My Mdr-nc31e noise cancelling head phones suddenly stopped working. I recently bought a XZ about a month ago or so and started using the headphones on that device. Before that I used them on my Z2. I've never had any problems with it , but it suddenly stopped working. Granted, I've used them for about 2 years so they might have received some bumps over the years, however I've keep them in good condition and feel like there shouldn't be any reason for it to suddenly stop working. Also, I plugged them in my computer and it works fine. When I plug it to my phone, my phone doesn't even detect it. Other headphones work on my phone so I'm not sure what the problem is.
