Pros: Very very handsome
Cons: I suspect they're dressed up cheaper models
I listened to these very carefully, and although I almost fell in love with them and their very businesslike appearance, I did feel like an idiot for wearing something that's all about its looks. Swapping between these and similarly priced earphones I found that while they're inoffensive, they were doing nothing out of the ordinary besides looking like a million bucks, and their writeup on Senn's site and the packaging seemed to back this up.
As I'm writing this I kind of wish I still had them, but at least they sold for their cost on eBay.
