On paper I read that the size headphones partiuliérement made them hard to put on and especially not to hold in position .... I am mocked and I was wrong. For standard ears, it is impossible to keep them in position more than 10 seconds because their tip is too big. In short the idea is good, its not bad, but the item is unusable even changing the plastic pads. You do not want to lose a euro 20aine, forget this article.
