Lightbulb Cowon D2+ at 90 Ohms

Hi! I'm looking to buy some Ultimate Ears IEMs which have an impedance of only 13 Ohms. When I add impedance adapter of 75 Ohms that would make total of about 90 Ohms. My player is Cowon D2+ of course. Right now I have Head Direct RE2s and I listen to them at volume of around 15. Could my D2+ drive 90 Ohms easily? At which volume level would I have to listen to my headphones then? How would it affect my battery life?

Thank you very much!

what impedance adapter?
I've tested the TF 10, with Westone 3, Westone UM3X. All I tested in volume at 20, plus minus 1 with the different phones I remember.
Strange someone can listen to it at volume 15, considering I am a person who don't blast my music already and using IEMS, I am listening at 20

The D2 should be able to drive 90 Ohm easily. It will be quieter of course, but still loud enough. It shouldn't really affect the battery life much - especially not considering the D2's already overly beefy battery.

Yeah I know it will be quieter at the same volume. But what do you think, if I listen to 16 Ohms at volume 15, at which volume would I need to listen 90 Ohm phones to get the same "loudness" in my ears if you know what I mean...
