Just bought a Mojo for my full size phones and would now like to get a nice set of IEMs.  For reference my full size phones are HD650 & K7xx and my music of choice is Adult Contemporary & Classic Rock.  I'd like to spend around $200 but am willing to spend more if necessary.  Lots of people recommend the Angie but that is way out of my price range.

I don't know what to tell you for that price range.
 
My only advice is to get IEMs with a higher impedance/lower sensitivity. I believe the Mojo is capable of up to 5Vrms at full scale, and since it attenuates digitally there is a loss of dynamic range involved as you decrease volume. ADEL U12 is an example of a higher impedance IEM. As you look though, be careful about the impedance curve and make sure you plot a final transfer function with the Mojo and the impedance curve of your prospective IEMs. The frequency response of the IEMs alone doesn't tell the whole story.
