Dynamic (C)IEM with Very Good Isolation?

Hello, this is my first post. I'm looking for an IEM or CIEM and was hoping to get some recommendations. This is what I'm looking for:

1) Very good isolation. I previously owned some acrylic shell CIEMs and to be honest I found the isolation disappointing compared to my old Etymotic universals (no fit issues by the way). So I guess I need either a silicone CIEM or IEMs with isolation comparable to my old Etymotics.

2) Sound Signature. I think the sound signature I would like is U shaped with more of a boost in the upper mid and treble area than bass, but not neutral bass. I would still like clarity in the midrange and not recessed.

Any suggestions would be most welcome. Thanks in advance.

 

post this in the IEM general discussion or the All purpose advice thread please
