A little update on my fitment issue - my right ear has stretched out accordingly, I'm feeling no difference in tension between left and right now. Even when putting them in first thing this morning - in fact my left ear my feel a bit tighter now.
What did I do? Just wore them lot over the past couple days, maybe 10 hours each day - and shoved/twisted the unit in my right ear alot to help loosen things up, to the point where it was getting a bit numb/raw.
I'm a little stunned, the inside of an ear is more pliable than I expected.
Also on the upside on my 7th day of ownership, these things are really blossoming tonally. Not sure if it's related to physical burn-in, brain burn-in, or my ears relaxing (ie. creating more space in the canal), but I'm not getting that overly thick, veiled presentation anymore - and I'm hearing the treble considerably better.
