Zero discernible noise. The mic is a slight thicker then the mic on the other model but as for performance and where, both this model and the other model sold by COMEXION are extremely similar and very easy to use plus the quality is excellent. I really like that the ear buds hold thier charge. The belt material is too thin and flimsy. So anyone looking for quality kitchen shoes, and if you work 55+ hours/week. It was all treble and no bass, no deepness of sound. Blister. The Unknown, because Im returning this after only 1. These shoes arrived very quickly. If anything breaks it will be the arms that hold the paper towels.
