I was specifically talking about the TWS adapters that exist for MMCX connectors. Imagine using a cable with a memory wire (the type for CIEMs) but instead of it just being a thin rubber sheath with a paper clip, it’s a huge piece of plastic with a battery in it. Without a memory wire an Etymotic is very comfortable over the ear (I’ve done that). But if you get an CIEM cable and try it it’s not a pretty feeling.
True, although I I've also seen people doing it (https://www.head-fi.org/threads/if-...-thread-for-you.538615/page-973#post-15405931). Personally, I don't think it's comfortable either way, and would either use a short-ish Bluetooth necklace adapter cable unit or any Bluetooth receiver that's small enough and has got a good included shirt clip.
