Why any headphones are working properly on my Huawei P9 Lite?

AC Question

Hello guys. I hope you can help me with this big and strange issue I'm having.
Facts to know before you understand what's happening.

- I've tried 2 different headphones (The Original ones as well)
- The sound issue only happens with the headphones and not normally
- It is a Huawei P9 Lite with 5 months.

So the problem is:
When the headphones are pluged in, the sound on the RIGHT earphone plays perfect. The thing is that the sound in the LEFT earphone only plays if the volume is at more than 50% and the only thing you can hear is like "SHOTS" from the music. IT's hard to explain. It's like super loud (so much you must take out the earphone) peaks of the music. But you can't even understand what you're listening, The left earphone only "works" when at the song high peaks...
Its really hard to explain....

Any help :)?
