High quality finish, very good sound radio / mp3 / phone call, the microphone is highly effective (not necessarily need to have it close to the face). I previously had another bluetooth headset brand with Pickup on the wire and so he must get used to manage calls directly on the body of the unit. So you must select the appropriate position with the clamp which is effective sometimes to the detriment of discretion and the feeling of being a little "arnaché" but it's still acceptable. For radio, I find the reception sensitivity limit indoor frankly (it sizzles and often loud) and the inability to store their favorite stations is somewhat painful to use ... (for against outside, c ' is good). But the final impression is still very good, sound, light weight, Bluetooth compatibility on android, miniaturization and the general concept are excellent!
