Input:
After breaking them in, I enjoyed the full sound of these ear buds for about 5 months before the left bud stopped working.  It's been 11 months now and the other bud is starting to go out.  Something else I found interesting was how they label the left and right buds.  There is a tiny "L" on the rubber connector on the left bud, but I didn't notice that until like a month ago.

EDIT: After contacting customer service, the issue was very quickly resolved and a new pair has been sent out.  Thanks, JLab!
