Here are the few parts you need for the full mod.Would you mind pointing me to this mod? Thanks!
-Stax Cable Mount 5 Pin Din Plug (I bought mine from Moon Audio)
-Heat shrink for the plug (Don't need this if you don't mind your adaptor looking shithouse)
-Vesper Audio angled earpad, mine are all lamb skin with memory foam. About 1 inche thick with thinnest side 3/4 of an inche
Steps to the MOD
1. Carefully remove the old earpads. Burn them to avoid temptation to put them back thinking you'll get a better sound.
2. Remove the foam that's covering the earspeaker. If you're careful you can undo this mod (No idea why you would want this)
3. Install the earpads with the thick side facing you as you put them on. (Refer to photo)
4. Cut the Koss 950 extension cable and solder on 5 pin Din. (Start up your car and drive over the Koss driver a few time. Because after you connect the Koss 950 to a better driver, you won't go back)
If your don't have soldering skill ask someone to help you or you can always buy them online
Optional seal the vent if you prefer a warmer sound. I like to leave them open. Do one side only, you notice the difference in soundstage also.
With foam removed
With foam intact
Well that depends if you remove the foam that's covering the driver. If you remove them then no, I wouldn't call it dark just lift the needed bass a lil.Congrats with your finding. Will the thick pads make the coloring of the sound darker?
These are the two track I mainly use to audition the changes
