I really want to like my 900S but I have two complaints;

I don't get the isolation I get with my Shure E5
Bass is too polite

I'm thinking these are related as if I had better isolation I'd get more bass response.

I've been using Comfy tips medium. I ordered large to see if that helps. I've tried every tip that came with the 900S but no where near the isolation of Shures.

Suggestions?

Much better isolation with large tips.  Also upgraded to Fiio E12A Amp which sounds more lush.
