I didn't pay attention to the orientation of the ear cushions when I removed them and I'm not sure what the correct orientation is for putting them back on. The ear cushions have a thicker part and thinner part (making them what AKG calls '3D'). I'm not sure where the thicker part is supposed to be placed on the earphone.
If you look at the inside of the cushion, there's a line drawn to indicate which hole corresponds to this thick part. What I'm not sure of is which notch on the earphone this should match up to, to get the correct angle of the cushion (there are nothces at 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock).
If anyone knows, that would be a big help, thank you!
