My ear canals are too narrow for my prestige and I need to downgrade
How do you mean? A refit?
I agree! As much as I love using CIEMs, there are times when they can be a little cumbersome - I hate taking them out to answer calls, for example. In this regard, a universal IEM is a whole lot easier, and more convenient to use.
Something that may help. To remove CIEMs quickly. Put your thumb under the bottom of the CIEM and lift. Should pop right out.
