I tried to insert my headphone into the audio jack and I found that the connection is not tight and made the sound coming into the headphone distorted. Anyone encountered the same problem? Anyway, I am using ATH MX40 with the original cable provided by Audio Technica.

I am having some issue when plugging in earphone , I use just normal headset. My issue is after plug in need to wait for 7sec then the icon only appear at the notification bar ,then only won't face any auto disconnection. If I straight plug in see got the icon up there ,later on it will auto disconnect after few second . Compare to.my Redmi Note 4G, it won't plug in all the way, after abit twisting it will pop out from the port. By the way, I didn't face any audio distortion.
