The best I have is them

I have all kinds of headphones, but it's in perfect shape, it does not move, does not fall, if the sinks are very low very good, comfortable to wear and very discreet (though son are blue) because it fits perfectly in the ear and does not exceed.
Only drawback, it twists easily, the shape of the ear hook is doing its job so hook grabs all the time in the wire that is more of a silicone texture that clings so we can say.
It must store it carefully there is good, but hard to put in the backpack .... .... what happened to the left for a true half-minute détortillage!
A small sliding ring as the Iphone helmet would have solved the problem.
But the helmet is fitted with a clamp which bit do the same for storage of the helmet.
I am delighted and heavy user, it cleans more easily.
