Xarq,
I'm really glad you're enjoying NightHawk, and thanks for the feedback. I can help clear up some confusion.
First, the smell is not the earpads, it is the natural aroma of liquid wood, a completely natural material.
Most people really like the smell (myself included). Of course, there will always be those who don’t care for it.
Fortunately for those who don't like it, the smell diminishes fairly rapidly over time as long as they are out of the case.
After a few days the smell diminishes by about half.
After 1–2 weeks, another half, and after 2–4 weeks, it should be mostly unnoticeable.
If one directly sniffs the inside of the earpad area after 2 weeks or more, there will be a faint aroma of liquid wood—which will have then matured to a more vanilla aroma (after all, one of the “top-secret” ingredients in liquid wood is vanilla bean extract).
Second, NightHawk is a sustainable, responsibly manufactured, and fully RoHS-compliant product; therefore, there are no plasticizers or harmful chemicals used (including PVC). I am extremely passionate about eliminating harmful materials in the manufacture of our products, and I believe NightHawk is the most sustainably produced headphone ever made. You can

Third, our pads are made from eggshell membrane-derived proteins, so it's a more natural material than regular synthetic leather. This particular leather was specifically developed to more closely resemble human skin, which means improved comfort. Further, this eggshell leather is much more durable than genuine leather. We made the decision to use eggshell leather so that the pads wouldn't wear out as fast as genuine leather and would require no maintenance. You can

Fourth, if you still want to make your own pads, the stock pads can be easily taken off the retaining frame and swapped out.
