Headphone jack not working

[Arzum]

Sound comes from the speaker when the headphone is connected. Headphone is not broken. I tried soundabout app. It doesn't work. It's xperia z5 dual

[Shabaal]

does the headphone has a removable microphone? If I try to use mine Cloud 2 without its mic exactly this would happen, if it has so, I suggest plugging, otherwise, I don't know '-' it can be the P2 type.
