I don't know what's wrong. I had two pairs of skull candies that died. I brought some v-moda's a couple of weeks ago and now there dead. The only thing I can think of is my brothers computer. He has a MacBook. I don't know if it uses a high jack voltage or what. On all of them, the right bud completely died. I was listening to music with my Moda's, then I let him use them for about 20 mins. Later I plug them in later and dead. I have they worst luck with everything.
