Sure David...keep in mind that mine are not a good example as I have really big ear holes so the will appear larger. Also, these are on a FIBAE2 which is a small shell. Once I figured out how to insert and remove them I think they are really good. I have a great fit and they are really really snug so if I pull them quickly or at an angle they may stay in my ear. It is
not near as unnerving, when that happens, as it is with an eartip where you think it will go to far in the ear canal, these are custom they wont go inside further. The FIBAE 2 requires a slow steady pull straight out and I have zero issues. The IMR-R1 is the same, slow, steady pull. The Atlas will remove the same way. The shorter, smooth stem(no lip) nozzled IEM's do stay in my ear when removing the IEM, but that is to be expected and Piotr will also tell you they don't work for everything.
