No, you can't.
And since I paid $118 with the newegg open box special, you can understand why I like them even more.
Just to explain my POV more, I had the IE7s after the IE8, and just could not get a good fit and found them fairly unexciting. I sold the IE8 because I detested the fit, I like a solid seal, with great iso, and the IE8s are not those phones. Plus, at the time I had the Westone 3s and found them to be more dynamic (in the sense of excitement) than the IE8s, which were too laid back for me.
As for the Custom 3s, I guess I just could not warm up to them, but since I got them so cheaply at the time ($150), I wanted to try them out. I always felt they were missing something, not sure what now it's been so long ago. And I sold them to a HFer in the UK, who eventually sold them to mark2410. LOL.
Anyway, I realize they have a certain FOTM "glow" around them, but they have been out since November. I think it's more related to price drops than FOTM. Same with the CK10s. At $349, not interested. At $199, very interested. It's a good thing, since many of these phones come out with unrealistic MSRPs in my view. When them come more down to earth, of course people will buy and try them.
No one is staring at my MTPGs, not that I notice. Of course, they are too cold to even look up with this crappy winter.
