Yes I am. I have it set on "acoustic", as it sounds best with the music I play.
The Sennheiser CX 300-II IEMs that I use are rated at 16 ohms.
I've had some shitty buds before this, and I can understand the word painful coming to mind when turning up the volume. But the CX 300-IIs were an eye opener when I got them, especially with how they reproduced my music with the Zune HD. Crystal clear sound all the way to the top level and not ear piercing at all.
