I was just looking at UE's web site, and it appears they have added a two IEMs to their "Super.fi 5" line (in addition to the Pros and EBs): The Super.fi 5 and the Super.fi 5 VI. The latter being the "iPhone" version of the former.
The Super.fi 5s are a single armature design. Amazon is currently selling them for $150.00 as compared to $190.00 for the Super.fi 5 Pros.
I do like the more durable, metal design of the Super.fi 5s.
Has anyone compared the two?
