This is the best of the 4 earphones I bought it last month. The attachment to the ear is excellent, I can almost do without the small plastic hoop provided to secure. Setup is child Linux Fedora, a little more difficult on Windows 7 but when you do it yourself!. The sound quality is good in communication as in multimedia. The on / off button on the side adds an excellent ergonomics, it must be emphasized. Salt negative, the command to lower the sound from the headset is not obvious to understand at first but it will not detract from the overall appreciation of the product.
