I guess I'm seeing more as a coloration from the phone itself. That perceived transparency or rawness is on every track and not track dependent when using my tracks and gear. With the other two phones I can more easily tell which tracks or albums have been mastered better or more cleanly. With the SS they all sound the same so far. Until that changes I have to presume it's the phone and not the track I'm hearing. I just don't hear it as finding new information that was lost on the ES5, UERM or HD800. As for air, well, that's something different altogether. They are vented afterall.
For those that haven't heard these phones we are talking about rather minute discrepancies here so I don't want to give the impression any of these phones aren't up to snuff. The SS is cool as heck. It takes the ER4 and kicks it in the nutz.
