We use the headset microphone for voice transmission, the sound is clear and wearing proper there are no disturbing breathing sounds. The thin design and the color is very light and unobtrusive to wear, yet mechanically robust enough. Small smear: During the last use we noticed faint clicking noises that are apparently caused by touching the wires together - the microphone capsule is probably relative to the holder not perfectly steamed. Since we are still a little experiment. At the price the micro but nevertheless highly recommended!
