No sound in right ear with Sony MDR-NC31E bundled headphones

[cdn86]

Hi, I bought the phone with bundled noise cancelling headphones and they worked flawlessly. Since then I've applied 2 updates from Sony and when I went to use my noise cancelling headphones after not really using them (I usually prefer my Sennheisers) I have no sound in the right earbud.

If I plug it into any regular 3pin 3.5mm jack it's fine, I have sound in both channels, and plugging other headphones into the Z2 gives me proper stereo too.

Seems to be a problem when the Z2 noise cancellation software and the noise cancelling headset try to play together.

Any thoughts? It's only happened recently.

Well said I also bought due to the noise cancelling and it does not even work anymore since lollipop update, also tried software repair... Still no sound in right ear. It's clearly a software problem and Sony should send an update

My brand new z3c phone does not work with MDR-NC31E earphones either properly, in my case only the right earbud makes sound (on the right one noise cancelling works,  but the left bud does not make any sound at all) All softwares are up to date, android ver. 5.1.1 Xperia software 23.4.A.1.200, still does not work properly. Sony Xperia Support team, users need a workable solution here!!!!! 

Anybody else found a fix for the issue?

If you are facing issues with your phone, always try to boot to Safe Mode by long press on Power Off button and see if the issue persisted in Safe Mode. If not, than you have a rogue app that is causing the issue. Hunt for it and uninstall, you should get back a perfect phone.
