Yes, I have. Although, only with original Xiaomi Mi2 earphones. I think for this there are two explanations:
1.Type of earphones. Please see this for explanation - http://www.techhive.com/article/200...ifferent-types-of-headphones-illustrated.html
When I switched from earbuds to canalbuds, sound volume and quality increased.
2.Bad quality of earbuds. Maybe this is the reason and you can try other earbuds. I only had canalbuds, that's why I used them.
