Music comes through only from left earpiece of any headphones - HTC Desire 620G

So I bought the HTC Desire 620G one week ago and haven't used headphones on it since today.
I plugged them in and noticed only the left earpiece is working. At first i thought my headphones were broken and plugged them in another phone and my PC and they worked perfectly. Then i tried using other headphones, tried 3 other headphones still same problem.
Also tried to see if i can clean it with a toothpick but no luck. Any help appreciated :) :)
