Bought at the base to record video in motorcycle (camera + microphone on the headset in the helmet). It records far below 30-40 km / h. By cons, beyond 40 km / h, the microphone can not stand the sound of wind, engine noise and the sound of voices. There are too much to handle for him and he made micro cuts. It's still "audible" but it's frankly not as wacky quality.
