A few days ago I posted a thread here, and got some really good responses...but crunch time has approached my good friends.  I recently spent (a lot more than I planned) on a new PMP, the Cowon C2.  I understand that Cowon has almost unmatched audio quality, and I really want a good pair of IEMs to go along with them.  My MAXIMUM budget is $100, but I would prefer to keep it around 80.  No microphones are needed, and I don't necessarily need anything fancy.  So far I have had these recommended to me...
 
Etymotic HF5
Shure CE215
Audio Technica ATH ANC23
Ultimate Ears 600
Bose IE2
Velodyne V-Pulse
 
...and a lot more.
 
Which of these is the best bang for your buck in terms of durability and sound quality, and if these aren't satisfactory, any more recommendations?

Depending what kind of sound signature you would like Shure SE215 or UE 600.

How are you finding your Cowon C2?

The price that I can get the UE 600 for right now is very appeling as well, so I might just go with those. I love my C2 BTW, best little player I've ever had!
