Good point.
I've had trouble with a good fit with all the previous earbuds I have used. I believe in the thread link offered above, some people mentioned that they had trouble with the new tips that were included. But I'm sure you went and read that thread as well.
My Sennheiser 600's bother me as well, so maybe I just have a hard time with it all. Let's hope they do provide a good fit, and I'll get them just in time for spring skiing.
