More than correct sound quality and good battery life

I had the opportunity to receive two pairs of headphones test of this trademark.
Clearly, these headphones are designed for runners. Their light weight and autonomy really do a very good choice.
So, we would expect that the audio quality is slightly rotten but it is not.
We are far from talking about hifi course: mediums are correct, somewhat gaudy treble and bass relatively low.
Nevertheless, overall, the sound is balanced and we can really listen any kind of music without being frustrated by poor sound.

In terms of autonomy, my tests have consistently given more than 6 hours but rarely 7.

Regarding ergonomics: the weight of the atria is really light and narrow enough headphones section even for young teens. Nevertheless, it will take time to find how to place them so they stay in place. Ergonomics is not a problem but this is not the strong point of this model (unlike the M2 model: ;camp=1642&creative=19458&creativeASIN=B00MMXLJOY&linkCode=as2&tag=leblodeman-21&linkId=BPQD56USIAIQSC3A which is much more pleasant and easy to place in the ear).

Pairing is relatively easy, and unlike many other models I've tested, you do not need to refer to an LED or beeps a few meager whether the association worked. Indeed, you will see that will tell you one (in English) that the association is successful, the headset is turned on, etc ... Practice. By cons, without knowing how I did, I managed to pass the Chinese ... Immediately less convenient even if it has not actually been blocking.

Finally, given the price (under 22 at the time of this writing), these headphones are a great buy. However, I tend to advise the model I mentioned above. It is even cheaper, the sound quality is identical and the ergonomics are better.
