@Will > Sorry to hear about the problems. I haven't even had a chance to try out the DJE units yet! Sadly, I think it's a problem with a faulty cable and as you're under a year, you're under warranty. Please contact technical support - links are located to the right. They can sort you out.
Sorry to put it in this section but i didn't know where else to put it, So i have had these ear phones for about 4 days now and I am already experiencing the ear phones shorting out and crackling under any volume on my iPhone. Sometimes the left earphone doesn't even make sound at all. I have had these problems since the very first time i listened to them but i gave them the benefit of the doubt and just thought it was the cable wearing in but it has only gotten progressively worse. To be honest i am very disappointed after waiting for months for the ear phones and i was hoping to get the pioneer quality I'm used to. I'm really not sure what to do.
