Also, this struck me. If the Comply T400s work with the IE8s, and they do (in terms of fitting on the nozzle), what is the difference from using the Comply or the decored olives? The olive foam is better for SQ? I have olives and they can sound fine, but not better than Complys to me. The lack of a true sound tube allows a higher SQ? That has to be the only difference. Too late for me to try the IE8s with the de-cored olives, but I can try them with other wide circumference phones, like the RE2 or VSR0PRO II. I just had to ruin a good pair of olives to try it, since I am saving them to try with the UM3X, if I ever get those phones.
No matter, but good find if it works for IE8s owners who are having fit/isolation problems.
