The best headphones for sports

Hello,
I searched long headphones for sports, I've tried a lot but I have never found THE ideal helmet ... Either he kept well but the sound was bad or vice versa or both. I'm pretty hard in terms of sound and this time I found the almost perfect helmet. It holds very well, we did not feel at all and the sound is really above all the ones I've tried (and there were a bunch ..), isolation is not very " strong "so we can use it in the street without worry. Finally, the fact of not having cable is clearly a big positive. In short, very happy with this product. Note that I use for running over distances of about 25 to 50 km a week.
