In the seemingly never-ending chase to find the ideal tips for my shure 846, I decided to use the core of the Shure olives as the sleeve to accommodate the larger bore Symbios. Early impressions are really favorable. I can post pictures later if anyone is interested.
I'm glad you like Symbio on SE846. Actually we have Symbio Wa for these type of IEMs : https://symbioeartips.com/termek/symbio-wa/
Initially I just tried to shove them in my ear with Andromeda and I came to the conclusion that it felt uncomfortable. Then I remembered with comply i always correctly compressed them before inserting. I don't know why I assumed that wasn't necessary with these (silicone tips I guess) but while it doesn't show, it does compress. I've since compressed them properly and these give me the most consistent / secure fit with the Andromeda.
Yes, there is a note in item description: "Read the manual please", but seems it will be useful to attach a manual in package. Thanks.
