First of all, I have to make a disclaimer. I'm an engineer for Westone Laboratories and one of our product lines are in-ear monitor headphones.

So, with that bit of bias clearly stated up front - let me ask you if you have considered the following questions:

1. Do you track any kind of acoustic instruments into microphones?

2. Do you listen to music on an iPod type of device?

3. Do you travel on airplanes or public transportation very much?

Here's the reasoning behind those questions. If the answer to #1 is yes, then I would immediately rule out open-back phones of any kind because of bleed issues while tracking.

If the answer to #2 is yes, then I would say that in-ear monitors are an ideal solution for you, because they are triple-use. You can use them for tracking in your home studio without any issue of bleed and quite flat response to 'hear what the microphone hears', and go right from there to the best sounding iPod/personal listening device headphones you can imagine and be discreet about it, and pack them into a pocket for a nice quiet experience on the airplane. I like many of the headphone models shown above (personal experience with the AKG 240 models and Sennheiser models), but if you wear those out of the house, you look rather silly.

All of our universal fit models offer 25+ dB of isolation from outside noise.

I would shoot for the UM3X model. http://www.westone.com/catalog/um3x-true-3-way-monitor
