Skullcandy Agent Headphones
I bought these for my son's 15th birthday in October. By the second week in November one side didn't work anymore. I bought another pair, and low and behold, on December 2, one side failed again. It is a wire issue, because he can fuss with it and get it to connect for a brief time before it breaks again.
I will be getting him another pair of headphones for Christmas, but I will be looking beyond Skullcandy.
