The sound signature just so happens to be very similar to a pair of IEMs I adored, the original CCA CRAs, so I'm a happy camper in that regard.
The housings are nicely made, the cable is very flexible (a bit prone to tangling) and high quality, the jack as well.
However the metallic open backs (which made the IEMs sound more airy and wide btw) are prone to coming off of the IEM with no prior warning.
I fixed them with a drop of superglue but still.
If they fix this issue at the factory they have a winner on their hands. If not, for $28 it's hardly acceptable, no matter how pleasing the sound is (and it is).
