What are you guys using? I have a pair of Westone CR1 custom molded. I got them in 2008. I guess my right ear has changed (they say they do) because the right earbuds keeps coming out when I take off my helmet. I paid $175 for mine in '08. They are $300 now!
I'm using Westone ES60 and love 'em. From what I was told: if your ear shape changes you can send them back to Westone and they can place your drivers into new housings.
