I'm actually using these right now. Mine are black though, they came with the Grado iGi that I replaced with my UEs.
I prefer them to the comply tips; insertion is much easier and I don't need to wait for the expansion of the comply. They don't FEEL as if they're any deeper, but I'm getting a similar seal and the same great bass that I liked with the Comply, sans the weird crackling I didn't like so much.
This tip looks very interesting, it has large bore (when compared to sony one's) and quite long for deep insertion. Does anyone know which tips are these, I pulled this pic from an old post in this thread
