Um, just exactly who do we think we are? Petition Etymotic? If head-fi were to blow up right this minute I seriously doubt Etymotic would even notice. We constitute such a small percentage of the market that our purchasing power is completely irrelevant. Our opinions and feedback aren't irrelevant though, since we're a very vocal minority, but I have yet to decide if that is a good thing.
We can influence boutique manufacturers that rely on us to market their limited-edition products, and we can certainly advertise mass-market headphones by providing lots of positive hype around them (which explains our sponsorship), but a major company like Etymotic, that sells a lot of products to the professional market and has the name recognition to stock its products in more upscale audio stores, doesn't need us, nor care.
I also remember reading that they don't like to deal with crossovers and multiple drivers, though it was so long ago that my brain, such as it is, could be playing tricks on me.
P.S. Didn't mean to sound bitter, just making my point. Hope no one takes offense.
