I now pronounce stratoKOSSter v1.5 the best sub $20 dollar headphone mod EVAR!!!!! Stay tuned for details. Incredibly neutral sounding.



Changes to mods:
  • Removed cotton stuff and replaced with medium density packing foam
  • Placed drivers to rest on top of the cup (with pads resting on top to keep them in pad) as opposed to pushing the drivers inside.
These are it. Incredible sounding!!!

CSDs. First set of L+R are original. Second set of L+R are mods.

I KNEW IT, my other sets tell me the same!

Marv, thanks again for carrying out the measurements. I guess people will understand now that I called these little gems.

I know people will call it blasphemy, but since I developed the StratoKOSSters I have very rarely given my Symphones Magnums and HE-500's any head time.

I'm listening to these over the TH900s right now :-) Way more neutral. Will post pix of what I did.

Slow cap for you both. That's a very impressive mod of the KSC75. I really want to scrounge together the parts to put one together myself.

I am extremely delighted, because now people (myself included and those who are open to measurements) have objective proof. I knew from the moment I put my hands on the open wood shells and thus closed them that I was onto something. When I modded the Grados, I also knew, but only that I could not change much for the better.

Pix.
  • Driver resting on top of cup (rather than being stuffed inside.) Closer to ears - more bass.  Increased volume inside cups, less direct refraction and reflection off side walls = no dip at 200Hz.
  • Foam stuffed inside cups. Works better than cotton to absorb reverb. May want to try memory foam for greater effectiveness.
