Thanks for the review, i am getting rid of my 215s and should be getting these any day now. 

I went through the same thing between the shure and r50. I got the 215 for xmas and am now returning to them. They don't have the sound I like. Lots of bass, and lots of unclean too much for my liking and the width isnt what i wanted to hear. I ordered the r50 and am now waiting. In the meantime...
