This noise reduction headset was good. I use it only for journeys by train (long runs). Major fault: noise reduction glasses + = greater than buzzing without noise reduction ... So reading or listening (if you need glasses), or read and listen to the ambient noise. The function to listen without removing the headphones is fine when there is no noise ... if not, it is mainly the sound that passes! Why was allowed to call (by phone) with the controls of the helmet? this is ridiculous: we do not know who called and someone we can call by false manipulation (it happened to me ...). Receiving calls would have been enough! hence the rating.
