The Coby CV-185 can be founded pretty much everywhere for under $10. After reading joker's review of these headphones, I thought why not since they are so cheap.
 
I bought these headphones at Marshall's for $7. The headphones come in a plastic box like any other cheap headphones come in.
 
The built quality of the headphones are more than adequate for a headphones its price. The only qualm I have with the headphones is its foam padding lining for the headband which almost feel like paper.
 
As far as the sound quaity goes, it really depends on the source. On most source, these soundphones sound ok especially for the price. These headphones are very balanced.  However, when paired up with my Zune HD, the sound retains its balanced sound, but is much richer with much more depth.
 
Overall, these headphones are good value, but if you have a Zune HD or any other Zune, these headphones will have great synergy that makes them shine.
 
 

I bought these for about $25 shipped. Out of the box, the sound was good especially its mid; however, the bass was lacking, and the soundstage was narrow.

However, once paired with the Fiio E5 especially when set to the secret middle position, the soundstage was wider and the overall sound was much more balanced while retaining its strong mid. The bass was much stronger and tighter. The mid and high also improved as well. Overall, the sound is much more balanced and pleasantly warm. It is worth noting that the UHP606 specs stated that the impedance is at 29ohm which is higher than average IEMs so a portable amp such as the Fiio E5 is needed with this IEM.

As for construction, the UHP606 is pretty durable although it's entire body is constructed out of plastic. The wire is clear plastic, and there is a L-plug instead of a straight one which I prefer.

Overall, these IEM is a very good value that sounds very good if paired with an amp.
