Why doesn't my earbud not work in one side???

[AC Question]

I have an XGody phone and I love to listen too music so after I got my phone I was keen to sit down and listen to my spotify. But the problem is is that every time I plug my earphones in they only work in one side. To start with I thought that it was just the earphones being broken. But now it seems that every pair i get they only work in one side. How do I fix this????

Might need to take it to repair place, perhaps a wire come off inside or some other open circuit occured...
