In stock form, it is my firm belief that the Koss KSC75 is one of the best headphones under $50, portable or not. Here are a few incredibly simple mods that give it a bit more flexibility and further dynamic sound:

First, you have the stock '75:

Follow this link and order one of these "mini headphones". The picture on the product page is crap, and you don't notice that the headband uses the same snap-on attachments as the clips on the stock can. What you end up with is this -



I plan on modding the headband itself for more comfort - a future endeavor. Interesting to note that I do believe this mod makes an impact on the sound; the extra clamp provided by the headband puts the drivers closer to your ears ever so slightly, which brings out bass and fills out the sound. Subtle, but beneficial.

This mod is very close to s1rrah's shack hack. Simply put, you punch holes in the foam (I used a standard single-hole punch) in any pattern that you wish. For the size of the foam, I felt three holes on each side was sufficient. Sonic differences are not massive, but as with any open or semi-open driver it added a sense of clarity and removed any noticeable veil that may have been present.

Credits to Kramer on Head-Fi, we have another set of simple mods that can be performed. I have not done these myself, but I plan to at some point.

Yup, short and sweet. I will be updating as I explore Kramer's mods and headband work.

For a headphone that costs next to nothing and can be used anywhere, this is about as good as it gets.
