I had previously been several wireless headphones and have to say this one is the sound of her by far the best. In some songs sounds come to light that were not previously noticed. The connection via Blutooth funtioniert quickly and easily. After the device was even coupled with my iPad, enough only to turn on the headset, and the sound can be heard through the headphones. Also the wearing comfort is very good. The headset is relatively light and sits very smooth on the ears. When placing the music is automatically stopped and continued when recovering. The receiving calls I have not yet tested. Although the filtering ambient noise works, but there are not all the frequencies filtered out, with very soft music, a hollow rest of the exterior noise remains. The headset includes but from so much that you actually do not need. Even the battery lasts many hours long, with such headphones not also goes without saying.
