We can conclude that these listener's a very good qualtié / price.
After one month of use, I have not encountered any particular problem, more I use them in the practice of sport (Running mostly). The effect maintains the intra and does not hurt to my ear, they hold without difficulties.
NOTE: minor annoyance anyway, the large size that makes a lot when you want to feel lengthen. At the same time my old (apple) non intra dérangeai me too ...
So I recommend it!
