Ok, thanks for reply. I did know the headset had a 5 pin socket, before i bought it. But on your products side about the headset (https://www.sonymobile.com/no/products/accessories/high-resolution-audio-headset-mdr-nc750/) there is no information of which phones/devices it fits and not fits. I only get three advertisements in the bottom, telling me that this works great with: Xperia Z5, Xperia Z5 Compact, Xperia Z5 PREMIUM. Moving on to the full specs of the Xperia M5 https://www.sonymobile.com/no/products/phones/xperia-m5/specifications/) I do see that it dosent support DNC, and Hi Res, and that's okei, I can live with that. But there is no informationtelling me that this device does not support 5 pin headsets. So I decided to buy the headset, because i found no information telling me it won't work. I also thought that since I have a Sony-phone (released 2016 I guess), there wouldn't be any problem with a Sony-headset. Where can customers find information telling them this headset wont fit your phone?

I put the earphones as far as into the phone as possible. The noise I get from the earphones is a constant knocking sound. My Smartconnect app starts playing music as soon as I put the earphones in the phone. The quality of the music is horrible though. The earphones fits the Dualshock4 and my computer.
