I came into a pair of L220s for a price that was very reasonable, IMO. I knew that the foam surrounds need to be replaced. In looking at the LE14A, I guess I was expecting some type of lip for the outer edge of the foam surround. However, I am just seeing where it was kind of attached to a spot maybe an 1/8 or 14 inch below the surface of the frame. My question is this. How do they ensure a good even fit all the way around? Without a lip or going on part of the frame, I can imagine that gluing to the inside edge might be problematic.
