What junk. The first pair I received, only 1 earbud worked. I returned it for an exchange. The second pair I received worked for about a month and now the same problem happened. Only this time I can't return them because return time ran out about a weak ago. So in conclusion, if you like earbuds that one side goes in and out with static noise, then this is for you, otherwise stay away unless you like throwing $$$ away.Update:I'm giving 50% apologies to the vendor. Although the first pair did not work 100% (even when moving the chord), the second pair (replacement)may work. I bought more headphones (earbuds) and same problem. It has to be my sansa clip 4+ mp3 player. I'm going through the process with them for a replacement.
