Apple Earpods no sound in right ear NO DAMAGE AT ALL

Hi, my apple earpods were fine yesterday, absolutely fine but today I woke up to see that there was no sound in right ear. There is absolutely no damage and I just bought them like a month ago. What should I do? I live in Pakistan so can't get them checked from Apple. What should I do? Once I was experimenting with them and when I licked the connector and put it in a certain angle in the headphone jack, it worked for a while, then again the sound vanished. Moving the wire or any part doesn't give the sound back because there is no wire damage. Can someone give me idea of what could it be?

One thing that knocks me if that the headphone jack on my pc is quite tight so I always twisted the connector like a screw and then took it out, did this disrupt the connection in the headphone connector? Please guide me,

thanks,
