One small problem, perhaps, but it surely comes from new like me who use this kind of headphones: this kind of effect "stethoscope" can be annoying sometimes. I mean the fact that we are so well insulated that we hear the slightest impact on the wire earphones and you can almost agree breathe in the calm atmosphere, which tends to interfere a little early. The position of the headphone in the ear is also extremely important to have an equivalent in both ears. So you need a slight adjustment period to find its own settings but then you do not regret the purchase ...
