Sony MDR-NC31EM No longer working as headphones, just mic

[AvkommaN]

Tried with support but they couldn't replicate the issue, whenever I plug my MDR-NC31EM headphones in my phone it thinks it's a mic so no sound is played through them, at first I thought it was just the headphones themselves so I ordered a new pair but the new ones act just the same way, I don't believe it's a hardware problem since all other headphones I've tried work like they should, the problem also did occur at the same time as I updated to 4.4.4 so I'm wondering if it's a bug or something, does anybody else have the same issue?

I did a software repair as adviced by the support at Sony but that didn't work, I don't know what to do, now I'm here with 100 bucks worth of headphones I can't use!

Hi, do you have the noise reduction ones selected in the Settings menu......

Hey, yes I have tried all of that, and yes noise reduction is slected from the list of available headphones

If not then access settings, go to "apps", go to "all", find "SmartConnect", then clear data. And restart the phone again.

I just have a picture of the microphon at the top left handside of my phone when headphones connected :///

Have tried clearing the data from smart connected as well was reading in another post...

Check the 3.5mm input for any dirt.

Try booting on safe mode. And check if the problem persist.

Same problem in safe mode, I could try cleaning out the jack, putting the phone in water would draw any dirt out?

Use a cotton swab to clean the 3.5mm input.
