I would actually disagree with this statement. My ears are really small and I have never run into this problem with comfort using any other over-ear headphones before. The average human ear protrudes 1.8 cm out of the skull, and I measured my M100 pads to only extend ~1.5cm deep uncompressed, so I don't believe this is an issue limited to a small minority. I actually personally think that for people who wear their M100 continuously for extended periods of time (around 2-4+ hours), the majority of them will actually experience the irritation/discomfort/pain of the driver pressing against their ear.
Whether this is a big misstep or not can be debated, but there is definitely room for improvement. Therefore, I am really glad to hear that V-Moda is taking action to remedy this
