I have small ear canals. Those tips are actually from the stock canalphones I got with the Sony player as recommended by some on this forum. If you've tried the EX082/EX90, I find the fit with the Denon is more comfortable and they isolate a tiny bit more at the expense of a lot more microphonics (and I find over the ear without memory wire doesn't solve the microphonics much). Despite their size, they seem to stay put fairly well.
