I got mine off of amazon and after 6 month of daily use (and a little abuse) there were some issues. Both ear piece's shells came apart, the cable started turning green for some reason and the jack broke. All of the issues are fixable to some extent but the non right angle jack makes it hard to work with.
I have no comments on the sound quality because that is not my forte.
Here is a picture of the current state of my pair.
