no fake tf10s. there was a $95 tf10 a few weeks ago so the price you see is pretty normal. most likely from people who got the tf10s for 95 and are trying to make a little profit

the technology in the trip fi's are very hard to reproduce with counterfeit methods. also 143 isn't that cheap

I find the tf10 to be as comfortable as most other iem's however they are rather large and most of the body sits outside your ears so you need a deep fitting tip like a triple flange or a monster foam tip to hold them in place in my experience ,but each person will have different fit experiences .
 
Ultimate ears did used to make double flange tips ,don't think they do any more .Many other large bore tips from other brands such as monster and senheiser fit the tf10.

Awesome, just bought them.  Thank you everyone for all your help!
