Ok... I'm glad to hear that I agree with some of the cognoscenti. I own (ciem) UE7's and (uiem) Etymotic ER4's. Once I found out about the Comply foam tips for the uiem's, the ER4's blew the UE's out of the water in comfort, isolation, and fidelity. I'm a drummer and have very serious isolation...

Well, in response to the overwhelming interest to my initial question   I thought I'd follow up with my solution. I bought the Etymotic ER-4PT's. Extremely happy. The accuracy of the ER's beats out bloated bass of the Atrios hands down. I bought the Comply inserts and now have a monitoring...

I currently own UE7's and find that the hard plastic molds don't give me enough isolation (believe it or not!), or bass. I've been alternating with a pair of Future Sonics Atrios with their new black "comfort fit" foam tips and am super happy with the iso, sound, and comfort of them...
