Those are ultimate Ears brand IEMs
I would guess if they are only 80 bucks they are part of the metrofi line.
The cool thing about UEs the cords are replaceable, they literally pull right out of the bottom (I have replaced mine once) and are usually around 20 bucks. So my guess is UE is making a speciality cord that plugs into any of there cans.
I have ordered the Belkin and I gotta say I am not impressed. It is kinda bulky where the adapter plugs into your headphones and the part that plugs into your phone does not have tension relief on the cord so I question its durablity.
I shot a message over to someone I know at UE, hopefully tomorrow we will hear back. Im stoked, I would love to get a set of cables like this for my superfi's. I was wondering when they would cash in on that. :P
One more perk over shures

Do you have the link for the head-fi thread?
