Finally a great running headphones

After 2 outputs, one running in the rain, I am satisfied at all points of this helmet. Kudos to the designers of this product! The investment is worth it. The 25 euros without helmets available on Amazon son have almost nothing in common with it.
Very comfortable (malgrés no adjustments - Attention therefore can - being "the small ears"). Very good sound, very satisfactory Connectivity and ergonomics. If something to say, it would be the cover that can serve cuff, I think it a bit too thick / heavy compared to the cuff Decathlon ... but it is perfect as a storage case.
