Bad: sound quality worse than Apple EarPods

The problem for me at the level of sound quality that I find mediocre, well below the original Apple EarPods.

Sound quality:
6/10 for Apple EarPods
3/10 for MPOW Cheetah

The sound is muffled, flat, and when you lower the volume to a minimum, we always hear a kind of breath in the headphones ... too unpleasant.

Easy connectivity with iPhone, shortcuts are available (volume + and - / previous and next track).

I use it at the gym to run on carpet, and no problem at this level, the headphones tight fit and are comfortable enough.

So the headphones do the work, excellent quality / price ratio (nothing bluetooth at this price ...), but it should not be difficult level sound quality!
