And yes, so far they've been pretty good at staying in the ear. The only thing I can say is that I'm still playing around with the different tips (there are 3 pairs of regular tips, 2 pairs of triple flanges, and a single pair of bi-flange tips. I've been working through them). Today the smaller triple flange pair felt like they were coming a little loose but not enough that they would fall out of my ears any time. Just not as tight as I would like sitting in front of my computer.
I've also used them for general listening the past few days. Nice sound.
