Post [Q] Noise in the left side of the headset

Hello guys, I bought the the G3 this weekend but have experienced very annoying noise in the headset while listening a music especially on the left side. Did anyone also have this issue? I'm using Koss Porta and I'm on stock rom. Thank you

after some googling I found out the same issue were also with G2 after Kitkat update. G2 tweaksbox helped me to temp fix the issue.
