Hi!
You probably all know the great budget headphones from Koss.
I bought a KSC75 about 3 years ago, but was never impressed by the sound signature.
When I was cleaning up the last days, i discovered it hidden in a small box and remembered
a post on reddit. Wouldn't it be nice to transplant the small driver into a larger housing?
That sounded like a great idea. So i started Fusion360.
This is always a lot of fun and there is nothing nicer than starting your 3D printer at a room temperature of 25 degrees (77 fahrenheit) to heat it up even more.
At the end the KSC75 x Grado headphones were born. Easy to print as well as easy on the head.
The clamp force cannot be compared to an original grado. Very pleasant.
Now let's get to the most important part. How does he sound?
I like the signature very much. The highs are crisp and clear. Due to the very light clamb force and the slightly thicker earpads, the soundstage is larger. The mids are taken a bit back .. sadly.
The deeper tones are still very thin and drop off very fast around 100 Hz.
Overall, I enjoy it a lot more than the original KSC75.
If you still have an old Koss lying around and a 3D printer, you should definitely try this modification.
Have fun rebuilding.

Before the question arises where you can find the stl file for the headphone stand, here is the link. In my pictures you see XL version.
