I'm interested in that particular IME, but I am a little bit confused: Some shops offer UE Triple.fi 10 (without the PRO), others are offering Ultimate Ears’ Triple.fi 10 Pro. So, are there two models? What's the difference? Also, there seem to be two different packages: 1. blue and white: http://cgi.ebay.de/Ultimate-Ears-Triple-Fi-10-Pro-TOP-Zustand-OVP-/140541921766?pt=Kopfhörer&hash=item20b8f389e6#ht_1438wt_1139 2. black: http://cgi.ebay.com/Ultimate-Ears-triple-fi-10-pro-Headphones-No-Reserve-/250812620326?pt=LH_DefaultDomain_0&hash=item3a6598de26#ht_725wt_1139 What's the difference? Can anyone help me? Thank you!
