Bought mine here 1.5 years ago.
At first the bass was all over the place, really terrible sounding, but after burn-in they sounded really nice - warm but leaving clarity and room for the rest. I didn't used to believe in burn-in, I guess I do now.
About a week ago the cable started shorting out between L+R unless held in a particular angle. I expected a $70 pair of earphones to last longer. I treat my stuff well, before these had a pair of Klipsch S4 that lasted ~4 years.
Contacted support, but since they are out of warranty, I'm not optimistic.
tl;dr -
thumbs up for sound (after burn in)
thumbs down for build quality
