I ordered a pair as well. I haven't received them yet, but let me just remind the recent posters in this thread to give them a fair try. I'm not saying burn-in, but generally it can take someone multiple hours to adapt to the sound of a new IEM/headphone for the first time. I have seen reviews of these in which they are said to compete with the Triple.Fi's, albeit with a different sound signature, so I find it hard to believe that they're mediocre to the point which is being indicated above. (I own both, so when I get my pair I will be able to elaborate upon the comparison to the Triple.Fi's).
I too am worried about the build quality, the reviews do make me worry here. Hopefully if well treated, they'll hold up.
