terms of FR.

Doesn't sound so bad. Just type in italics  8)

I was about to ask you to do so, but please post the results in my thread on Head-fi, where I introduced the mod and also provided a picture tutorial for making the pads.

I have already recabled all my other Stratos, I just sent in these with the stock cable to point out that the cable is of no importance for the sound just for comfort and fancy looks

I though about trying something like this myself before but I always figured that the plastic frame (which the diaphragm is actually mounted to so it's not to easy to get rid of or cut away) would hold it back too much.  I guess I was wrong though.

I'm going to have to try this sometime.

Will do. I'll write a funny review similar to the HD700 one with comparisons to comparable headphones, SR-80, KSC35, HD700, etc.
