ve duke is awesomeI know you said you preferred universals, but I would at least take a look at the Custom Art Music One. It's a fairly inexpensive silicone CIEM that sounds amazing for the money. The isolation you get with it as well is mind blowing, even if you've never gotten any sort of CIEM before, I'd heavily consider it as it sounds like it would fill what you are looking for fairly well.
Thanks I already own a Custom Art product which I use for home listening and its great. For some reason, I get better isolation from universals with deep fit and foam tips than customs. I must have funny ear canals. That's why I'm looking for a universal.
