question:
I am on my 3rd power cord. The first one burned out after only a couple of months. Amazon sent me another one. Only lasted 3 months and now has stopped working. This cord also gets really hot. Not sure how this got such high ratings. Wish I'd never bought it. At least it was cheap! :(
answer:
Bad review

question:
The sound is good enough and the Bluetooth connected great but after a few months they stopped working. I contacted LG for a replacement which was quick to get here with no hassle. So far so good, however, their claim that their product contains "durable materials" has me doubting my purchase. I've worn them every weekend day while work at an office since December 2013 (maybe 2 hours a day, if that) and today is finally the day when one side died.
answer:
Bad review
