These headphones are of truly exceptional quality: the sound is very good, the atria insulate very well and are comfortable, the son becoming entangled (almost) not because they are flat, the design is simple and refined. I, who do not know this brand, I am very pleasantly surprised. Then of course, like any product, it has some flaws: the remote evil walking with my phone (former Android), it's expensive, and the wire length is not exceptional. But I remains very positive on this so 5 stars.
