What are the differences between the "pro" and "proless" versions?
 
Here in head-fi, every good review i read is about the pro version, and in amazon the price difference between the two is huge ($168 to $409), so i was guessing the pro one must be very superior, but i'm not really sure why as i can't find it anywhere.
 
Here are their listings on amazon:
 
non-pro version: http://www.amazon.com/Ultimate-Ears-TripleFi-Isolating-Earphones/dp/B0019RBJOE/ref=sr_1_1?s=electronics&ie=UTF8&qid=1353436444&sr=1-1&keywords=ultimate+ears+triple.fi+10
 
pro version: http://www.amazon.com/Ultimate-Ears-IF-P7PSA0001-02-Triple-fi-Earphones/dp/B000JFJDAE/ref=sr_1_3?ie=UTF8&qid=1353435846&sr=8-3&keywords=ultimate+ears+triple.fi+10

Pretty sure they're the same thing.  But I could be wrong so I'm curious now.

Same IEM's.    Only the 10i is different with the microphone thing.

They are both the same thing.

The UE TF1Pro, UE TF10Vi are same IEMs but Vi version has iPhone compatible remote/mic cable. The UE10Pro are custom IEMs too with sharing almost same name as TF do.
