Both interest me.  Not sure which I would like. Anyone have direct comparisons to each other?  Wonder if anyone else is wondering the same thing.
 
I loved the T1 & HD650, didnt really love the k701 or the HD600. if anyone has some quick thoughts between those.

Since I own both, I'd say go with the T50p if you want treble, details and speed and the ESW9 if you want great vocals and a "fun" coloration, though they might get congested on fast and complex music. On another note, I find the T50p very comfortable with glasses, since they have a smaller size than the ESW9, so you might take that into consideration. These are only my first impressions of the T50p, before burn-in and during the "new toy" phase, so take them with a grain of salt.
 
I would also ask on Headfonia, their first impressions were posted by someone who owns both.
