Before I figured out how to don the KSC35's, I was holding open the unattached part of the clips and then trying to rotate them onto my ear. I've now come to realize that this is the hard way to do it. The easy way for me now is:
1) Hold the headphones with the thumb on the unattached portion of the clip (the side closest to where the wire comes out of the driver), the middle finger and ring finger on the portion of the clip that is attached to the driver (i.e right where it starts the half circle, on the K side of the Koss logo), and the index finger on the top of the headphone itself.
2) Use the index finger to angle the driver up, thus increasing the gap between the top of the headphone and the clip.
3) Place the clip right against the side of your head, and slide it down over the top of your ear, through the increased gap
4) Adjust the fit. Pull the ear through the gap if need be, rotate the clip so it's more comfortable, etc.
Takes 2 sec per ear.
But as they say, YMMV...
