Interesting question. I am not an audiophile, but definitely "hear" when the sound is "not good enough."
Your question makes me think. Here's my subjective answer: I have not noticed a significant difference in the sound quality (remember--not an expert). It is still excellent. But I am quite sure there is noticeably less intrusion of ambient noise. It does not filter as well as tight-fitting in-ears, but I don't like those--for my use, hearing my name called is better...wife doesn't slap me when I don't answer.
These, as you know, are not big, soft, puffy rings. They are small, soft, slightly puffy rings--as they must be being on-ear diameter rather than over-ear diameter.
Comfort is MUCH improved over the stock foam though. That was my objective, and it is achieved. I would encourage anyone owning Koss Portapros to order some.
