HTC Desire 626G Headphones not working

[AC Question]

Hello i got the HTC Desire 626G today with headphones, but when i plug them in the sound keeps coming from the speaker and not the headphones, no matter if i use the ones that came with it or other ones

You're sure they're fully pushed in? There is sometimes a high resistance to the last millimetre or so.
